We are running Exchange 2010 in our environment and client machines running Outlook 2010.
We have shared multiple mailboxes using Full Access and Send As permissions for specific users, however the automapping doesn't work and comes up with error shown in picture. "the set of folders cannot be opened"
Strangely enough, if I add mailboxes manually to the profile itself, then I can access the shared mailbox just fine. I have read some articles on technet that you can use Exchange Shell to disable automapping, however, we just want auto-mapping of mailboxes to just work without any errors.
