Microsoft has designed the Exchange Server as a robust application that creates a sizeable database with multiple GBs, and each consisting of multiple mailboxes. Users are granted the authority to delete older or unwanted mailboxes to create space for new data. However, this authorization also increases the chance of unintentional or sudden mailbox deletions. To overcome such threats, Microsoft offers several tools that help administrators monitor for unusual activity within Exchange. These tools include:
While these features reduce the risk of accidental data deletion from Exchange Server, there remains a possibility of users deleting mailboxes accidentally.
In Exchange Server 2016, the deleted mailboxes can be recovered either manually or using third-party solutions. The process involves creating a user account and connecting it to the disconnected mailbox. However, this is possible only if the mailbox’s retention period has not expired.
In Exchange Server 2016, when you delete a mailbox, it does not get deleted permanently; instead, it is retained for a default period between 14-30 days. Within this retention period, users can restore the deleted mailbox. However, after this 30-day period, the mailbox will be removed permanently from the database.
Try Kernel for Exchange Server recovery software to recover deleted mailboxes from Exchange 2010/2013/2016/2019 within their retention period.
To configure the mailbox retention period manually, you can use the Exchange Admin Center (EAC).
To restore a deleted mailbox, connect it to a user account. The process is similar for shared, linked, and resource mailboxes. This can be done using the Exchange Admin Center (EAC) or Exchange Management Shell (EMS). Alternatively, you can use third-party tools to recover data from deleted mailboxes.
You can connect deleted mailboxes to user accounts using the Exchange Admin Center. The process is same for all: linked, resource, and shared mailboxes.
Now, your Exchange will connect the deleted mailbox to the selected user account, 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 (shared, linked, room, or equipment mailbox). The general syntax is:
Before starting, remember that not more than one user can connect to an Exchange mailbox (as GUIDs must be unique). To reconnect a deleted mailbox:
While the solutions discussed above are useful for mailbox recovery, there are scenarios where you need to recover deleted mailboxes to formats such as Outlook PST, Exchange Server, Microsoft 365, etc.
In such cases, an automated tool named Exchange Recovery offer a simple, reliable, and effective way to recover and save deleted mailboxes from Exchange 2016 or any other Exchange Server database files. The tool employs smart algorithms to ensure a smooth and quick data recovery.
Now, let’s examine the whole process of recovering deleted mailboxes of Exchange 2016 with minimum effort.
Thus, the software repair corrupt Exchange database data along with deleted mailboxes and items. You can also export EDB to PST or other destinations like Microsoft 365. You can try this efficient solution to recover deleted mailboxes without disturbing data integrity.
It’s important to note that manual recovery is only possible within the retention period. You can restore deleted mailboxes in Exchange Server 2016 through EAC or EMS PowerShell commands. But, once the mailbox is deleted permanently, you can’t recover it through a manual process. In that case, only professional software like Kernel for Exchange Server can retrieve a permanently deleted mailbox from a database. It will scan the database and present the mailbox with complete data integrity.
