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
Exchange and BES are installed and running on different servers
OS of the server running BES 4.1 is WINDOWS 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 Calendar Sync Issue "Microsoft Office Outlook Offline Folders"

I am experiencing an issue synchronizing my Outlook Calendar with my iPhone. I am using the latest version of Itunes (7.6.2.9).
To reproduce:
1) Sync Outlook calendar with Iphone.
In Outlook, the following error displays:
"Microsoft Office Outlook Offline Folders"
"The file C:\Documents and Settings\<name>\Local Settings\Application Data\microsoft\outlook\outlook.ost is in use and could not be accessed. Close any application that is using the file, and then try again."
At this point, in order to view any mail or calendar entries, I am required to reboot my computer and relaunch Outlook. I had to disable synchronization with the iphone.
I followed the troubleshooting Calendars hints from the Support site, and I clicked "Reset Sync History." This seems to have temporarily fixed the problem, but I am not confident I won't receive the error again.
Is there a permanent fix for this?

This may be more than a temporary fix, so I would wait and cross that bridge if and when the same error message turns up.

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 Calendar Sync Frustration

Ok....I've done it all. I've reinstalled....numerous times...earlier iTunes versions...operating systems...reduced my pst files to less than five appointments, none of which are recurring...rebuilt pst files....you name it, I've done it. My Outlook calendar still does not sync with iPhone/iTunes. I get the "outlooksyncclient.exe" has encountered a problem and needs to close..." error message. I'm inclined to subscribe to the point of view I saw from one poster that PocketMirror/Palm figured it out, Apple should be able to as well.
What really appears to be happening is that one of the two add-ins that iTunes/iPhone requires isn't being loaded. According to Apple documentation, you need "iTunes Outlook" and "Outlook iTunes Sync" add-ins. I only get the iTunes Outlook" add-in from iTunes, no matter what version I install, reinstall, deinstall, reinstall, etc. One would think that if "syncing" is the problem, you'd want to get that second "Outlook iTunes Sync" add-in loaded and seen by the OS, no?
Even when I was with a VERY good tech at the local Apple store, he didn't want to touch the issue that the add-in wasn't being loaded. To be fair, he saw it on the computer (haven't been able to locate it myself, but I saw it when he ran a registry list), but somehow it's either not being activated OR seen by iTunes. Seems to be a key player here, but the tech could only report the issue to tech support...leaving me in the dark since there is no way to follow up on the progress of the report to tech support.
Am I alone here? For a smart phone/PDA, not syncing with what is probably the most used corporate contact management software's calendar is, well, not very smart (especially right out of the gate on this cutting edge tool).
I'm not complaining about the phone features. It's LEAGUES above any phone I've seen. Having an iPod on board is just bonus. The Map widget is great too, especially linked in with the contacts (...which, by the way, seems to sync fine with Outlook...). But come on...if you can pull all that off, what's up with not being able to do the calendar? Want to lose the majority of sales folks out there that could truly benefit from this product? No sweat, just don't put a priority on fixing this Outlook calendar sync issue.
I'm posting this because I have a feeling that if I don't, and no one else voices this opinion, it won't be addressed....and this would be a shame since this product has so much immense potential.

Try this. Forgive me as I am not at my work computer but expericenced exactly the same problems.
Go to edit your email account and assuming you are using outlook 2003 since I don't 2007 you will need to find the dialog box that says something to the effect of send your information to your personal documents. It is a drop down menu within settings. You will then need to close outlook and open it again. Try syncing your iphone and this worked like a charm for me.
To sum it up your mail,contacts, and calendar entries are curetnly being stored on your work server. Iphone doesn't like that. When you tell outlook to store these items on your personal documents they then are stored on your hard drive and Iphone loves that. When I first tried doing this I noticed that I didn't have the option to send these items to my persnal files so if that is the case for you you will need to create it by clicking add and just pointing to personal files.
I hope this helps.

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.

Major problems with iPhone 4 & iPad 2 both 5.1.1. - Outlook Calendar sync

Folks, really need some help here, being forced to revert to Blackberry Bold 9000 because of issues with Outlook Calendar sync since 5.1.1 upgrade on both my iPhone & iPad. Our company Enterprise Active Sync server is 2003 (please don't mention upgrade - already a seperate conversation byt all costs).
email sync's fine on both devices, plus i can continue to use both iCloud accounts, and BT yahoo mail etc !
national holidays set up in Outlook calendar come across, as does some calendar items, but then falls into a resync mode with nothing staying in the device, i can also see and read calendar invites, but once accepted, they disappear !
Searching the internet suggests I'm not alone with this issue - any ideas welcome, seems not to be a problem on os 4 !!! but A) I don't know how to regress and B) why should I ?
Many thanks in advance, please don't make me go back to a BB !!!
Finally, I've been using the devices without issue for nearly 2 years - so again it's linked to 5.1.1. upgrade !

Hi Tim
Firstly, apologies for the slow response to your very quick reply !
I've checked back, we're using Exchange 2007.
We've actually got a ticket open with Apple at present, so anticipate that a patch may be available.
It is still curious though that out of a 200 user community trialling our internal iPhone & iPad pilot, we only have 2 issues (mine and a colleagues), however anticipate that there will be more issues as nearly entire community is on 5.1.1.
On a second point, any ideas how one can rollback to 4.3.3 on an iPhone or iPad ? I can't find anything that implies a self rollback without jail breaking the device ?
Thanks again for the help.
Marc

Outlook Calendar Sync has stopped working

Prior to iTunes 7.4.X, Outlook Calendar Sync was working OK.
Now, it does not. No new calendar entries posted in Outlook following the installation of iTunes 7.4.X make it into the iPhone.
I've tried all the usual tricks - reinstall iTunes, reset the iPhone, nothing helps.
Any ideas out there?

hi, thanks, i tried that as described here in the troubleshooting faq - no improvement.
http://docs.info.apple.com/article.html?artnum=305845
here's what i noticed however, there's not a second add-in as described in the doc. the Outlook iTunes Sync add-in is missing on the system entirely. after re-installing, iTunes, it's still not there and so can't be added through browsing to the iTunes dir and therefore i can't select it.
where can you get this second add-in? also following these instructions, i deselected the microsoft outlook mobile service add-in which sounds like it might be needed. ??
thanks for any help.

Outlook and iPhone Calendar Sync Issue

I’m having an issue where any meeting on my Outlook calendar that is after 3AM and spans multiple days (i.e meeting is from Sunday 4AM to Monday 6PM) it actually shows up on my phone as being Monday-Tuesday instead of Sunday-Monday.
Has anyone else seen this?

We have had this same issue on the older through to the latest os. I dont know whether the issue is the iphone diary or outlook.
We have 2 phones syncing to one outlook account. If I put in an all day event on my iphone when it syncs to outlook it spans 2 days and then when synced back to the phone it honors this, so suddenly I have no idea which day the event is on.

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
Steve Preston

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 2010 Calendar Sync Issue

Background:
1. Traditional Chinese Windows 7 Ultimate 64bit running Outlook 2010 64 bit and iTunes 10.6.3.25 64bit.
2. Three apple devices (namely, one iPad 2, one iPhone 4S and one iPhone 4) using the same apple id sync contact and calenda with Outlook 2010 since Day 1.
3. No setup for sync with iCloud, Google Calenda, Live Calenda,etc before.
Issue:
1. Calendar and contact sync were working perfectly until two weeks ago when a conflict calendar message appeared but I neglected it (and now the conflict message does not pop up again).
2. Any edit/ new addition in iDevice calendar does not appear in Outlook Calenda after sync. Any edit/ new addition in Outlook Calendar does not appear in iDevice either. But contact sync is working flawlessly.
3. Although the new entry/ edits of calenda of iDevice, say iPad 2, does not appear in Outlook Calendar after sync, the (supposingly) missing items appears again in my iPhone 4S and iPhone 4 after sync with Outlook. So I believe the items are still there but cannot be properly displayed in Outlook Calendar only. But if I create an entry in Outlook Calendar, the new entry or edit do not sync to my iDevices.
4. Tried "reset sync history" and it didn't resolve the issue. Browsing in internet for three days and tried many methods but the issue still exists. Checked the calendar profile in Outlook and it is teh same as contact prfile. But contact sync successfully but calendar does not.
Please HELP!

Exatcly the same thing here with Outlook 2007 (-> not an Outlook 2010 issue???)
I tried several times. First I deleted all entries in my Outlook (I only want to copy entries from iPhone to Outlook). I made sure, none of the "Replace information on this iPhone"-flag was ticked and I also used the "Reset Sync History"-Button in iTunes.
Sync is OK for Contacts and Notes but all Calendar-Entries are deleted on the iPhone after sync (and Calendar in Outlook is still empty of course).
I am using an iPhone 3GS with iOS 4.0.1, iTunes 9.2.1.4, on a Win7 64Bit with Outlook 2007 (was all OK a month ago when I was still using iOS 3.1.3, and iTunes ?.?.? (not sure but I think it was the version just before 9.2))
BTW: We are not allone. See following link:

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).

Outlook/ IPhone calendar syncing issue - adding one hr to EST.

Is there a fix for syncing Outlook 2003 calendar and the IPhone 4s? It continues to add 1 hour to the phone calendar - I have synced it both ways with the Time Zone Support on and off still no change...this is getting frustrating...any help?

I am having this problem also. It happens with re-occuring events. The Outlook calendar is correct but the iPhone calendar is changing the events by one hour. I have tried the fixes suggested elswehere regarding changing / setting the timezones but as the OP stated this is not fixing the problem.
Apple please address this.
