Problem

In older versions of Exchange, we just had to “Purge” disconnected mailboxes, now we don’t have that option.

Solution

WARNING this will remove ALL disconnected mailboxes, make sure you actually want to do this before proceeding.

Launch > Exchange Management Shell.

Issue the following commands;

[box] $mailboxes = Get-ExchangeServer | Where-Object {$_.IsMailboxServer –eq $true} | ForEach-Object { Get-MailboxStatistics –Server $_.Name | Where-Object {$_.DisconnectDate –notlike ‘’}} | select displayname, mailboxguid, database [/box]

Then;

[box] $mailboxes | ForEach { Remove-Mailbox -Database $_.Database -StoreMailboxIdentity $_.MailboxGuid -confirm:$false } [/box]

2. If you have the Exchange Management console open (as above), you may need to refresh, before they disappear.
