This is useful in many different scenarios such as:

• Simplifies the help desk role of creating new mailboxes by removing the need for help desk staff to choose an appropriate mailbox database
• During bulk mailbox provisioning or mailbox migrations the mailboxes are automatically spread over all available mailbox databases

Despite the benefits there are also situations in which the Exchange administrator would not want mailboxes automatically provisioned on a particular database.  For example a mailbox database that is configured with a very large mailbox storage quota for VIP users should be excluded, or a new mailbox database that is still in the process of being configured for use should be excluded.

To exclude a specific Exchange Server 2010 mailbox database from automatic provisioning use the following command in the Exchange Management Shell.

C:\>Set-MailboxDatabase -Identity "Mailbox Database 04" -IsExcludedFromProvisioning $false
