Wow at least you got a feedback,
which is more than i got the last 3 years
i have given up, my client know mail delivery to microsoft mailservice
is not guaranted, and i recomend to convince mailpartner for a change
to a more cooperative Mailprovider.
if i´m able to route microsoft mail via relayhosts on IP-ranges/AS
which are not blocked, but i wont spend much time anymore in
timeconsuming workarrounds.

They are probably ramping up rejection rates slowly, as suggested
here: https://dmarc.org/overview/
After I filed a support request with Microsoft, they got back to me
fairly quickly and said one of our IP-ranges was "a candidate for
mitigation". No other explanation offered. I don't see this being a
dmarc issue at all, but some sort of internal M$ "reputation list".
Thanks for everyone's suggestions!
