Restore

This section will explain how you can restore entire mailboxes or individual mailbox folders from a backup and export mailbox backups to PST.

To restore a mailbox from a backup or to export particular items from a backup to PST:

1. Log in to M365 Manager Plus and click the Auditing & Monitoring tab.
2. Navigate to Backup > Exchange Online > Restore.
3. Select the tenant with the mailbox for which data is to be restored or exported from the Microsoft 365 Tenant drop-down menu.
4. In the Select Backup drop-down menu, select the schedule which contains the mailbox to be restored.
5. Once you have selected the schedule, a list of all mailboxes that are backed up in the selected schedule will be displayed. The result will also contain information like the recipient type, email address, total size of the backup, and number of items backed up during the last backup cycle. Click the view history icon to see complete information about every backup operation carried out for that particular mailbox.
6. Select the mailboxes that you want to restore or export to PST and click the Review and Restore button. You can also use the search icon to shortlist the mailboxes using the name or the email address of the user.
7. On the screen that appears, the left-pane provides the list of all the selected mailboxes.
8. Use the Select All link to restore or export all the selected mailboxes.
9. To restore or export particular mailboxes to the backed up version, mark the check box against the mailbox's name. You can also use the search bar at the top of the left pane to search for a particular mailbox.
10. To restore individual items like contacts, notes, or individual mailbox folders, click the mailbox name to display all folders and select the items that you wish to restore.

Note: Once you've selected a mailbox folder, you can further limit your search to items that match specific criteria by clicking the search icon at the top-left corner of the result screen. Depending on the folder that you've selected, you'll be provided with a list of filters.

11. Once you have selected the mailboxes, you can:
    • Restore the mailbox items to the backed up state.
    • Export the selected mailbox items to PST format.

Restore the mailbox items to the backed up state

To restore the selected items, click the Restore button located at the bottom of the page. The Restore Wizard pop-up will appear.

1. The first screen shows the mailboxes that you selected for restoration and the number of items that will be restored for each mailbox. Click Next after verifying the selection.
2. Choose whether the contents should be restored to the same location or a different location.
   • If you wish to restore the contents to the same location, select Restore to Original Location.
   • If you wish to restore the contents to a different location, select Restore to Different Location and click Browse. You can restore the contents of the mailbox to an on-premises Exchange mailbox or Exchange Online mailbox. Click Select Target Folder to provide the folder in which the items are to be restored.
3. Provide a name for the restore operation. You can choose to restore just the modified items or missing items by selecting the appropriate option. Click Restore to begin the restoration process.
4. Click Operation History at the bottom-right corner of the screen to view the status of the last five restorations. Clicking Stop will stop the restore operation. Clicking the View All link in the pop-up will take you to the Operation History screen. For more information on what the restore history section provides, see this help document.

Export the selected mailbox items to PST format

To export the selected mailboxes or mailbox items as a PST file, click the Export button located at the bottom of the page.

1. In the pop-up that appears, provide a name for the export job.
2. Select the repository in which the exported PST must be stored.
3. Click Advanced Settings to configure the following additional settings:
   • To split the PST file into multiple smaller files to overcome the import limit of Outlook, select Enable Split PST and provide the maximum size for each file. The application supports splitting PST files to a maximum of 50GB.

     Note: The individual PST files might slightly exceed or fall short by a maximum of 10% of the specified file size.

   • To add a layer of security for your PST, select Secure PST with a Password and provide a password.
4. Click Export to begin the process.
