The dedicated Office 365 service account used for Keepit backup must be assigned the Global administrator role. This is necessary because only through a user with this role can Keepit obtain full access to data. If this is not done, Keepit will not be able to include all data in the backup.
The Global administrator must also be assigned an Office 365 license that gives this user access to Microsoft Teams. This license will allow the Keepit software to make the user a member of all Office 365 Teams and Groups. This is vital because Keepit can only back up Groups that the Global administrator is a part of.
The following license plans give the Global administrator access to Microsoft Teams: Business Essentials; Business Premium; Enterprise E1, E3, or E5; Enterprise E4 (for anyone who purchased this plan prior to its retirement).
