Group.Read.All

Allows the app to list groups, and to read their properties and all group memberships on behalf of the signed-in user. Also allows the app to read calendar, conversations, files, and other group content for all groups the signed-in user can access.

For Microsoft 365 groups, Group.* permissions grant the app access to the contents of the group; for example, conversations, files, notes, and so on.

In some cases, an app might need extra permissions to read some group properties like member and memberOf. For example, if a group has one or more service principals as members, the app also needs permissions to read service principals, otherwise Microsoft Graph returns an error or limited information. To read the full information, the app also needs permissions in the organization to read service principals. For more information, see Limited information returned for inaccessible member objects.

Group.* permissions are used to control access to Microsoft Teams resources and APIs. Personal Microsoft accounts are not supported.

Group.* permissions are also used to control access to Microsoft Planner resources and APIs. Only delegated permissions are supported for Microsoft Planner APIs; application permissions are not supported. Personal Microsoft accounts are not supported.

Merill's Note

For an app to access data in Microsoft Graph, the user or administrator must grant it the permissions it needs. This article lists all the Microsoft Graph APIs and your tenant data that can be accessed by the application (vendor/developer) if you consent to the Group.Read.All permission.

If you need to create an audit report of the permissions granted to all the apps in your tenant, you can run the Export-MsIdAppConsentGrantReport command. See How To: Run a quick OAuth app audit of your tenant
