When an organization is dealing with the possibility of legal action, data such as documents and e-mail messages related to the case usually need to be reviewed, and an effort to preserve this information must be made. Exchange 2010 allows you to protect and maintain this data by placing mailboxes on litigation hold. This prevents users or retention policies from modifying or removing any messages that may be required during the legal discovery process. In this recipe, you'll learn how to manage litigation hold settings for mailboxes from the Exchange Management Shell.
To place a mailbox on litigation hold, use the
Set-Mailboxcmdlet :Set-Mailbox -Identity dsmith -LitigationHoldEnabled $true
To remove the retention hold setting from the mailbox, use the same command, but set the
-LitigationHoldparameter to$false:Set-Mailbox -Identity dsmith -LitigationHoldEnabled $false
