How to connect a deleted mailbox to a user account?

To restore a deleted mailbox, you need to connect it to a user account. The process is similar for shared mailboxes, linked mailboxes, and resource mailboxes. And this can be done using the Exchange admin center (EAC) or Exchange Management Shell (EMS). Alternately, you can use third-party tools to recover data from deleted mailboxes.

1st Solution – Connect a Deleted Mailbox to a User Account Using EAC

You can connect deleted mailboxes to user accounts using Exchange Admin Center. The process is same for all all types or mailboxes – linked mailboxes, resource mailboxes and shared mailboxes.

Open EAC and go to Recipients>Mailboxes. Click More and then select Connect a Mailbox option. Choose a deleted mailbox from the list of disconnected mailboxes. Click Connect; click Yes. Now, you will receive a list of user accounts (not mail-enabled). Click the user account to which you want to connect the selected deleted mailbox. After that, click OK.

Now, your Exchange will connect the deleted mailbox to the selected user account, and so the mailbox is available to the user again.

2nd Solution – Connect a Deleted Mailbox to a User Account Using EMS

When you use Exchange Management Shell to connect a deleted mailbox to a user account, you need to specify the type of mailbox (whether it is shared, linked, room, or equipment mailbox). The general syntax is:

Connect-Mailbox -Identity “mailbox name” -Database -User “AD user account name” -Alias


3rd Solution – Reconnect a Deleted Mailbox

Before starting, keep in mind that not more than one user can be connected to an Exchange mailbox (as GUIDs must be unique). To reconnect a deleted mailbox, start Exchange Server Manager. Go to the mailbox store having disconnected mailboxes. Under the mailbox store, click Mailboxes. Then, click Clean up Agent from the right-click menu. Select the disconnected mailboxes for recovery and click Reconnect. Finally, select the related user account and then click OK.
