To back up Microsoft Teams data, Veeam Backup for Microsoft Office 365 requires access to the Exchange mailbox of the group associated with a team and to the SharePoint site of this group. Thus, the account that you use to add an organization must have permissions required for backup of Exchange Online and SharePoint Online data. For more information, see Microsoft Exchange Organizations and Microsoft SharePoint and OneDrive for Business.
In addition, the account that you use to add an organization must meet the following requirements:
- The account must have a Microsoft Office 365 license that permits access to Microsoft Teams API. The minimum sufficient license is Microsoft Teams Exploratory experience.
- The account must have the Team Service Administrator role assigned.
In case you add an organization in Veeam Backup for Microsoft Office 365 using the modern authentication method with legacy protocols allowed, and specify different accounts to connect to Microsoft Exchange and Microsoft SharePoint, the required license and role must be assigned to the account used to connect to Microsoft SharePoint.
