Subject: Assistance with Microsoft O365 Email Deliverability? 


Hi NANOG'ers, 



Reaching out for help - having troubles with email delivery into O365 inboxes. Have done the requisite PTRs, SPF+DKIM 
work, domain reputation, RBL checks, etc. 


For some reason, this one is vexxing me. Anyone from Microsoft on the list that could lend a helping hand? 


Thanks, 
Tom
