Greetings, community!)
I try to Upgrade our Exchange 2007 to Exchange 2013SP1 and have a little troubles:
On the step where we migrate test users from Exchange 2007 to Exchange 2013 MailboxDatabases, when users open Outlook 2013/2010/2007 they asked for password. But if they cancel this window, mailflow work fine.
But they have troubles with Publick Folders (they are still on EX2007) and other users calendar access.
I set all internal outlookanywhere auth methods to NTLM, and check CAS IIS settings with that page: http://technet.microsoft.com/en-us/library/gg247612(v=exchg.150).aspx
If I disable Outlook cached mode, Outlooks works fine.
What could be?
