Outlook 2013 iCloud 4.0.2 Calendar Sync Issue

I am attempting to share several of my shared iCloud calendars to Outlook 2013. Before the latest updates to iCloud for Windows and Office 2013 I was able to do this but now it doesn't work. Outlook can still see the Calendars but new events created on either icloud or outlook aren't shared between the platforms.
I uninstalled iCloud for Windows from my computer and then checked to make sure the calendars had been removed from Outlook - which they had. I then rebooted and resintalled iCloud. After logging in with my AppleID I received a message confirming that I wanted my calendar and contacts put into Outlook. It went through the process of copying everything across but when I went back into Outlook, instead of my iCloud calendars being listed under 'Shared Calendars' they were listed under personal calendars. All the events were in there but it was not shared. This means that once again my calendar events aren't being shared between iCloud and Outlook.
Can anyone explain how to resolve this?
Thanks

I had a similar problem to @steve_proto's. After an update to iCloud for Windows, my iCloud calendars no longer appeared in Outlook 2013.
I tried following the iCloud troubleshooting instructions on Apple's support page https://support.apple.com/en-us/HT203521 but when I installed the latest iCloud for Windows, the check box for Mail/Contact/Calendar sync was missing, replaced by instructions that I should access mail and calendars via icloud.com. Outlook 2013 calendar sync with iCloud had worked before, but now my iCloud calendars were completely missing from Outlook 2013.
My setup: PC running Windows 7, iCloud for Windows 4.0.2, Office 2013 installed over Office 2010.
I think that the fact that I had installed Office 2013 on top of Office 2010 contributed to the problem. When I installed Office 2013, Office 2010 was not automatically uninstalled. Another issue was that Apple has apparently renamed "iCloud Control Panel for Windows" to be simply "iCloud for Windows." Most of the posts I found referenced the "Control Panel" app but all of the links sent you to an "iCloud for Windows" download page.
Here's what ultimately fixed the problem for me.
Sign out of iCloud for Windows
Uninstall iCloud for Windows
Uninstall Office 2010
Control Panel->Programs and Features->Microsoft Office Standard 2013->Change->Repair
Reboot Windows
Install latest iCloud for Windows
Sign in to iCloud for Windows
=> Now the check box is back, and iCloud for Windows prompts you for which calendars to sync with Outlook.

Outlook 2013 & Hotmail (Tranferring Emails between Accounts, Syncing Issues, Categories)

I would appreciate if someone could asssist me with the following Issues;
ISSUE 1 – Transferring emails between Hotmail accounts
I have multiple Hotmail accounts set up in Outlook 2013 on one of my PC’s. I also have the exact same set up using Outlook 2010 on other PC’s.
In Outlook 2010 i can easily transfer emails between Hotmail accounts just by clicking and dragging the email to the inbox of the other account.
I am unable to do this in Outlook 2013. When i try i get a dialogue box with the following message;
"Cannot move the items. The folders you are trying to change do not support this operation. Could not complete the operation because the service provider does not support it."
ISSUE 2 - Syncing Issues
I have this set up with multiple accounts on more than one PC. So when i access any of the PC's and click send receive, the Hotmail accounts are updated
to reflect the changes I made on any other PC (Ex. The emails that i left as Unread on the other PC will appear as unread on the PC i am at the present moment when I click sen/receive)
This doesn’t seem to be working as well on Outlook 2013 as it does on Outlook 2010. Example - When i click on send/receive i know that it should show only 2 unread emails but instead it shows
10 unread emails. This was never the case with Outlook 2010.
ISSUE 3 - Categories not syncing in Outlook 2013.
When i select a category on one PC using Outlook 2010, i noticed that when i go to another PC using Outlook 2013 and press send/receive it does show the category changes i have made.
I really enjoy using Outlook and Hotmail and have never even considered any other provider. I would really appreciate if someone could advise me on these issues, wether there’s something I can do to correct them or if there’s any intention of making any
changes so that the above will be fixed so that we can have the same functionality we enjoyed in Outlook 2010.
Thanks

Any way of being notified about this when it happens?
I'm going back to 2010 and would like to re-install 2013 when possible.
Thank you.
It's on their list, but major changes to the EAS protocol is driven by Exchange and as it stands now, I don't think they will implement it before the next version of Exchange comes out. After that, the Outlook.com team needs to implement the new version
on their servers and Outlook needs to be updated to support it.
The IMAP workaround mentioned in
http://www.msoutlook.info/question/765 is workable for migration scenarios.
As about getting notifications when it happens, following the
Outlook Team's blog might help but I'll announce it on my site as well (see my signature).

Outlook 2011 and mountain lion calendar sync issues... resolved (kinda)

Okay... I never really post to these boards, but I'm fairly ticked off that OS X keeps tampering with MS Office and it's syncing with iTunes and, ultimately, my iPhone. Apple support tried to push me onto the iCloud, but I'm not going to use that crappy feature. After many hours of trying to fix the calendar sync issue with MS Office 2011, I found a workaround:
1. Get the apple reminders set up to recognize the OS X Calendar program.
2. Confirm that your Outlook calendar data is recognized in the OS X Calendar program (it was always there for me)
3. Install MS Office 2008 (Entourage) --- You don't have to use it, but the older program still syncs with Mountain Lion.
4. Sync your iphone with itunes and ensure that your Calendars are erased (uncheck the Calendar sync box).
5. Click on the "Replace Information on this iPhone) for Calendars.
6. Re-sync the iPhone with iTunes.
7. The data should go up with no problem.
IF you are still having problems...
1. go to OS X "Calendar" and Add a new calendar called "Home".
2. move the Outlook data to the Home calendar (just drag and drop).
3. Repeat steps 4-7 above.
Since I've done these changes, everything directly syncs.
Hope this helps, and don't lose faith. MS will come up with some type of patch.

Outlook 2011 is not compatible with iCloud, it won't work and your 'workaround' may affect iCloud clients on the same account.
Don't use 2011.

Blackberry Outlook Calendar Sync Issue

We recently discovered a outlook calendar sync issue we can add items on the Blackberry and they will show up in Exchange. But you can’t change a calendar item from the Blackberry, e.g. if you create an item on the phone it will show up in Outlook, but if you use the phone to change the date or name of it Outlook will still show the old one.
We are running BES 4.1
We are running Exchange 2003

Itunes/Outlook Calendar Syncing Issue - UTF-8 Flavor

I have had the usual and much discussed issue of outlook calendar does not sync with iTunes. The recommendations have been to remove iTunes and re-install, even blow away all the configuration files as well, and it even worked for me once. But not this time.
I was running Windows XP, and all of a sudden the Outlook 2007 calendar just stopped syncing. I upgraded from XP to 8.1, and that was not fun, but inevitable, and still didn’t correct the problem. Now, if you never upgraded from XP to 8.1 – you can’t – at least it is not a direct flight. First, you have to upgrade from XP to 8.0, then from 8.0 to 8.1, and there is no upgrade in place from XP to 8.0. So what does an upgrade in place mean? Your applications and profiles are not carried over. Just your data (if you ask nicely) is carried over – but all applications have to be re-installed from scratch, and reactivated if there was license activation.
So, forget about re-install of iTunes, I changed OS, reinstalled iTunes and Office 2007 from scratch. And still had the syncing problem. So, I wasn’t getting off easy.
In searching, I found some debugging stuff which I tried, as follows to turn on logging:
So, I ran the following:
cd C:\Program Files\Common Files\Apple\Apple Application Support\
defaults write com.apple.Outlook.client.exe ShouldLog YES
defaults write -globalDomain SyncServicesLogEverything YES
defaults write -globalDomain SyncServicesLogPersonalInfo YES
And this turned on a lot of tracing. The tracing helped me understand what was going on under the covers, But I am not sure I was getting enough of the information that I needed to really zero in on the bad record.
Now, I will pause and provide some observation of my specific Sync.
An iTunes Sync on a Windows machine when using Microsoft Office and Internet Explorer is selected on the INFO tab of the page for the device.
Selections include Contacts, Calendars, Bookmarks and Notes.
One of the programs involved with Outlook Synchronization is: com.apple.Outlook.client.exe
The program is called when Outlook data needs to be accessed, and is used for contacts, calendar and notes when those items are paired between the iDevice and Outlook. Bookmarks are usually paired with the browser, for example IE.
During the sync operation, each of these are sync’d separately, that is why if you follow the sync actions, iTunes will reflecting what is being synced at the moment, for example “syncing contacts”.
When syncing the calendar, and iTunes is running a slow sync, it reads the Outlook calendar using the com.apple.Outlook.client.exe and does processing of the recursion and time zone information.
For example, for recurrence:
[5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Setting recurrence data <04300430 0d200200 000000ae 06000c00 00000000 00000400 00002120 0000e703 00000000 00000000 00000000 0000a0e7 980cc016 d10c0630 00000830 00000000 0000a005 00000000 00000000 00000000>
[5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] 0 recurrence exceptions
[5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Reading the Extended Exception Info (i.e. Unicode data)
[5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Done making compatible recurrence
For example, for timezone:
[5484 @ Tue Jul 01 10:30:43 2014] [YSLog com.apple.Outlook.client.exe] Could not create a time zone from outlook name, tried using name (GMT-05:00) Eastern Time (US & Canada)
Then the calendar entries are pushed, for example:
ca965dbc4717d9488fafc9266f1f829304082700 =     {
        "all
day" = 1;
        calendar
=         (
            ca965dbc4717d9488fafc9266f1f829382800000
"com.apple.outlook.freebusy" = Free;
"com.apple.syncservices.RecordEntityName" = "com.apple.calendars.Event";
        "end date" = "2020-05-11 12:00:00 +0000";
        location = "United States";
        "start date" = "2020-05-10 12:00:00 +0000";
        summary = "Mother's Day";
So, my SYNC fails, and I crash and burn with:
[5484 @ Tue Jul 01 10:41:22 2014] [_ISDVLog com.apple.Outlook.client.exe] SyncServices assertion failure (nil != strUTF8) in [(null) (null)], SDLogging.m:641 could not obtain UTF-8 flavor of formatted string
[5484 @ Tue Jul 01 10:41:23 2014] [YSLog com.apple.Outlook.client.exe] objcMain caught an exception:
name
NSInternalInconsistencyException
reason     : [(null)
(null)]: could not obtain UTF-8 flavor of formatted string
user info : (null)
call stack : (
Now I’m back. So, during the extract and push of the outlook calendar entries, iTunes is building formatted strings. Now, Unicode is usually 16 bit (2 characters) Unicode, sometimes called double byte code. UTF-8 is single byte, so realize you can’t squeeze 16 bits into a 8 bit byte. However, you could if the Unicode string only contained characters that were valid for the UTF-8 character set. My interpretation of the error message above was that somewhere a formatted character string contained a “non-UTF-8” character and raised the assertion. Now, my issue with the excessive detailing from the logs was that – at least with the logging parameters I had turned on – I couldn’t figure out which calendar entry caused the exception to be thrown.
First instinct was that the last calendar entry in the trace was the culprit, so I deleted that calendar entry, ran again, the sync went up to the previous entry, and threw the exception. This gives me two theories: Either the sync was processing the next entry – which wasn’t printed in the trace yet – and failed, or the sync was going back to previous records – like reviewing the buffer. In either case, the trace wasn’t helping and it was all theories.
Now what? What has everyone been saying? Issues with recurrence. And in the trace, as you see above as an example, “0 recurrence exceptions”, “reading the extended exception info (i.e. Unicode data)”.
Now, I have no clue what that means. My initial guess was that recurrence exceptions (I had non-zeros on some) was an error. But further research I realized what it could mean was that these were situations where there were recurrence exceptions. What is a recurrence exception? Suppose I want to schedule a meeting on the 4th day of the month, for every month of the year. Well, except maybe July 4th, because it is a holiday and the office is closed. I would send the meeting invite, and then a cancellation for the July 4th. (I hear there is no simple way to do this). I now have an exception because I broke the recurrence chain. Other forms of exceptions is if I keep changing the location, or the body of the invite – e.g. every month I update the agenda, but only for one recurrence, not the entire series.
So, keep in mind, that if the issue is conversion to a UTF-8 character, and it is failing, then uninstall/reinstall of anything is not going to help if the real issue at hand is the data in Outlook and is not a coding or configuration issue. Now, sometimes it is an issue, but you need to see why the syncserver tasks are failing, and may fail due to other reasons including other data issues.
So, what did I do? Well IO have 15K calendar entries, which, was taking an hour or two to slow sync (I call it a slow dance) and I was,spending days (maybe a couple of weeks) trying to fix this – and frustration was on the high end.
I removed some of my older recurrences, and changed others from never expire to like 25 maximum occurrences. No idea which one worked, or even if it was a coincidence. However, the UTF-8 error went away, and then I moved to the next issue.
Now, before we get there, with outlook 2007 finding recurrences is not difficult. Go into the calendar, and select appointment or list view (Outlook 2013 list view works ok). You can then sort on the recurrence column and see which (if any) items gave a recurrence pattern. Now maybe someone can figure out specific BAD calendar items that are throwing the exception to give us a better idea of what to look for and then report it so we can do further research.
Now, once we can get the issue out of the way, stop iTunes from throwing an exception, we are not 100% done yet. By this time what is in Outlook and on the iDevice is out of sync. We need to get that message to popup asking us if we want to merge the data between the iDevice and Outlook. This can be important if you don’t want to lose data. My issue is that with iTunes 11.2.2 for some reason won’t do it, i.e. when I select “reset sync history” it doesn’t work. At that point I was forced to rename my iTunesprefs, the syncserver folder, and a few other folders. In this case, for Windows 7 and later, the folders in “Apple Computer” of both the local and roaming paths, and I had to cancel running tasks that had those folders open. One way or another, you want the iTunes message asking if you want to merge the folders.
What can you do to help?
Report success or failures using the information above
Report if you are getting the same UTF-8 message, or if you are seeing other exceptions
Report specific cases of calendar entries that you find that you have isolated to be throwing an exception
Report any other logging/tracing parameters that you may find. It looks like you can turn on “ShouldLog” using the defaults.exe command for other tasks that iTunes runs.
This syncing issue has been going on for years, under different iTunes versions, there has to be something going on and an easier way to troubleshoot this problem. I wish I had the time, but right now I fixed the problem I had and was able to resync my Outlook with my two iPads and iPhone.
The only issue I have left at the moment is the message “the ipad xxx cannot be synced. An unknown error occurred (-54). – despite this error message, I am syncing, but the message is distracting and annoying.

Yes - both have time zone support and are set to London/GMT
The most recent of these aberrations was not even crossing a DST change - just a simple recurring event (which I've manually changed to single events by copy/paste).
I just tried a new one which goes back 1 hr 27 Oct - when UK clocks go back. As it's a dummy apt I'll leave it and see if if goes back to the correct time on 27 Oct! In the meantime, I can't afford for my appts to get screwed up so will continue to do them manually!
Thanks for your input.

Outlook 2013 crashes when collapsing shared calendar

The following issues occurs when viewing shared calendars with Outlook 2013. It occurs on multiple workstations and with multiple users.
When collapsing a shared calendar by clicking the arrow to the left of the calendar name, if one or more users of the shared calendar are selected (i.e. the box next to their name is checked), the Outlook screen will appear to refresh the screen repeatedly
whilst the cursor flashes rapidly. Outlook then crashes and has to be re-started.
The work-around is to de-select any selected users of the shared calendar before collapsing it, but we cannot reasonably expect users to remember this.
Is there a fix for this issue? Others have had the same issue (see http://community.spiceworks.com/topic/419634-outlook-2013-stops-responding-when-trying-to-collapse-a-group-of-calendars).
Running outlook in safe mode makes no difference.
Thanks

Outlook 2013 and Exchange 2007 not always syncing read status of a message

Out users are experiencing this issue from time to time. Outlook 2013 is using Exchange mailbox as default storage (Exchange 2007 SP3). Sometimes it shows that Inbox has one or few unread messages (Inbox name is bolded and there is a number near it). But
a user can't find any unread messages in the inbox. If he logs to his mailbox via OWA, then he can find those unread messages. But they are marked as read in the Outlook. So it seems Outlook 2013 has issues syncing with Exchange 2007 as we have never experienced
such issues when using Outlook 2007 with the same server.
Any hints on how to make this thing go away, other than instructing users to log via OWA and mark unread messages as read?

Hi,
Switch to Exchange Online Mode, does the issue persist?
It seems to be a sync issue between Outlook and Exchange, make sure the Internet connection is good. Let me know if the issue persist after clicking
Send/Receive All Folders button.
Try to run Scanpst.exe to repair the local data file in case the data file has been corrupted:

IPhone calendar sync issues with Outlook

I have a problem with syncing my iPhone calendar with my Outlook 2003 calendar.
For example, let's say I had a 12pm appointment today displaying both in my outlook and iPhone. However, when I sync my iPhone after the event e.g. at 3pm, the appointment entry in the Outlook is removed, whilst the appointment entry on my phone remains. I did not edit either of the appointment entries. Even if I re-sync my phone, the 12pm appointment still remains in my phone whilst it's missing in my Outlook.
Are there others encountering the same problem as well? Any ways to fix this problem? Thanks

I've talked to them. Very helpful, but no solution. The iPhone Specialist I spoke to had not heard of the problem before. At one point he put me on hold and came back to say that he had checked with some people and they had heard of this "emerging" problem but had no answers. He admitted that all problems are "emerging" problems, given that the product has been out for only 2 weeks. We tried a variety of things with no success. I had to tell him about the manual workaround - going into each appointment, setting it to recur, etc. This does make it reappear, but isn't practical for those of us with tons of appointments. I'm not shocked that they don't want to acknowledge this, given that calendar synching is so important to their targeted business customer base. It's hard to believe that they could have screwed up something that every other manufacturer seems to be able to do well and that is at the same time so critical to business users.

Exchange Outlook 2013 freezes when deleting shared calendar for employees who have been removed

Hi,
I am removing users' shared calendars from my outlook 2013 in exchange environment. The problem is, that the shared calendars belong to users who have left the company and have been removed from the domain, this is causing outlook to freeze because i think
it's trying to find the entry then delete it, rather than delete it.
There is no problem deleting a shared calendar for an user who still is in the domain. This seems to be strictly affecting users who have left the domain.

Hi,
Generally, if the shared calendar owner is removed from the Exchange environment, the shared calendar which was added before should be removed from Outlook client normally.
Please use Outlook with Exchange cached mode, and make sure the shared calendar was not added in Advanced tab in Account Settings. Please start Outlook in safe mode and remove the shared calendar to have a try.
If the issue doesn’t happen in safe mode, please disable the third-party add-ins one by one to find out the cause.

HT4528 Is there a fix for calendar sync issues between iPhone 4S and Outlook?

My boss has an iPhone 4S running iOS 6.0.1 and a Microsoft Exchange 2003 email account and has consisent sync issues with her calendar. The problem only seems to come up with calendar invitations. Usually, when people send her calendar invitations the events get added to her Outlook calendar on her PC but not on her iPhone. More recently she also sent out invitations through Outlook that also didn't appear on her phone. She has also accepted invitations on her phone that did not appear on her PC. The problem seems to have gotten worse more recently.
Does anyone know of a way to fix this? I tried deleting the calendar through the phone's settings and re-installed it but it didn't solve the issue.

There was a reported issue with Exchange and iOS with re-occuring meeting invites. Not only did it cause issues on the device, but on the Exchange server side it created huge logs and high utilization on the CAS. This was an issue on iOS 6.0.x - 6.1.3 (at which time it has been fixed from 6.1.3 on). This was attributed to the iOS version and happened on all devices (not just the 4s).
I am not sure if this is what your employee is experiencing or not - but this is one that we had, and we asked all running iOS 6 to upgrade to the most current release (oddly enough, we did not see this in iOS 5.x devices).

Users using Outlook 2013 not seeing entire public calendar.

I have two users that have same access as all other users. They can get into the public calendar but they can not see the entire calendar. They don not see anything from about the last month.
Exchange 2010 and Outlook 2013
Thanks in advance.

That sounds to me like they have a partially synchronized copy. Look to see if they've tried to synchronize the folder, and if so, delete the cache and download the content again, or switch it to be used online. Shared calendars should
generally be used online anyway to avoid ugly race conditions where users wipe each other's changes out.

Outlook calendar syncing issue with BB tour

My phone has been working great with my outlook up an till about 2 weeks ago. Desktop Manager syncs everything except my outlook calendar. I can't seem to figure out why it won't sync. I do have the newest version of the desktop mgr downloaded onto my computer.
PLEASE help!

I have provided some information below, that may help with your syncing issue.
Try going back through the synchronization options on the desktop manager. I have provided the detailed instructions below:
http://search.vzw.com/?do=viewdoc&id=16559
***Step 6 and 7 in the synchronization process will be the most important. Ensure you are selecting calendar (and anything else that is needed), as well as Outlook in Step 7. Step 8 will be up to you in whether you would like to do the following:
Two way sync
Changes are synchronized to the device and desktop application.
One way sync from Device
Changes are synchronized to the desktop application only.
One way sync to Device
Changes are synchronized to the device only.
***You may have to reset your current synchronization and set it back up. If this is needed, use the same article above and on Step 5 in the article you will have the option to reset configuration.
I hope this helps.

Outlook calendar sync issue with iphone

A friend has a desktop running XP with Outlook 2003, iTunes 10, an iPhone 3G running iOS4.
In Outlook, he has his personal contacts and calendar, both with lots of entries.
iTunes is configured to sync his contacts and calendar to his iPhone.
The contacts sync successfully - the calendar does not, meaning the calendar on his iPhone is completely blank, no entries.
We tried resetting the sync history in iTunes, creating a test appointment on both the iPhone and Outlook - nothing.
We then set up a temporary local user on the XP box, configured Outlook, launched iTunes and went to configure calendar syncing when we noticed something different.
When logged in as the temp local user account, in iTunes > iPhone > Info > Sync calendars where you have the choice between All or Selected calendars, under Selected, there was a selectable line item called Calendar.
However, when we switched back to the regular domain user account, that line item was not there.
This leads me to believe that iTunes in that domain user profile for some reason does not detect Outlook calendar, yet it does as the local user.
I thought maybe it has something to do with the user role (he was member of some custom group, not sure what the exact permissions are) and changed him to an administrator role, logged out/back in, tried again, but no difference.
I am not sure how to further troubleshoot this. What can I try to make iTunes detect the calendar? It's really puzzling because it sees the contacts in Outlook and syncs them just fine.
Any suggestions would be appreciated.

This sounds just like the problem I am having since downloading the latest version of i-Tunes. Initially i-tunes wasn't recognised so after reinstalling i-Tunes and it's 5 other associated programmes I found that there was a cmpatability isuue (Right click i-tunes icon and go to compatability tag) Once this was sorted my Outlook calendar would not sync with my i-phone. 2 weeks later I am told it is because I have Outlook 2002 and need to upgrade. Frustrating as it worked ok before the latest upgrade.

Outlook 2013 Not Responding and Offline Address Book Issues with Office 365

Around 3 months ago I setup a small business with Office 365 for email. They have 10 PCs, all running newly installed Windows 7 Professional 64-bit, eight with Office 2013 and two with Office 2010. All are connected to a local domain (Server Essentials
2012) with a single internet connection through a new TP-LINK router. Each user logs into their own PC only.
The network runs perfectly, internet connection is good but there seems to be RANDOM, INTERMITTENT issues with email not being SENT from Outlook every so often. Email will sit in the outbox for up to an hour sometimes before, eventually, being sent. Incoming
email seems ok, although this is more difficult to tell. At others times, email will be sent instantly - the size of the message and any attachments makes no difference.
The issue has happened at some point on every one of the PCs but no particular PC/user seems worse than any other. When email is stuck on one user's PC it can still be sent ok by other users at the same time - so the internet connection is not down. Users can
can always login to the OWA service ok and iPhones etc. all sync ok even when email is stuck in the Outbox.
To debug the issue I have worked on one particular user's PC and carried out the following changes -
Changes that made no difference
I have checked the router. A SPI firewall is available on the router but this is switched off.
I have changed the MTU on the router with no effect.
There are no unsual add-ins to Outlook
Outgoing email virus scanning is disabled
Outlook is NOT integrated with Lync
The OST file is around 1.7 GBytes is size.
I have recreated the Outlook profile twice but this made no difference
Switched OFF "Cached Exchange Mode" - this made things worse !
The Outlook address book is set to \Offline Global Address List
I have disabled with Windows firewall on the client PC - no change
I have adjusted the KeepAliveTime for packets in the registry of the PC to 20 minutes
Changes that reduced the frequency of "Not Responding"
I have changed the Outlook automatic Send/Receive time from 30 to 10 minutes - this seemed to help
Possible Related Problem
I have attempted to download the offline address book manually - this hangs at "Copying offline address book template file" in the Send/Receive dialog and there a NO OAB files in the data file location on the PC.
So the only measure that has so far "helped" has been the Outlook Send/Receive time change - now set to 10 minutes. Even so, Outlook will occasionally go "Not Responding" for 30 minutes or more (no windows active - only option
is to close and reopen Outlook).
There does seem to be a problem with the Offline Address book. I can download this ok for this user on my home PC (Outlook 2010) but this will not download manually on the work pc with Outlook 2013 (despite following all the debug steps above).
On work PC I can see literally hundreds of "Schannel" errors in the Windows System event logs -
Error - Event 36888 Schannel
The following fatal error was generated :10
The internal error state is 10
These errors occur every 2-4 minutes continually all the time Outlook is running. When Outlook is closed the "Schannel" errors stop !
Can anyone suggest what else to try, please ?
I have already investigated this issue on the Office 365 Community Forum, and the Outlook forum and they suggested that it was a client (i.e Outlook) issue and that I should post here for further information.
Thanks for reading !

An update to this problem.
I brought one of the office PCs back to my home network and connected it up there. With no changes to the PC I was immediately able to download the Offline Address Book without errors.
This suggests to me that there must be some problem with the internet connection or router setup in the office environment.
The router is a TP-LINK W8970. The internet connection is PPPoA. I have seen some suggestion that an SPI firewall can cause issues. This router has an SPI firewall but this feature is disabled on the router.
While investigating this issue I have frequently been connected remotely to an office PC - sometimes for up to an hour or more. During these periods I have not experienced any connection dropouts so the actual internet connection seems to be ok (i.e. it is
not dropping out).
However, something seems to be preventing the Outlook client from connecting properly with the Office 365 Exchange server in the office environment - or something is dropping the connection to Outlook. Does anyone know of any router settings that might affect
this ?
I could try changing the office router but I do not have a spare available. Can anyone suggest a reasonably low cost, currenbtly available router that they know definitely works in the Office 365 environment so that I could buy this for test purposes ?
