Question on Microsoft Hosted Exchange: There are a bunch of mail flow rules and we are troubleshooting an issue with a missing incoming message (from outside the org).

There is absolutely no trace of this message incoming from a message trace (Mail Flow -> Message trace) -- even a domain wide trace. Other emails ARE being delivered from this domain.

In case we have to audit our mail flow rules - would a rule (to block/delete a message) cause the message in question to not be shown in a message trace?

thanks!

Yes, any email processed by a transport rule will be available in a message trace. The message trace will show you the action taken on the email (such as being dropped).

Agree with what joeqwerty has replied above, I have done a test in my lab, the deleted mails show in message trace, look like blow:
