I migrated a couple of mailboxes from Exchange 2010 to 2013 (co-existing in the same forest).
All mailboxes work and can be connected to via OWA. But when trying to connect a specific mailbox in outlook, it cannot be connected. That is, when clicking Check Name, the specific mailbox doesn't show up, while other (test) mailboxes do. What can be the reason of this?
I'm sure I have full access on this mailbox.
The mailboxes that aren't working are in a differen (global) address book. I have a vague idea this can be the issue in this case...
