I have introduced Exchange 2013 into an Exchange 2007 environment.
After a mailbox is moved from Exchange 2007 to Exchange 2013 everything works as expected except users receive
"The action cannot be completed" error in Outlook 2010 when they clickFile > Account Settings > Change
After acknowledging this error, any shared mailboxes are not listed (this also happens if users have no shared mailboxes)
Creating a new profile resolves this issue - this is impractical however
Does anyone know how to prevent this issue?
