Free/Busy schedul

We're using Outlook 2010 with Exchange 2010. If I create a new appointment using Outlook 2010 and add 2 users as attendees, I can see one of the user's Free/Busy schedule, but not the other user's. Instead their entire schedule is hashed out and if I place
my cursor over it, I get a message that says "No Free/Busy information could be retrieved."
Now, if I sign into OWA and repeat the above process, I can see both user's Free/Busy schedule. No issues whatsoever.
Does anyone have any idea why this is happening with Outlook 2010?

Hi,
Since OWA can work well and the user can see one attendee’s free/busy information, the issue should not be in Exchange side. Please try restarting Outlook with Outlook/ cleanfreebusy switch to clear and regenerate free/busy information
to check whether the issue persists.
Thanks,

Users complain slow when opening own calendar and Free/Busy schedule ?

Hi,
I'm using Exchange Server 2007 SP3 (no CU at all) with the following setup as VMware Virtual Machine:
Mailbox Server role (CCR enabled across two different AD sites, same domain)
PRODMBX1-VM - Production mailbox
DRMBX1-VM - Recovery mailbox
HT-CAS role (IGMP Multicast using Windows NLB)
PRODHTCAS1-VM
PRODHTCAS2-VM
DR-HTCAS1-VM
User connects to the Exchange server using CCR clustername using Outlook 2007 SP3, when the user click on the calendar tab, it works fine, but when checking on other people's calendar it takes more than 3-5 minutes with frozen display most of the times (End
task and Restart Outlook) andsomtimes the baloon pop up comes saying ("Connecting to ExcCluster01.domain.com).
Why is this happening quite so often ?
Any suggestion would be greatly appreciated.

Hi,
According to your description, I understand that the shared calendar can be opened but is synced slowly when opening other user’s calendar. Is it right? If I misunderstand, please feel free to let me know.
Does the issue happen to all users or some specific users? We can open other users’ calendar in OWA to check whether it can work well. As for Outlook users, please make sure the Outlook 2007 users are using Outlook in Exchange Cached mode and configured
correctly as the following settings:
1. Click Account Settings on the File tab.
2. In the Account Settings dialog box, click the Email tab, click to select the Exchange account, and then click
Change.
3. Click More Settings. On the Advanced tab, make sure the
Use Cached Exchange Mode and Download Shared Folders check box have been checked.
4. Finish it and restart Outlook.

Windows user - outlook - no free/busy info

Howdy,
So working with SL server. Thus far very happy with it, but running into one issue. I've got a windows user, that is using his iCal (calDave) calendar thru outlook. He is unable to see free/busy information, whereas my mac users can see it. Is this a configuration issue, or just a 'you can't get there from here' issue.
I can provide more information if it is needed.
ST

I did configure the outlook user to use the iCal service.
What I did was, login to the web server, login as the user (all of this done from end users windows machine), go to their calendar, hover over the calendar name in the upper left side of the page, and an italic 'i' will appear, click on that, and an info box for that ical account will appear. click on 'subscribe to ical' It should then give you the option of what app to open this in/for. Choose outlook. It should then give you a window of subscribe to calendar url. Now i'm not in front of a windows box right now, so am working from memory. I believe in outlook you subscribe to web calendar, and paste in the url, it should look something like this webcal://serverhostname.domainname.com:8008/calendars/_uids_/144BB4E3-35CB-4F1E-BEB9-2B20E4B6B139/calendar.
Now this should allow them to retrieve calendaring information to outlook. If you want them to push their free busy schedule back, I believe you select the account, and right click and select 'publish', that will push their availble schedule to the server.
Now this is all somewhat dependent on you having mail internal, you will have to jump thru some hoops for invite replies if you have externally support mail.
I may not have these steps in all the right order, and may have been inaccurate in my instructions, so if I am, query back and I'll try to step thru it when on a windoze host.

Outlook 2013 with Office365 exchange Scheduling assistant not retrieving free/busy information

Hi, we are using Outlook 2013 with Office365 Exchange and when using the Scheduling assistant in Outlook users are seeing "No Information. No free/busy information could be retrieved". The scheduling assistant works fine in OWA.
I have spent time trying to find an answer on the web but most answers involve different exchange variations.
Mark

Hi,
Since the problem only exists on Outlook Client, we can try running Outlook with the switch "/cleanfreebusy", this will clear and regenerate free/busy information:
outlook.exe /cleanfreebusyin the blank box, then press Enter.
You can also switch between Online and Cached Mode to check if there's a difference.

Outlook 2010 Scheduling Assistent - No free busy information can be received.

Folks:
I have recently upgraded to Outlook 2010 running on Windows 7 x64. My email is exchange based. My machine is not a member of the domain my exchange server is in.
I access it my a stored credential.
Everything is fine except for Scheduling assistant. All the folks invited to a meeting (except for myself) show up as "No Information Available".
I have found plenty of posts that suggest this is also a Outlook 2007 issue, and that creating a key HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Options\Calendar\UseLegacyFB
(value 1) solves the issue. (Example:http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/c765605d-27a7-4784-993c-925394e2e09f) I did create the key on my Outlook 2010 machine - but in HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Options\Calendar
key. It is not resolving my issue.
Does anyone know the Outlook 2010 solution to this issue? Note: I have Administrative privilege on my Client - but no privilege on the server. I need to get
Outlook 2010 to interface with Exchange 2007.
John

Hi John,
Thank you for using Outlook IT Pro Discussions forum.
From your description, I understand that you are using Outlook 2010 and Exchange account.
There is no free busy information when using scheduling assistant. If there is any misunderstanding, please feel free to let me know.
First, you must be using an Exchange server and everyone must publish their free/busy information.
Check from File > Options > Calendar Options > Free/Busy Options.
Make sure the month value for publishing is not zero.
Also, I found a similar thread here:
http://social.technet.microsoft.com/Forums/en-GB/exchangesvradmin/thread/5991f3b6-f0cc-432f-82c6-f24da0a42862
You can also try the suggestions in that thread to recreate the web services virtual directory
===============
1. Remove-WebServicesVirtualDirectory -identity "Servername\EWS (Default Web Site)" -identity "Servername\EWS (Default Web Site)"
2. IISReset –noforce
3. New-WebServicesVirtualDirectory
4. IISReset –noforce
If this problem persists, it might be related to some settings on the Exchange server side. You can also post this thread in Exchange server forum:
http://social.technet.microsoft.com/Forums/en-GB/exchangesvradmin/threads
Please take your time to try the suggestions and let me know the results at your earliest convenience. If anything is unclear or if there is anything I can do for
you, please feel free to let me know.

Outlook/Exchange - Free/Busy time is not available while scheduling

This is very similar to another earlier question "Outlook/Exchange Out-of-office unavailable" [http://answers.microsoft.com/en-us/office/forum/office_2013_release-outlook/outlook-exchange-out-of-office-unavailable/006462a8-a693-4389-b07c-6d9a27576449]:
I do not see free/busy time for scheduling, and is unable to setup Out-of-Office Auto-Reply, while I oculd see others calendar content in the Calendar view.
In theory, these problems should be already fixed by KB2850061 but I do have newer Russian Office for home and business 2013 (version 15.0.4675.1003) and those problems are still here, while KB #2850061 seems to be inapplicable.
What is the newer KB fix which is replacing 2850061 which would be working for my verison?

Hi Timur,
According to your description, I know that the OOF cannot be setup and cannot see Free/Busy information in Outlook 2013.
How is the impact, only one user or all users have this issue on Outlook client? How about in OWA?
As Martin mentioned, both of F/B and OOF are related to EWS. If you have the same issue on OWA, I'm afraid this issue related to Exchange Server side. Please try to verify the EWS setting. Also try to re-build EWS Virtural Directory for testing.
If this issue only occur on Outlook client, I suggest run Outlook under safe mode or re-create profile. I also suggest ask Outlook Forum for help, so that you can get more professional suggestions.

Inderjit

Hi Inderjit,
Does this issue occur on only one user or all users?
If only one user has this issue, I suggest performing troubleshooting on Outlook client first.
1. Please run Outlook under safe mode to avoid some AVs and add-ins.
2. Please start Outlook with "outlook.exe /cleanfreebusy".
3. Please try to re-create profile to refresh the caches.
Then please perform troubleshooting on Exchange server side.
1. This issue may occured due to mailbox corruption in the folder level.
2. Genrally we can check the mailbox property PR_FreeBUsy_NT_SECURITY_DESCRIPTOR and verify the permission.
3. I suggest re-granding the specific user permission for testing.
4. I suggest moving the sepcific user's mailbox to another database, issues will solved by itself automatically.
If all users have this issue, I suggest resetting the permission on Calendar folder and give the necessary permissions (Free Busy Time/ Free Busy Details /Full Details) via Exfolders.

[Forum FAQ] Why can't I retrieve Free/Busy information

Free/Busy information is a feature of Microsoft Outlook that allows you to see when others are free or busy so that you can efficiently schedule meetings. You can use Microsoft Outlook to publish Free/Busy information to any server
your and your coworkers have read/write access to. However, in some cases you’ll notice that you can’t retrieve Free/Busy information correctly from Outlook. You can try the below methods to troubleshoot and get the Free/Busy information again.
Since most users who often use this feature are using Exchange, all the information in this content is only based on Exchange.
General troubleshooting methods:
Method 1: Start Outlook using the ‘/cleanfreebusy’ command line switch
Method 2: Logon OWA to see if the Free/Busy information shows correctly
Method 3: Check the user’s Permission Level when only one user’s Free/Busy information can’t be displayed
Other causes
Autodiscover has not been setup correctly
Updates
Here are the detailed steps and explanation of each method and cause.
Method 1: Start Outlook using the ‘/cleanfreebusy’ command line switch
With the ‘/cleanfreebusy’ switch, it will clear and regenerate free/busy information when Outlook starts, sometimes this process fixes the problem that Free/Busy information doesn’t display correctly, and this is always the first thing we should try when
we can’t get the Free/Busy information from Outlook.
This switch can only be used when you are able to connect to your Microsoft Exchange server.
To start Outlook using the switch, we can press Win Key +
R to start Run, type ‘outlook.exe /cleanfreebusy’ in the blank box, then press
Enter.
Please note since Outlook 2013 only uses the availability service which is connected to Autodiscover, the command line switch ‘/cleanfreebusy’ has been removed as well as the associated code so that Outlook 2013 will not recognize this
command.
Method 2: Logon OWA to see if the Free/Busy information shows correctly
If you are using Cached Exchange Mode in Outlook and having trouble getting the Free/Busy information, please logon OWA, or switch to Online Mode to see if the Free/Busy information shows correctly.
If the Free/Busy information shows correctly on OWA or in Online Mode, this problem may be caused by the Outlook Data File(.ost) corruption, which leads to the sync failure. Therefore we should exist Outlook, browse to the Data File and rename it to “.old”.
The next time Outlook starts, it will regenerate a Data File to sync and we can check if the Free/Busy information can be retrieved.
The location of the Data File can be found from File tab ->
Account Settings -> Account Settings ->
Data Files tab. (Outlook 2010 and Outlook 2013)
Or Tools menu -> Options ->
Mail Setup tab -> E-mail Account -> Account Settings window ->
Data Files tab. (Outlook 2007)
If on OWA it displays fine but doesn’t show the information correctly in neither Cached Exchange Mode nor Online Mode, it may be caused by the firewall or anti-virus settings, disable them to verify if they caused the problem.
Method 3: Check the user’s Permission Level when only one user’s Free/Busy information can’t be displayed
When a user has set his Calendar Permission to None, other people will not be able to see his Free/Busy information. When we notice that we can get most people’s Free/Busy information but fail to get one specific person’s, please consider
to check his Calendar Permission:
In that user’s Outlook, right click on his default Calendar, click Properties, select
Permissions tab.
We need to at least switch the Permission to Free/Busy time to get his Free/Busy information correctly.
Other cause 1: Autodiscover has not been setup correctly
From Outlook 2007, Outlook uses Autodiscover to get the Free/Busy information. Once Autodiscover has not been configured properly, the Free/Busy information may not display correctly. If you are also seeing issues with Out of Office assistant, we may assume
that you haven’t correctly setup Autodiscover, since these two symptoms are common when Autodiscover is not configured correctly.
To verify that, please test Outlook Autodiscover Connectivity:
http://technet.microsoft.com/en-us/library/bb123573.aspx
We can also learn Configure Exchange Services for the Autodiscover Service from:
http://technet.microsoft.com/en-us/library/bb201695.aspx
Since Autodiscover Service is more Exchange related, we need to seek Exchange support and post the question in Exchange forum:
http://social.technet.microsoft.com/Forums/exchange/en-US/home?category=exchangeserver
Other cause 2: Updates
Although Updates from Microsoft do no harm to the system for most of the time, the updates sometimes can mess things up.
Outlook 2013 November 2013 security update once became the culprit that caused some users not able to retrieve Free/Busy information from calendar scheduling. This occurs because Autodiscover fails for Exchange 2007 configurations. So in fact, this also
refers to the previous reason, Autodiscover is corrupted.
The fix for the issue above has been released:
http://support.microsoft.com/kb/2850061/en-us
Once you have some issues after updating and doubt it’s an update issue, you can always come to our forum to ask if there’s a recent update which causes the problem, we will be happy to support you. If a fix hasn’t been released yet, we suggest you uninstall
the suspicious ones from Control Panel -> Programs and Features ->
View installed updates to verify which caused the problem, also as a workaround.
Summary
The reason that we can’t get the correct Free/Busy information can vary. If you find it doesn’t work even after several general troubleshooting steps, please consider it’s Autodiscover related. For anyone who comes up against the issue that Free/Busy information
can’t be retrieved, please feel free to visit Outlook IT Pro Discussions from the URL:

All free/busy requests get error 403 in iCal with MobileMe

I'm playing for the first time with looking with my availability in iCal / Lion / MobileMe CalDAV accounts.
Everything else is working well with my calendars and Mobile Me.
I can add events, remove them, edit them, the sync is working well between the web interface and iCal on my Mac (10.7)
The only thing amiss is the availability window just logs an error to the console after a short time out.
It's error 403 which seems to be a permission denied error.
Do I need to grant permission for MobileMe to publish my free/busy status anywhere?
It it locked down until I allow sharing?
Is it tied to sharing a calendar some how?
Just sending a call out to others in case I'm missing something obvious. There are instances of this error on the boards with iCal and 10.6.6. so I presume it's more a server setup / service interruption than something I can change.
Thanks for any input - even if it's a "it works for me right now" or "I too can't get mobile me status in iCal"
(p.s. Mobile Me support says they can't help - talk with iCal people.)
(p.s. After two hours on the phone with iCal - it's back to the MobileMe people to try again. I figured I'd give a shout here before I try them again...)
Here's the error message from /private/var/log/system.log

I have a similar issue. My girlfriend is using a yahoo address and for the life of me I cannot send her an iCal invite from my me.com or mac.com address. It never shows up in her email, not in inbox, not in junk, not deleted. I get an exclamation point on her name in the iCal invite. I can send her invites from Gmail. I created a test account on yahoo and I can send invites to that test account.
Of course I can email her just fine. I can open the invite in iCal, select the down arrow on her name and select "send email" that works just fine. I try to "invite again" and nothing... this is maddening
I've deleted iCal cache, deleted her contact, tried just using her smtp yahoo address, i don't have this issue with anyone else that I know of...

Calander Free\Busy Issue

Hi all,
We have Exchange 2010 and users are working with office 2007.
I have not checked all users, but those who i checked (about 10 out of 300), can see the details of other users appointments who are invited when the enter the "Scheduling Assistant".
I checked the calendar Free\Busy permissions and they are set to:"Default - Free\Busy Only".
There are no other permissions to other users.
This issue is very important since the sensitivity of a lot of appointments, especially of managers is high.
Thanks in advance.

Hi Hasin,
Thanks for the reply.
I checked the permissions from the outlook side.
I tried the command on the CEO mailbox and i received an error message (I replaced here the user name with xxxxx for security reason):
Cannot process argument transformation on parameter 'Identity'. Cannot convert value "xxxxx:calendar" to type "Microso
ft.Exchange.Configuration.Tasks.MailboxFolderIdParameter". Error: "The mailbox folder identity "xxxxx:calendar" isn't
in the correct format. The correct format should look like this: "<MailboxIdentity>:<FolderPath>". "
    + CategoryInfo          : InvalidData: (:) [Get-MailboxFolderPermission], ParameterBindin...mationException
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,Get-MailboxFolderPermission
Then i tried to write down "calendar" in Hebrew (which is our native language) and i get only question marks (I guess that Power Shell dont like my language). I have succeeded to do it on several users, i guess because their Outlook is in English
and the result was:
FolderName   : Calendar
User         : Default
AccessRights : {AvailabilityOnly}
Identity     : Default
IsValid      : True
As i understand according to the result, people should only see if the user is available and it's not the case. Users can see the full details.

Free Busy information not appearing correctly in Outlook

First some background:
For two of our Resource Mailboxes, we are having an issue where all times are showing outside of Work Hours (gray). The working hours for both of these rooms are set for 8-5, pst, just like all our other Resource Calendars. This occurs on all installed Outlook clients,
but does not occur through OWA (both logged in as the resource, and a standard user).
Things we've checked and confirmed are the same with a working resource:
Permissions for the Mailbox
Permissions for the Calendar
TimeZone Information
Work Week Information
Resource Policies
Steps we've taken to try and resolve the issue without affect:
Forcing a OAB update on Exchange and Locally
Changing Work Week/TimeZone
Changing Calendar share permissions
I'm a little lost at where to proceed next, I've got a mind to try and just kill our OAB and rebuild from scratch, but will talk that over with our Exchange Admin. I've done Compares on Get-Mailbox, Get-MailboxCalendarConfiguration, Get-MailboxCalendarFolder,
Get-MailboxFolder, Get-MailboxFolderPermission, Get-MailboxRegionalConfiguration and probably every other cmdlet one could run on a mailbox (except for probably exact the one I need).

Hi,
Do you mean the issue doesn’t happen when users view room’s free/busy information from Scheduling Assistant in OWA?
Please make sure the date and time zone are the same in Exchange server, Outlook clients settings, user local machines and Domain Controller. Also double confirm the work hours for these two room mailboxes are configured the same for 8:00AM to 5:00PM. Please
run the following command in Exchange server to check the calendar processing for these two problematic room mailboxes:
Get-CalendarProcessing Room1 | FL
Get-CalendarProcessing Room2 | FL

Entourage 2008 & iCal sync inaccurate free / busy status for events

On a campus using Exchange 2007, I am using Entourage 2008 and sync to iCal 3.0.2 (Leopard) via Sync Services in Entourage's preferences. Both Exchange 2007 and Entourage 2008 have only been installed in the last two months.
I have found that events which I mark as "free" in Entourage 2008 are changed to "busy" after a sync with iCal. The free / busy status is correct when the sync with Exchange takes place, but the status is incorrectly changed to busy every time the iCal sync takes place.
I need to put campus events, co-worker planned absences, and similar things on my calendar, but these items need to remain as "free" so that I can be scheduled during those times. This all worked correctly with Entourage 2004 and the older version of Exchange.
Does anyone know how to correct this behavior so that the free / busy status is not changed with a sync to iCal?

Sue,
Wish I could offer some good advice, but the easy syncing of iCal and Entourage 2008 so far has been impossible if not a nightmare.
When you go to import in Entourage and iCal is NOT listed as "another application", we are in HUGE trouble.
A real shame that in today's world of "New Media" and PDA's like iPhones and Blackberry that the two billionaires from Apple and MS did not provide us with easy and simple export/import/sync tools.
Maybe they should rename Office 2008 to Office 1984

Free/Busy availability and Out of Office not working after Exchange 2003 to Exchange 2010

We just migrated from Exchange 2003 to Exchange 2010 as an intermediate step before we get to Exchange 2013. I want to make sure everything is working OK before we start the migration to Exchange 2013.
The users have Outlook 2010, and there are 2 issues. They can't view free/busy times for other people using the scheduling assistant, and they can't set their Out of Office messages. If they go in through Outlook Web Access, then these features
work!
I've searched the forums, and I see a few similar issues, but I don't think this is related to the .Net issue on the CAS server.
Any suggestions?
Thanks!
--Kent

Hi Kent,
Try checking the free busy info Outlook 2010 with running /cleanfreebusy switch
Check the Free/Busy System Public Folder and pointed out to the correct server on each mailbox DB in Exchange 2010
Find the public folder replica database
get-publicfolder -Identity "\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY" -Recurse | fl name,Replicas
In E2k10 check if the exchange 2003 is added in the replica list. If not try adding them and check.
force Public folder content replication.

Free Busy takes over 30 seconds to retrieve on Outlook 2010 using Exchange Server 2010

We have a small 100 user domain running Exchange server 2010 and outlook 2010 clients. The issue is that Retrieving Free/Busy takes over 30 seconds.
So someone is trying to schedule a meeting has to wait Minutes see the Free/busy time for many users.. I have checked and all the users in question have published at least one month free busy time.
It seems it would be much faster. Anyone have this same experience and know of a way to speed it up?
thanks in Advance
David

Hi David,
Does the issue happen in OWA? In Exchange 2010, the free/busy information is retreved by using Availability service (EWS url). Generally, if a user wants to view free/busy information when create a meeting, the http Availability service request
would send to CAS server.
Please check whether the usage in Exchange server is high when the slow free/busy information occurs. This reflect time would also be related to the network in your environment.

Exchange/Outlook 2013 No free/busy information could be retrieved

We are getting a problem for certain users where their Free/Busy info is not visible in the Scheduling Assistant.
HOWEVER - the same user's calendar can be viewed as a Shared Calendar without a problem.
I believe this has been working previously and has now stopped.
It is affecting Mac & PC user the same and is also apparent in OWA.
Please help as typically this is affecting our VIPs.
Thanks

Hi,
According to your description, I noticed that the free/busy information also couldn’t be retrieved in OWA. Please confirm your Exchange version and double check whether all users can’t use scheduling assistant to view free/busy information.
In Outlook client, please run Test E-mail AutoConfiguration tool to test the Autodiscover service and Availability service URL:
please open Outlook - press CTRL key - right click on the Outlook icon from right bottom corner taskbar - Test Email AutoConfiguration. Put your email address - uncheck use guessmart and secure guessmart authentication - click Test to check your Autodiscover
service.
In Results tab, please get the Availability service URL. Then access it in Internet Explorer in your local machine, and check whether a proper XML file can be returned.
