I am running into an issue. I suspect a user mailbox that is shared by other users got corrupted.
All the internal users are unable to send on behalf this problematic mailbox and send as. I did check permissions and the users has rights to send as and to send on behalf. In addition to this, i was looking at the full access permissions on this shared mailbox, and for some reason i cannot remove a single users that has full access to the shared mailbox
So, I need to know how to repair a corrupted mailbox using PFDVAdmin or another MS tool,
Should I migrate the mailbox to another DB?
How to deal with corrupted mailboxes on Exchange 2010 SP3?
