I'm working on creating an Outlook Add-in using this architecture.

I'm trying to handle the scenario where Azure Active Directory Access Token expires. According to the official documentation, the token's life time is 1 hour.

So I was thinking about changing the token's life time as described in this question. But I cannot do so, as I don't have the right to edit Azure policies. Also, I believe there is a cleaner way to test this scenario.

How can I test/debug this scenario?
