I've written a demo app that retrieves and displays a user's mailfolders and mails from Outlook 365, and allows them to send an email the same way, all using Microsoft Graph.

In order to use Graph, I had to get an Entra AD tenant account from Microsoft.

The app works flawlessly on my machine (and yes, I know how cliche that sounds), but when I deploy it, I get nothing but an unspecified 500 error.

I believe the problem is due to my app not accessing the Entra AD account (secret, tenant, client, etc). As part of the creation of the app, I set those on my computer.

When I created a KeyVault on Azure, it didn't provide any way to enter the secret/tenant for Graph. Only to create a new one.

What I have tried:

I have tried using

app.UseDeveloperExceptionPage();

, and I have tried turning on logging in the web.config. Nothing changes, and no log is generated.
