ErrorAccessDenied errors on calendars endpoint

Question

We are seeing "ErrorAccessDenied" errors on the /calendars endpoint with error message: "Access is denied. Check credentials and try again". I'm curious what is causing these credentials to be become invalid - is it due to invalid scopes?

Here are two samples of requests that failed with ErrorAccessDenied:

{
 client_request_id: "ca6ce25d-897c-408a-91bd-8b7a1bcd9d44",
 request_id: "94ef3617-b5b1-4169-8434-892fea45c897",
 x_ms_ags_diagnostic: "{\"ServerInfo\":{\"DataCenter\":\"East US\",\"Slice\":\"E\",\"Ring\":\"5\",\"ScaleUnit\":\"003\",\"RoleInstance\":\"BL6PEPF0000C787\"}}", :date=>"Mon, 21 Oct 2024 01:34:48 GMT"
}

{
 client_request_id: "f9d29055-0734-4eab-be7f-695a069d1210",
 request_id: "73f1158f-6232-4162-a13c-584618a1a54d",
 x_ms_ags_diagnostic: "{\"ServerInfo\":{\"DataCenter\":\"East US 2\",\"Slice\":\"E\",\"Ring\":\"5\",\"ScaleUnit\":\"002\",\"RoleInstance\":\"BN2PEPF000043D9\"}}", :date=>"Mon, 21 Oct 2024 16:23:42 GMT"
}

Answer

Hello Scheduling,

Thank you for reaching out to Microsoft Support!

Here is a similar case for your reference, please try to remove the excess permissions and keep only the necessary permissions, for example: Calendars.Read.

If this attempt does not work, please share the result of parsing a token in jwt.ms.

Hope this helps.
