The AllowMigration switch allows a quarantined mailbox to be moved to another mailbox database or to the cloud. Moving a mailbox is one method of correcting data corruption that's required before releasing the mailbox from quarantine. You don't have to specify a value with the AllowMigration switch.




The Confirm switch can be used to suppress the confirmation prompt that appears by default when this cmdlet is run. To suppress the confirmation prompt, use the syntax -Confirm:$False. You must include a colon ( : ) in the syntax.




The Duration parameter specifies how long the mailbox should remain quarantined. The default duration is 24 hours.

To specify a value, enter it as a time span: dd.hh:mm:ss where d = days, h = hours, m = minutes, and s = seconds.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
