I have two users who had their mailbox database (storage group) moved on Exchange. Now they are getting all their messages in UMR mode. Dohprop says the Mailbox is unavailable, but I don't see a decent log anywhere else expressing this.
How can I modify an existing user to get attached to their new mailbox storage group (database).
You should only need to re-run Permissions Wizard making sure you select the new mail stores, which will grant access to our MsgStoreSvc account.
