What are arbitration mailboxes in Exchange 2010 / 2013

Arbitration mailboxes are a special type of mailbox that are created initially when deploying the schema (/PrepareAD.) There purpose is too typically be used internally by Exchange and provide organizational wide data within them such as:

- Global Address Book Data (Only in Exchange 2013+)
- Unified Messaging Data
- Message Moderation Operations

You can easily query them with:

Get-Mailbox -Arbitration

Typically you should never have to manually touch these inboxes - unless something is serious wrong e.g. accidental deletion of them!
