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;
$mailboxes = Get-ExchangeServer | Where-Object {$_.IsMailboxServer –eq $true} | ForEach-Object { Get-MailboxStatistics –Server $_.Name | Where-Object {$_.DisconnectDate –notlike ‘’}} | select displayname, mailboxguid, database
Then;
$mailboxes | ForEach { Remove-Mailbox -Database $_.Database -StoreMailboxIdentity $_.MailboxGuid -confirm:$false }
2. If you have the Exchange Management console open (as above), you may need to refresh, before they disappear.
