Message trace on Online Exchange

Question

Message trace on Online Exchange

Woody Chiu at RASI 251

Microsoft 365's Online Exchange is our primary email system for sending and receiving emails, and we use Outlook 365 clients.

A user said she didn't receive a crucial email that was sent from ******@ups.com. I went into the "Message Trace" on Online Exchange Admin Center and could not find anything.

In this situation, can I be 100% confirmed there was no such email reaching our email system at all, or there may be still some exceptions?

Thanks

Woody

Hi @Woody Chiu at RASI ,

Per my understanding, yes, you can confirm that the mail didn't reach your email system at all in this situation.

As indicated in the following official document, message trace can be used to track messages as they pass through your Exchange Online or EOP service. So, if nothing about the mail can be found in your message trace, basically it means the message didn't reach your Exchange online or EOP service.

The message trace shows me the Status of a couple of emails as "FilteredAsSpam". Where can I trace it down further to see why they are filtered?

Hi @Woody Chiu at RASI ,

As far as I know, this status could be caused by various factors and there's no comprehensive tool or way to directly find the reason.

Within the Message Trace, you can click on the message, expand the Message events section to see if there's any clue there. For example, sometimes a mail might be delivered to Junk Email folder because of a transport rule.

If there's no potentially relevant event in the message trace, other possible reasons could be that the sender email address is in the block list of the recipient's Junk Email Options, or the mail is just classified as junk by the built-in junk email filter in Outlook.

Then as we usually focus on only one question in one thread, considering that the question about "FilteredAsSpam" is a different topic what have been discussed previously, if you have further questions or concerns about it, it'd be best to open up a new thread for it. Thanks for your understanding :)
