graph api url calling work in the explorer but doesnt with python script calls Error: 404,

Question

i am using microsoft graph explorer to call this url :
https://graph.microsoft.com/v1.0/users/******@outlook.com/messages
which return all the messages and everything is fine.
but when I use the URL call in my Python script i get :
Error: 404, Details: {"error":{"code":"ErrorInvalidUser","message":"The requested user '******@outlook.com' is invalid."}}

this is a personal email btw
I tried the api on my work email everything was fine but now that I created this account something gone wrong.
I changed the tenant ID to "common" but still facing the same issue

Answer 1

It might be because the Python script wasn't focused on the correct scope (Mail.Send)

did you ensure the correct scope was granted?

try decoding access token and check the scope value,
