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!

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.

Please mark as helpful if you find my contribution useful or as an answer if it does answer your question.

That will encourage me - and others - to take time out to help you.

There wasn't a replica for the get-publicfolder command for schedule/free busy.  Would that be the reason?

Thanks!

One additional piece of information - All users that have Outlook installed on their local machines (laptop/desktop) are having this issue.  There is a Citrix server with the same version of Outlook and if you login to Citrix it is working fine.

Any ideas?

Hi Kent,

I suggest running "Test E-mail AutoConfiguration" on Outlook, if there is anything abnormal, please post the result.

Thanks
