In this comprehensive guide, we'll walk you through the process of recovering a user mailbox in Exchange 2019, explore the different recovery options available, and provide insights into best practices to ensure seamless mailbox management.
Why do User Mailboxes Need to Be Recovered?
User mailboxes can be lost or deleted in Exchange 2019 for various reasons, including:
- Accidental deletion by users or administrators
- Database corruption or system failures
- Mailbox migration issues during upgrades or transitions
- Retention policy errors, causing automatic deletion
- Exceeding mailbox storage limits, leading to data loss
Prerequisites for Mailbox Recovery in Exchange 2019!
Before initiating the recovery process, ensure you meet the following prerequisites:
- Administrator Access: You need to be a member of the Organization Management role group to perform mailbox recovery tasks.
- Proper Backup: Regular backups (full and incremental) are essential to ensure recovery is possible after a significant data loss.
- Retention Period: Exchange 2019 retains soft-deleted mailboxes for a default period of 30 days. Hard-deleted mailboxes can be recovered from backups or a database restore.
There are two primary methods for recovering deleted mailboxes in Exchange 2019:
- Soft Deleted Mailboxes: These mailboxes are deleted by the user but can still be recovered within the retention period.
- Hard Deleted Mailboxes: These mailboxes are permanently deleted, either by the user or due to corruption, and may require database recovery or restoration from backup.
Soft Deleted Mailboxes
Soft-deleted mailboxes are retained for 30 days by default. They are recoverable without requiring a full restore, provided you act within the retention period.Hard Deleted Mailboxes
Hard-deleted mailboxes are permanently removed, bypassing the retention period. Recovering these mailboxes often involves restoring them from backups or using the New-MailboxRestoreRequest cmdlet if a mailbox database is still intact.How to Recover a Soft Deleted Mailbox?
Soft-deleted mailboxes in Exchange 2019 can be recovered using the Exchange Admin Center (EAC) or the Exchange Management Shell.
Recovering via Exchange Admin Center (EAC)
- Log into the Exchange Admin Center: Open a web browser and log in to the Exchange Admin Center using your admin credentials.
- Navigate to Recipients: In the EAC, go to the Recipients section and select Mailboxes.
- Find the Deleted Mailbox: Under the More Options section, click on Deleted Mailboxes. This will show all mailboxes that have been soft-deleted but are still recoverable.
- Select and Recover the Mailbox: Locate the mailbox you want to recover, select it, and click on Restore. You will be prompted to confirm the recovery process.
- Completion: After a few moments, the mailbox will be restored and will be available for the user to access again.

How to Recover a Hard Deleted Mailbox?
When a mailbox is hard deleted, it's no longer accessible through the regular recovery methods. Here’s what you can do:- Database Restore: If the mailbox was permanently deleted and is beyond the retention period, restoring from a backup is necessary. A full restore will bring back the entire database, including all mailboxes and their contents.
- New-MailboxRestoreRequest Cmdlet: You can use the New-MailboxRestoreRequest cmdlet to recover a mailbox from a backup or another database copy. You must ensure that the mailbox database has been properly backed up and is available for recovery.
Restoring Mailboxes from Backups
If you need to recover a hard-deleted mailbox or multiple mailboxes, the easiest method is to restore from a backup. Exchange 2019 supports integration with various third-party backup solutions, such as Veeam, Veritas, and more.- Verify the Backup: Check that the backup includes the mailbox database that contains the deleted mailboxes.
- Perform the Restore: Follow the steps outlined in your backup solution’s guide to restore the mailbox database.
- Use the New-MailboxRestoreRequest Cmdlet: After restoring the database, use the New-MailboxRestoreRequest cmdlet to restore individual mailboxes if necessary.
Recovering Mailboxes Using the New-MailboxRestoreRequest Cmdlet
The New-MailboxRestoreRequest cmdlet is a powerful tool for recovering deleted mailboxes, especially when the mailboxes are hard deleted or require recovery from an alternate database. Here’s how to use it:Run the following command to restore the mailbox:
New-MailboxRestoreRequest -SourceMailbox <source database> -TargetMailbox <target mailbox>
- Monitor the Restore Process: Use the Get-MailboxRestoreRequest cmdlet to monitor the status of the restore operation.
- Complete the Recovery: Once the restore is complete, verify that all mailbox data has been recovered and that the user can access their emails.
How to Prevent Mailbox Deletion in the Future?
Preventing accidental mailbox deletion is key to maintaining business continuity. Here are some strategies to help:- Configure Retention Policies: Set appropriate mailbox retention policies to preserve data for a longer period.
- Implement Litigation Hold: Use Litigation Hold to preserve mailbox data for legal or compliance reasons.
- User Training: Ensure that users are aware of the consequences of deleting mailboxes and emails.
