Delete Public folders from inSync

As an administrator, you can delete Public folder configured for backup anytime from inSync.

  • When you delete Public folder, inSync permanently deletes all the data backed up for those Public folder.
  • You can delete Public folder for which the backup is in progress.
  • You cannot delete a Public folder if it is enabled with Data Lock.

  2. Select the Public folder name that you want to delete.
  3. Click Delete
  4. On the confirmation window, specify the reason for deletion (the reason is mandatory with a character limit between 10-150). The reason for deletion will be captured in the Admin Audit trail for auditing purposes.

  5. Click Delete.  All the data backed up for the Public folder will be deleted temporarily. You can rollback the deleted Public folder within a configurable rollback window. After the rollback window expires, the Public folder will be deleted permanently. See Rollback Actions for details.

 To use Rollback Actions, you need the Security Essentials license. Contact Support to obtain the license. Currently, this feature is available only for the Public Cloud customers.


Rollback Considerations: You cannot rollback Public folder if you delete it, add the same Public folder (through auto-discovery or another method) while the deleted Public folder resides in Rollback Actions, and try to rollback the Public folder .

Public folder mailbox autosplit

As content grows over time for your Public folder data, Microsoft 365 handles the management of your Public folder mailboxes wherein:

  • The mailboxes are automatically split as the mailbox quota usage exceeds the threshold limit.
  • The autosplit ensures the mailboxes can accept the growing Public folder content over time.

For more information, see the Microsoft blog post for the Public folder mailbox autosplit scenario.

If mailboxes are split for any of your existing Public folders, the Public folder workload selection page will display a duplicate folder in the disabled state with -old suffix in the name of the Public folder.


Note: You must delete duplicate folders to manage your Public folders efficiently.
