Place a Mailbox on Retention Hold
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
Placing a mailbox on retention hold suspends the processing of a retention policy or managed folder mailbox policy for that mailbox. Retention hold is designed for scenarios such as a user being on vacation or away temporarily.
During retention hold, users can log on to their mailbox and change or delete items. When you perform a mailbox search, deleted items that are past the deleted item retention period aren't returned in search results. To make sure items changed or deleted by users are preserved in legal hold scenarios, you must place a mailbox on legal hold. For more information, see Place a Mailbox on Litigation Hold.
You can also include retention comments for mailboxes you place on retention hold. The comments are displayed in supported versions of Microsoft Outlook.
