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
