Microsoft has updated the Microsoft-managed default app consent policy in Entra ID to align with the Secure Future Initiative and the Secure by Default principle. This update strengthens admin control over third-party app access to Exchange and Teams content.
Important:
This update only affects tenants using the Microsoft-managed user consent policy. Organizations using a custom or admin-defined policy are not affected.
Timeline
The rollout should be completed by late November 2025.
How does this affect your organisation?
In mid-August, Microsoft enabled the new Microsoft-managed app consent policy for organisations using the default Entra ID configuration.
The first four blocked permissions were:
- Microsoft Graph – Files.Read.All
- Microsoft Graph – Files.ReadWrite.All
- Microsoft Graph – Sites.Read.All
- Microsoft Graph – Sites.ReadWrite.All
In October, Microsoft informed that these four permissions would be extended to include additional permissions for apps accessing Exchange and Teams content. These new permissions are now rolling out and include 20 additional excluded permissions for Outlook Mailbox, Outlook Mail, Outlook Calendar, Teams Chat, and Teams Meetings.
- Organisations using custom user consent policies are not affected. Read my July post for step-by-step guidance on creating a custom app consent policy.
- Users who have already granted consent to an app can continue using it without interruption.
- New users or apps requesting new or broader permissions are blocked. Microsoft recommends configuring an admin consent workflow to manage these requests.
For example, Doodle uses the Calendars.ReadWrite permission, which is now one of the newly excluded permissions.
New users can no longer add the app.
I exported all excluded permissions from the Microsoft-managed app consent policy.
The following table lists the 24 permissions currently excluded by the Microsoft-managed app consent policy. The resource ID of Microsoft Graph is 00000003-0000-0000-c000-000000000000.
