Recovering Deleted mailbox from Exchange Server

Most Exchange admins have had to face the scenario where a mailbox have been accidentally or unintentionally deleted. One of the good things about Exchange Server is that when a mailbox gets deleted, it is usually not permanently deleted. Instead, what happens is that the mailbox is put in a disabled state but is still present in the mailbox database. This is a blessing as the mailbox will remain in the database till the retention policy period expires, which means you can reconnect and access it.

The default retention period is 30 days. Once deleted, the mailbox is flagged for deletion or purging at the end of retention period, while still kept intact in the information store. You may however choose to purge or permanently delete the mailbox at any time even before the retention policy ends. Follow the steps below to configure your retention policy

  1. Right click on the Mailbox store and select properties.
  2. Go to the Limits tab.
  3. Change the ‘Keep deleted mailboxes for’ value to your liking (the value is in days).

Steps to reconnect deleted mailboxes

As long as the mailbox has not been permanently deleted, you can always connect it to an Active Directory user account using the Exchange Admin Center. Here are the steps that can be used to reconnect disabled mailboxes:

  1. Goto Exchange Admin Center (EAC) and then Recipients > Mailboxes.
  2. Select More and click Connect to mailbox. All the disconnected mailboxes in the organization will be listed.
  3. Choose the disconnected mailbox that you wish to reconnect. (In case the mailbox is not marked as disconnected you should right click it and select ‘Cleanup Agent’).
  4. Click Yes when the confirmation dialogue pops up.
  5. Exchange will now reconnect the mailbox to corresponding user account.

For connecting to a new user, first goto ‘Active Directory Users and Computers’ and create a new user with Exchange mailbox. Once done, you can follow the above steps to connect mailbox to the new user.

What if you are not able to reconnect the mailboxes as mentioned above? Is there any other way?
