Evolution with business account (oauth2)

I have now also tried to build a react app.

https://learn.microsoft.com/en-us/entra/identity-platform/sample-v2-code?tabs=apptype

But also this behaves same. I get the popup to login but when I do so the result is an empty white page.

Please see above what I have tested so far.

When I enter this URL (I put in my tenant and application ID) I am asked to login with my organisation and when I do so I only get a blank white page without any error or confirmation.

https://login.microsoftonline.com/<TENANT ID HERE>/oauth2/authorize?resource=https%3A%2F%2Foutlook.office.com&response_type=code&response_mode=query&prompt=admin_consent&client_id=<APPLICATION ID HERE>&redirect_uri=https%3A%2F%2Flogin.microsoftonline.com%2Fcommon%2Foauth2%2Fnativeclient

I have tried all this without success.

Also I have followed this guide and created my own application.

https://wiki.gnome.org/Apps/Evolution/EWS/OAuth2#Troubleshooting

Evolution shows this error message: 

The reported error was “Could not connect to autodiscover.frank-ansari.de: Connection refused”.

But the CNAME for autodiscover is set available.

I checked this but this also fails.

After login I get this window:

Then there is nothing.

In Azure I see this URL for my application.

https://outlook.office.com/EWS.AccessAsUser.All

I put application and tenent ID in here.

This gives this error:

I am still stuck with this.

Please consider this:

1. Check Evolution Version: Ensure you're using the latest version of Evolution and the evolution-ews plugin. Compatibility issues often arise with outdated versions.
2. OAuth2 Configuration:
• In Evolution, go to Edit > Preferences > Mail Accounts.
• Select your account and ensure the authentication method is set to OAuth2.
• Verify that the server settings match Microsoft's requirements:
• Server Type: Exchange Web Services
• Host URL: https://outlook.office365.com/EWS/Exchange.asmx
3. Azure AD Permissions: Sometimes, business accounts require specific permissions in Azure Active Directory. Ensure that your account has the necessary API permissions for email access.
