For some reason, in our single domain, single forest setup.. we migrated some users.. 4 of them are "linked mailbox" type users.. I found an article on microsoft support to convert but it did not work (the last step): http://technet.microsoft.com/en-us/library/bb201694.aspx I would receive an error that a "resource mailbox cannot be linked to a user account from the local forest "domain.local" at line 1 char:1 Is this conversion really possible or am i missing something? (fortunately this was a test user, as i manually reassociated the account and when i opened the inbox and folders, they were empty, not good if had been a "real" user) Thanks in advance.
