Recovering an Exchange mailbox that is deleted accidentally can be one of the most frustrating things for a user as with the deletion of the user mailbox, its associated user account also gets deleted. But, the relieving part is that a mailbox is never removed permanently from Exchange 2010. When you accidentally delete a mailbox in Exchange 2010, it gets disconnected from your account and held in the directory for 30 days which is the default mailbox retention period. You can reconnect any deleted mailbox during this period.
However, when the retention period ends, the mailbox will be deleted permanently. So, if you want to reconnect a mailbox, then you should verify the deleted mailbox retention policy. Follow the below steps to verify the retention policy:
- Go to Exchange 2010 Management Console and expand Microsoft Exchange On-premises in the navigation pane.
- Expand Organization Configuration and select the mailbox for which you want to verify the retention policy.
- Select the Database Management tab in the Mailbox pane.
- Click on the respective Mailbox Database that you want to verify.
- Choose properties and click the Limits Tab.
- Verify the detention policy or settings and adjust the days according to your requirements.
After verifying the retention policy, you’ll get to know whether the deleted mailbox you want to connect to is still available or not.

Checking Disconnected Mailboxes
Also, you’ll have to check the Disconnected Mailbox list, as Exchange 2010 disconnects deleted emails.
Note: After the deletion of any Exchange mailbox, it would take about 15 minutes to 1 hour to get it listed in the disconnected mailbox list from the time of deletion.
Here’s how you can access disconnected mailboxes.
- Go to Exchange Management Console and expand Microsoft Exchange On-premises
- Now, expand Recipient Configuration and Select Disconnected Mailboxes.
- Here you can find the deleted mailbox
However, if you don’t find a recently deleted mailbox in disconnected mailboxes, then don’t panic. Deleted mailboxes don’t appear in the folder until Exchange 2010 cleans its database.
Force Cleaning Exchange Mailbox Database
The process of cleaning the database takes some time, but you can also force Exchange 2010 to clean databases. Follow the below steps to force Exchange 2010 to clean the database.
- Go to Start and type Exchange Management Shell
- Now, right-click Exchange Management Shell and click Run as administrator
- A prompt will appear on the screen, enter the following command to it:
- If the next command line returns, the cleaning database has been completed successfully.
After cleaning the Exchange 2010 mailbox database, you can recover the deleted mailboxes. Here how:
Recovering Deleted Mailboxes in Exchange 2010 (Within Retention Period)
- Go to Exchange System Manager and locate the mailbox store that contains disconnected mailboxes
- Under the mailbox store, select the Mailboxes object
- Now, right-click on the disconnected mailbox, and then select Reconnect
- Select the mailbox type and click Next.
- Select the appropriate user using the Browse option under the Existing user section from the opened wizard and click Next.
Note: Disconnected mailboxes already associated with another mailbox cannot be reconnected to a user account.
Using this technique, only one user can connect to a mailbox because to be unique across an entire forest, all globally unique identifiers are required.
Reconnecting Deleted Mailboxes to a New User Object
You can also reconnect a deleted mailbox to a new user object using Active Directory.
- Go to Active Directory Users and create a new user object.
- While creating a new user object, click to clear the Create an Exchange Mailbox checkbox.
- The user account will be connected to an already existing mailbox.
- Now, follow the same steps of Recovering Deleted Mailboxes in Exchange 2010 as mentioned in the previous section.
