Considerations and Limitations

This section lists considerations and known limitations of Restore Portal.

• Restore Portal is supported only for organizations added to Veeam Backup for Microsoft 365 using the modern app-only authentication method. Azure AD application that you have used to add your Microsoft 365 organization must have permissions for data restore using an application certificate.

• Backups created for on-premises Microsoft organizations cannot be restored using Restore Portal. For hybrid organizations, Restore Portal allows you to restore only data from backups created for Microsoft 365 organizations.
• Microsoft Teams data is not supported for explore and restore using Restore Portal. If a restore operator is allowed to manage the entire Microsoft 365 organization, only Microsoft Exchange, Microsoft SharePoint and Microsoft OneDrive for Business data will be available for explore and restore.
• Group mailboxes data is not supported for explore and restore using Restore Portal.
• Restore Portal allows you to restore data from the latest restore point that available in a backup repository.
• Items of different types that you added to the restore list (for example, mailbox items, OneDrive and SharePoint files) will not be restored simultaneously. You must configure and run different restore operations for Exchange, SharePoint and OneDrive items.
• Backups that were retrieved from backup copies cannot be restored using Restore Portal.
• If you want to restore your backed-up data using Restore Portal in different regions, you must use a separate installation of the Veeam Backup for Microsoft 365 REST API component and a separate Azure AD application in each Microsoft Azure region.
