I think I did it again
I made you upset, your mailbox is gone
It might seem like a rush
But it doesn't mean that I'm oblivious
'Cause to lose all your emails
That is just so frustrating
Oh Exchange, baby
Oops!...I did it again
I played with your mail, got lost in the shame
Oh Exchange, baby
Oops!...You think I’m the IT shiz
That I'm sent from below
I'm not that incompetent
From time to time I run across a situation where an Admin has been a little overzealous and has either deleted the AD account for the user or disconnected the mailbox. Sometimes they create a new mailbox and call it "Macaroni" but that's like sewing a plaid sleeve on a polyester suit. Sure, it's a sleeve, but take a look in the mirror.
The other situation is when a user is "moved" between domains in the same forest. By "moved", I mean "deleted and then a new account created" in the new domain. The major issue with that is, the LegacyExchangeDN will be gone if you simply recreate the mailbox and the user won't have any items from the previous mailbox. Yes, you can have the user export their mailbox to PST before this action is done, but there's no guarantee that they grabbed everything. I've seen it happen where they grab the Inbox, but forget the Calendar or Contacts.
My solutionA script that will either Reconnect the previous mailbox to the AD account OR perform a restore from the previous mailbox to the new one.
The basics of my script
- Grabs the AD User object for restoration purposes
- Searches each mailbox server in the environment for the disconnected mailbox of the user
- If the AD User has a mailbox
- A New-MailboxRestoreRequest is performed to restore the items from the disconnected mailbox to the new mailbox.
- The disconnected mailbox's LegacyExchangeDN is added to the new mailbox as a X500 address.
- If the AD User does not have a mailbox,
- The latest disconnected mailbox is connected to the AD User
Here’s the script (Relink-Mailbox.ps1) - Download
- The mailbox alias, SamAccountName, or GUID. This should be as unique as possible.
- Prevents the script from automatically running the Clean-MailboxDatabase cmdlet
