Exchange 2010 – How to Recover Deleted Mailboxes

When a mail-enabled user account is deleted from Active Directory or a mailbox is deleted using the Exchange Management Console, the mailbox is retained as a disconnected mailbox according to the mailbox retention setting. You can reconnect the mailbox to the original user account or another user account if necessary.

Note:

  • Deleted mailboxes may not appear as a ‘disconnected mailbox’ immidiately . It can take 15 minutes to an hour before the mailbox is listed. If it still doesn’t appear, see: Exchange 2010 – Disconnected Mailbox not appearing
  • You can connect a disconnected mailbox to a user account only if the account doesn’t already have a mailbox associated with it.

  1. Deleted emails can be restored from deleted items folder (using Outlook or OWA) in case when the retention period is not over but I have noticed on many forum sites, IT communities that they are not able to restore deleted emails from deleted items folder as well. So, in such cases professional tools like Stellar Exchange Recovery Software, Unistal Edb recovery etc could be handy as these tools have powerful scanning algorithms that can easily restore all accidentally deleted mails from edb file
