This is caused by a misconfiguration of the account or the entire
domain in MS365. It can only be fixed on the Microsoft side.
Hello Bill,
I don't know anything about Microsoft Office 365 and email.
What does the error depend on?
Settings in Microsoft Office 365's "Exchange Online" area that control
which domains and addresses can receive mail. I can't say precisely what
the settings are, as I haven't had to touch that in quite a while, but
whoever administers the tenant account can fix it.
As you are apparently not in control of the MS365 tenant account, you
cannot fix it.
Is the server (sender-domain.mail.protection.outlook.com) running
directly at Microsoft and is it managed by MS, or is it running at an
IT system house that then manages the server for the recipient?
*.mail.protection.outlook.com machines are the exterior gateways for
MS365, operated by Microsoft.
