Microsoft 365 protection has the following limitations depending on the service:
Teams
- Only user accounts with Security Officer permissions can restore from deleted or unlicensed accounts
- Only user accounts with Security Officer permissions can delete backup history for accounts
See the User roles for full details on how this might affect you.
- All private channels will be restored as public
- Deleted channels will not be backed up
- Guest users in the channels will not be restored in the channels
Guest users must be added after the channel is restored.
- It is not possible to configure settings for the General channel and as such will restore Microsoft's default settings
- Group settings cannot be restored, Microsoft's default group settings will be applied on restored channels
- If a Team is Archived prior to the recovery, it will restore in full and must be archived again manually
- Tags and Apps in the Team will not be backed up
- We do not currently support backup or restore of Microsoft Document Sensitivity Labelling. See Learn more about sensitivity labels
Exchange

- Only user accounts with Security Officer permissions can restore from deleted or unlicensed mailboxes
- Only user accounts with Security Officer permissions can delete backup history for accounts

- We do not support hybrid Microsoft 365 installations for backup. On-premises mailboxes may be detected as connected to Microsoft 365 but we are unable to protect them as access is not given to the on-premises installation
- We do not currently support backup or restore of Public folders. This is due to the configuration of Microsoft data layers
- We do not currently support backup or restore of Tasks
- Colour categories will not be included in the backup and restore of Contacts
- Protection for Archived mailboxes or a native Archive folder is not provided through backup
- You cannot backup from unlicensed mailboxes. Please confirm that the mailbox does not fall under one of these scenarios:
- The mailbox is present, but the license was removed. In this case, it will not be possible to add the mailbox to the backup
- The mailbox and license were removed while the backup is in progress. In this case, the backup will not be able to complete and you will see the error "Unable to backup user without license" for such mailboxes
- The mailbox is removed before the backup is started. In this case, the backup will run but skip this mailbox
To resolve this issue you will need to undelete the mailbox via the Microsoft 365 Admin portal and provide a license to the mailbox. After the backup is completed for the mailbox, you can then delete the mailbox and remove the license. We cannot backup deleted mailboxes, even if they have a license assigned.
