Remove Disconnected/Soft Deleted Mailboxes from Exchange 2010/2013 Database

When moving mailboxes between Exchange databases the move complete with a warning. This is because Exchange server sometimes does not fully delete the mailboxes from the source database immediately upon completion of the move the source mailbox database is switched to a “soft-deleted” state. To resolve this you need to remove the disconnected or soft deleted mailboxes from the old database to free up space.

The difference between Disabled Mailboxes & Soft-Deleted Mailboxes

Disabled Mailboxes: When you delete a mailbox using the Remove-Mailbox or Disable-Mailbox cmdlet, those consider as disabled mailbox and Exchange retains those mailboxes till retention period.

Soft-Deleted Mailboxes: When we move mailbox from one database to another, the source mailbox does not get permanently deleted and mailbox switched into the soft-deleted mode.

Get-MailboxStatistics –Database “MailboxDatabase″ | Where-Object {$_.DisconnectReason –eq “Disabled”}

$Mailboxes = Get-MailboxStatistics -Database “MailboxDatabase″ | where {$_.DisconnectReason -eq “Disabled”}
