Email TeamMate requested permissions

TeamMate uses Azure Active Directory v1.0 endpoint's permissions and consent.

The requested permissions and why they are required are listed in the Microsoft 365 App Compliance Program.

Security notes:

  • Email TeamMate only asks for delegated permissions, and not for application permissions. The effective permissions are the least privileged intersection of the delegated permissions Email TeamMate has been granted (through consent) and the privileges of the currently signed-in user. Email TeamMate cannot have more privileges than the signed-in user. As a result, TeamMate users can never access content they are not authorized to view. For more information, read Permissions and consent in the Azure Active Directory v1.0 endpoint.
  • The only permission Email TeamMate stores is User.Read. We save the user name of signed-in users for identifying them through various platforms.

To verify that Email TeamMate consent is properly configured:
