Create a Discovery Mailbox
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
Microsoft Exchange Server 2010 Setup creates a Discovery mailbox by default. Discovery mailboxes are available as target mailboxes for discovery searches in the Exchange Control Panel. You can create additional Discovery mailboxes as required. A Discovery mailbox can't be repurposed or converted to another type of mailbox. You can remove a Discovery mailbox using the same procedure used to remove other types of mailboxes.
By default, Discovery mailboxes have a mailbox storage quota of 50 gigabytes (GB). Although you can increase this quota, Discovery mailboxes larger than 50 GB are not supported.
Warning
After a discovery search is completed, the Discovery mailbox used as a target mailbox for the search can potentially contain sensitive information. You should control access to Discovery mailboxes and ensure only authorized persons have access to them.
