Missing Email .. to user

Question asked by Merle Wait - 3/16/2026 at 8:51 AM

Unanswered

Have a user that is reporting that they are not receiving email XYZ ,, from a group-forward.

I can see that the email HAS been sent to the user's account.
However, I can't see/find the email anywhere.
I have the message ID...
MessageID: <4cw3rpuy8y-1@LRK1LLPIP1AAP10.prod.local>)
How can I track by message ID .. what folder in the user's account.. that this went to.. or where it ended up?

Did you check the delivery log? You can search by message ID or user. Make sure you have "Display Related Traffic" selected so you see everything that happened with the delivery. Should show the message being delivered and where it went and how. (E.g., if it was handled by a content filter, etc.)

Yes

First thing that I checked.
Shows delivered... but does not show anywhere in the user's folder... Not deleted not nothing.
The user has several examples.

'---------

I checked the user's content filter.. nothing in there reflects any actionable events for this email.

Would one be able to search by the messageID within the user's folder??

check if the user has any outlook rules that delete / move an email based on a criteria. I had that once a few years back!!

Yes it seems possible to use the API to search on a value for message id.

Use /mail/search with

jsondict['fieldsToSearch'] = ['Header']

and

jsondict['searchFieldValueMap] = 'your messsage id'

I have been experimenting with this function, but I do not yet have working code to share. The API has a significant learning curve, so if you want a quick answer, you might try to hire someone who has done this already.

Since the header data is not indexed, searching everywhere in a large mailbox might take slightly less than forever.
