And finally taking the two minutes to read the documentation tells me
that 'auth-source-cache-expiry is, by default, 2 hours:) Set this to nil
and these annoying requests for my password go away.

If anyone is interested, it seems that MS requires re-authentication of
the client every 6 months (this has nothing to do with emacs). This hit
me for the second time just after I sent my message yesterday that
everything was working great. So now I know the exact date (one year ago)
when I started using oauth2 with gnus :)
