Graph API unauthorized error for specific user only

Question

All the permission are given , this API is working fine for other users

Below is the screenshot of Graph explorer calling this API and getting unauthorized error

This API was working fine but after changing my outlook password because of some unwanted hack in the organizations

Is there any way to solve this problem and getting this issue in this API only other Graph API working fine

Answer 1

As per your description it seems it is blocked or not allowed by your security ops teams.

I would suggest register an app and use postman instead of graph explorer.
