#407 Authentication window does not close

[H B]

I try to use O365Interactive mode. Default client-id does not work, so I use the client-id that I found that the browser uses. This client-id requires the redirect-uri to be that of ...landingV2, so I set it accordingly. I launch Davmail, and the pop-up Davmail window for authentication appears as planned. I go through log-in, including 2FA of a third party, and then, after log in is successful, instead of grabbing the needed token, I get into my O365 mailbox, inside the Davmail authentication window... As if Davmail does not "notice" that the login creds are there, grab them and close the window...

Is there a way for me to overcome this?

Or a way to scrape the token and enter it manually?
