Good Afternoon all,
I am currently in a coexistence environment Exchange 2010 Migrating to exchange 2013. I have made all the necessary configuration and now users are connected to 2013 CAS and proxy back to the 2010 Cas. So far so good.
The problem is when I migrate a mailbox from the 2010 to the 2013 something is not going according to plan.
The migration is completed successfully. Outlook will display the message "your administrator made a change ........" so far so good.
But then after closing and reopen outlook an error message saying outlook cannot display the set of folders is presented.
Strangely enough logging to the user mailbox via OWA, instead of the nice new 2013 interface you get the yellow old 2010 interface. So it seems as if the mailbox was not actually moved.
To make it more interesting in both 2010 EMS and 2013 the mailbox location shows as if the mailbox has been moved.
SO to recap.
User is on 2010.
Migration process initialised and completed.
User get notification to close and reopen outlook after the migration.
Outlook cannot open set of folders.
OWA present mailbox in 2010 interface.
EMS shows mailbox is located in the new 2013 DB.
Anyone seen anything like that?
P.S - if a new user is crated on the 2013, everything ticks along just fine.
