I've deleted a few mailboxes accidently. I have been trying to restore them from last night's backup (using the Recover Deleted Account tool in the Admin console).
Any users without spaces in their name recover successfully, but all the ones with spaces (most of them) in the Name field won't - you select them, click ok and no user is selected. FOund TID 3989266 which says users with a space in the Mailbox ID can't be recovered, you need to remove the space first. Any idea how I can do that or another way to restore the mailboxes?
