Hello,
Exchange 2010 SP3 and Exchange 2013 Version 15.0 (Build 913.22) Living in Co-Existence mode.
When I move a test mail box from 2010 to 2013 the outlook client continues to look for the old CAS server. IT appear recycling Exchange Application pools and/or a forced AD replication solves the issue. repadmin /syncall. I would like to have this resolved. I have thousands of mailboxes and recycling or replicating after each mailbox is moved is not acceptable. I see multiple posts on these forums that talk about the issue but none with a solid solution. Can any one point me in the right direction?
