Microsoft mail delivery issue

Hi There,

If there are any Microsoft mail admins on the list can they please contact me ASAP. We’re having deliverability problems into you and all the usual tools don’t help with fixing problems, only diagnosing them after the fact.

Dear Paul,

I recommend subscribing and reaching out to the “mailop” mailing list. You may not see replies from the big mail operators in the archives, but I suspect a lot of relevant people pay attention to this specific list.

Kind regards,
