Microsoft Exchange Server has many security features that help the administrator to keep the mailboxes safe in the databases. Some of the available tools are-
All these features minimize the chances for accidental data deletion from Exchange Server. But the user can still delete the mailbox accidentally
Talking about the Exchange Server 2016, deleted mailboxes can be recovered manually or using third-party solutions. For recovery, you can create a user object and connect the user account to the disconnected mailbox. However, this is possible only if the retention period of the mailbox is not over.
Try Kernel for Exchange Server recovery software to recover deleted mailboxes from Exchange 2010/2013/2016/2019 within their retention period.
When you delete an Exchange mailbox, it does not get deleted permanently; instead, it is retained for 30 days by default (unless manually purged). Within the retention period, it is possible for users to restore the deleted mailbox. But once this 30-day period is over, the mailbox will be removed permanently from the database.
To configure the mailbox retention period manually, you can use the Exchange Admin Center (EAC). Select servers on the left pane. Under the databases tab, select the required database and then click the edit icon. In Limits option, modify the number of days in the Keep deleted mailboxes for (days) field (by default the number is 30).
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.
You can connect deleted mailboxes to user accounts using Exchange Admin Center. The process is same for all types of mailboxes – linked mailboxes, resource mailboxes and shared mailboxes.
Now, your Exchange will connect the deleted mailbox to the selected user account, and so the deleted mailbox is available to the user again.
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:
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.
All the solutions mentioned above can be used for the recovery of deleted mailboxes. But there are situations in which you need to recover deleted mailboxes to Outlook PST, Exchange Server, Microsoft 365, etc.
In that case, third-party tools like Kernel for Exchange Server Recovery can be used.
