Summary: If you have accidentally deleted a mailbox in the Exchange Server 2010 database, follow this detailed guide to learn some best methods to restore and recover the deleted mailboxes or emails.

What Happens When Exchange Server Mailbox is Deleted?

When a user account connected to a mailbox is deleted from Exchange’s Active Directory (AD) or if a mailbox is deleted by using Exchange Management Console or Exchange Admin Center (EAC), the deleted mailbox is retained as a disconnected or disabled mailbox. The mailbox remains on the Exchange server in a disabled state for a certain time-period, defined in the mailbox retention settings.

Users can reconnect the mailbox to the original or another user account any time before the retention period ends to restore and recover the deleted/disconnected mailbox in Exchange 2010. After the mailbox is connected, the user can log in to Outlook account to access the mailbox items such as emails, contacts, notes, calendars, etc.

Points to Remember

  1. The mailbox that has been deleted may or may not appear as a ‘disconnected mailbox’ immediately after deletion. It can take about 15 minutes to an hour before the mailbox is marked as disconnected.
  2. If the mailbox still does not appear, it is altogether a different issue and users need to look for a solution.
  3. It is possible to connect a disconnected mailbox to a new user account in AD or existing user account with an associated mailbox.

Methods to Recover Deleted/Disconnect Mailbox in Exchange 2010

The disconnected Exchange 2010 mailbox can be connected and recovered in different ways, such as by using Exchange Management Console (EMC), Exchange Management Shell (EMS), and via third-party Exchange recovery software, such as Stellar Repair for Exchange. The software can recover both deleted mailboxes and mailbox items from the Exchange database in a few clicks.
