Outlook API OAuth2 offline acces / permanent access using php

Question

I followed the tutorial below to get mail using outlook api. This works, but requires the user to login every time to give access. Is there a way to give permanent / offline

Answer 1

Here is the actual string you would need to append to the scope:

offline_access%20openid%20email%20profile

A basic example of a scope:

"openid+https%3A%2F%2Foutlook.office.com%2Fmail.read+https%3A%2F%2Foutlook.office.com%2Fcalendars.read+offline_access%20openid%20email%20profile"
