Removing a Mailbox from Quarantine in Exchange Server 2013

Share this:

In this Tutorial we are going over the process to find out which mailboxes are being quarantined and remove them from that state using a new cmdlet introduced in Exchange Server 2013. The same procedure is also valid for Exchange Server 2016 (Preview).


In Exchange Server 2010 the process required more manual work (you can check the step by step ), however a new set of cmdlets *-MailboxQuarantine were introduced and they help the administrator to add and remove mailboxes in the quarantine.

A good way to check a list of all mailboxes that are being quarantined is using the following cmdlet:

Get-Mailbox –Server <Server-Name> –ResultSize unlimited | Get-MailboxStatistics | Where-Object { $_.IsQuarantined –eq $True } | Select DisplayName,IsQuarantined,QuarantineEnd


In order to remove a mailbox from there, just use the following the cmdlet:

Disable-MailboxQuarantine <mailbox>


As you can see, the process is much easier when compared with previous version of the product.
