Thanks guys but I have Googled all this myself. I was hoping for a little more insight to what is going on and hopefully your experience.

I can see that; Setup.com /PrepareAD will recreate them but what if they already exist in AD but the mailboxes do not? Are there any risks?

If I removed the Arbitration mailboxes what impact would it make on my enviroment?

ASKER

Additionally, running; Setup.com /PrepareAD

Is it safe to run in a production enviroment?

There should be no issues running the prepareAD command as it can be run anytime without any issues

We have 4 Exchange servers in the DAG. Does it matter what server I run prepareAD on? Or does it need to be run on the Hub Tranport servers only?

So to confirm. I can run; Setup.com /PrepareAD at anytimeand it will not affect anything else?

Should I remove the existing Arbitration mailboxes before I run PrepareAD ? Or doesn't it matter?

I have performed Setup.com /PrepareAD and it completed successfully however the arbitration SystemMailbox still exists on the old server?

No change, any ideas?

I manually deleted the account and followed these instructions; http://msundis.wordpress.com/2010/08/17/recreate-and-enabled-missing-arbitration-user-accounts-and-mailboxes/

All perfect :)

1) Is it safe to delete the Arbitration mailboxes? - Move it

Move:
Get-Mailbox -Arbitration -Database db1 | New-MoveRequest -TargetDatabase db2

Disable:
Get-Mailbox -Arbitration -Database db1 | Disable-Mailbox -Arbitration

Remove:
Get-Mailbox -Arbitration -Database db1 | Remove-Mailbox -Arbitration -RemoveLastArbitrationMailboxAllowed

New Arbitration Mailbox:
New-Mailbox -Arbitration -Database db1

I saw one more command on the internet
Remove-Mailbox <Mailbox ID> -Arbitration -RemoveLastArbitrationMailboxAllowed

Hi Rancy, I couldn't move it as it sat on a Exchange server that no longer exists. Removing it manually from AD worked.
