Microsoft Teams

To back up Microsoft Teams data, Veeam Backup for Microsoft 365 requires access to the Exchange mailbox of the group associated with a team and to the SharePoint site of this group. Thus, the Veeam Backup account that you use to add an organization using modern authentication with legacy protocols allowed or basic authentication 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 Veeam Backup account that you use to add an organization must meet the following requirements:

  • The account must have a Microsoft 365 license that permits access to Microsoft Teams APIs. The minimum sufficient license is Microsoft Teams Exploratory experience. For more information about the Microsoft Teams Exploratory experience, see this Microsoft article.
  • The account must have the Team Administrator role assigned.


Consider the following:

  • In case you add an organization in Veeam Backup for Microsoft 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.
  • When backing up Microsoft Teams data in an organization added using the basic authentication, Veeam Backup for Microsoft 365 at first adds a service account to every team and then removes it.
  • For more information about permissions required to restore Microsoft Teams data from backups created by Veeam Backup for Microsoft 365, see Permissions for Veeam Explorer for Microsoft Teams.
