I have been waiting to post this until I could get permission, which I just have. We have been working with a sender having the issue of Google (Gmail) rejecting all email coming from their Microsoft account, giving a "domain reputation issue" response. We knew it was an issue specific to Microsoft sending to Gmail, as in fact the same domain had no issue at all delivering to Gmail from other platforms, we had gone over their authentication with a fine-toothed comb, etc., and posited that the "domain" referenced in the rejection notice was actually the *Microsoft* domain, and not this sender's.
A few days ago we received confirmation of that from the Google side: "I can see that you are sending the emails from the Outlook server. Previously Outlook was using IPV6 to send the emails then all of the emails were marked as spam just because of the reputation. And due to that past interaction, whatever emails coming from Outlook IPV6, Gmail has detected them as spam and just to protect our end user, they are rejecting the emails." And now, just a few minutes ago, from Microsoft: "Our teams have been in contact with the Google team over these issues, apparently it was affecting some other users as well." This of course doesn't mean that the issue is resolved, but it does mean that both sides are acknowledging the issue, and we have noted that the sender with whom we were working (which is what led to these dialogues with Google and Microsoft) is now able to deliver to Gmail.
