Decisions Microsoft Graph permissions explained

During approval of the Decisions Azure AD enterprise application, you are presented with a set of Microsoft Graph permissions. This article explains what permissions Decisions requests and what they are used for.

Decisions is built on top of Office 365 and integrate tightly with Office 365 groups and the users calendars to provide features related to preparing, running and following up on structured meetings. All communication between end user devices and your Office 365 tenant goes directly, and not routed through Decisions server side services. Please see architecture and security overview for more details.

Delegated Permissions

The Microsoft Graph exposes two categories of permissions; Application permissions and Delegated Permissions. Application permissions allow an app to act as any user, while delegated permission only allow for signed in users of the application.

All permissions requested by Decisions are Delegated Permissions. Decisions runs as a single page application (SPA) in a browser sandbox on the end user device. The permissions for the user of the app is limited by both Decisions Microsoft Graph permissions and the end-user’s Office 365 permissions.

By using Delegated Permissions, users of Decisions will never get access to any resources they not already have access to in your organizations Office 365 tenant. For example; if a user does not have access to a Office 365 group in your tenant, they user will not get access to that through Decisions either - because Decisions only use delegated permissions.

Please refer to the Microsoft Graph permissions documentation for more details on delegated permissions.
