Hello,
We followed this blog post to migrate from Exchange 2007 to Exchange 2013:
http://blogs.technet.com/b/meamcs/archive/2013/07/25/part-1-step-by-step-exchange-2007-to-2013-migration.aspx
Before decommissioning Exchange 2007, we created a new user on the Exchange 2013 server using ECP and migrated an existing Exchange 2007 user using ECP.
Autodiscovery, Outlook Web Access and Active Sync are working fine.
However, we cannot open these two mailboxes in Outlook 2010 or 2013 on Windows 7.
When I add one of the mailboxes in Outlook, AutoDiscovery is working fine. However, Outlook then complains that "the action cannot be completed. the microsoft exchange address book was unable to log on to exchange."
When I do the same in Outlook with a user that is not yet migrated, the Mailbox is setup just fine.
Any idea?
Best regards,
Florian
