After you install a new Exchange 2010 server for mailbox role, it created a default mailbox database with some database ID as suffix.
The name of the database could be something as “Mailbox Database 1514210160”.
This default database contains Arbitration Mailboxes which are not directly visible through Exchange Management Console. The arbitration mailbox is used to store the original message that’s awaiting approval.
By default, one arbitration mailbox is created for moderated transport during setup. It’s used for all moderated recipients.
The list of Arbitration Mailboxes is:
· Microsoft Exchange Approval Assistant
· Microsoft Exchange
· Discovery Search Mailbox
· Microsoft Exchange Federation Mailbox
In case you want to remove this default mailbox database, you will need to first move the arbitration mailboxes to another database and this has to be done through EMS.
I hope the above screenshot is self-explanatory and easy to understand. Please let me know through comments if walkthrough guide is required.
