Can you check what are the permissions in access token at https://jwt.ms? Also try to check logging into the [graph explorer](https://aka.ms/ge) — Shiva Keshav Varma, Apr 20 '22 at 12:59
The permissions are : "scp": "Mail.Read User.Read User.Read.All profile openid email", It's weird because in Azur I also have Tasks.ReadWrite permissions — Christopher Lessirard, Apr 20 '22 at 13:25
Try adding Tasks.ReadWrite permission and test it. Check if you added Delegated permission or application permission. — Shiva Keshav Varma, Apr 20 '22 at 13:28
I add a screen of my app permissions in Azure ans there is the Tasks.ReadWrite but this permission isn't in the token — Christopher Lessirard, Apr 20 '22 at 13:36
Are you using MSA account or Work account? Try getting the token once again and see if it works. — Shiva Keshav Varma, Apr 20 '22 at 13:40
I think this is a work account I use it with the student offer. I will retry — Christopher Lessirard, Apr 20 '22 at 13:46
I just retry, it's the same can it be because iI put this value in my scope : https://graph.microsoft.com/.default ? — Christopher Lessirard, Apr 20 '22 at 13:48
Try adding Group.ReadWrite.All permission and check if it works. Similar issue. https://stackoverflow.com/questions/65584822/to-do-api-the-service-is-not-available — Shiva Keshav Varma, Apr 20 '22 at 13:53
I add it but the issue is the same. The token doesn't take all permissions in the scope : "scp": "Mail.Read User.Read User.Read.All profile openid email" — Christopher Lessirard, Apr 20 '22 at 14:04

Looks like "TaskReadWrite" permission has not been added successfully , as we can see, there is no status Shown on screenshot you provided, could you please retry and add the "TaskReadWrite" delegated permission.
