We fresh installed Exchange Server 2013 on a new Windows Server 2012. For the Out of Office Assistant, OWA works well, and Outlook 2010 works too. But when we try to start the OOF from Outlook 2007, we got the following message:
"Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later"
This error happens to all Outlook 2007 users, no matter whether they are connected in LAN or through internet. We also notice that the Scheduling Assistant is the same situation in that it works on OWA and Outlook 2010, but not 2007.
Our users computers are not registered or controlled by the Windows server.
Could someone help us out of the issue?
Thanks a lot!
