Assistance with Microsoft O365 Email Deliverability?

Fri Dec 10 13:42:50 UTC 2021

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
