Outlook client remains disconnected after the mailbox is migrated to Exchange Server 2013
Assume that you migrate a mailbox from Microsoft Exchange Server 2010 to Exchange Server 2013. However, the Outlook client remains disconnected for about 1–2 hours after the mailbox is successfully migrated.
Afterward, the client connects automatically without the need for any changes.
Note If you recycle the Exchange Server 2013 AutoDiscover Application Pool right after the move is complete, Outlook connects as expected.
This issue occurs because of the AutoDiscover application pool database cache refresh interval is 24 hours.
Note After you apply this cumulative update, the database cache interval is set to 1 hour by default.
To resolve this issue, install Cumulative Update 13 for Exchange Server 2013 or a later cumulative update for Exchange Server 2013
To work around this issue, recycle the Exchange 2013 AutoDiscover Application Pool right after you migrate the mailbox.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
