Email for our M365 tenant being delivered to Junk Mail Folder
I have one user in our org that has messages from two co-workers in the same tenant, with the same email domain, being delivered to her Junk Mail folder. As a test, I created a spam filter policy...
Messages are taking this route: Outlook Desktop -> Exchange Online -> Outlook Desktop
I have looked at the header using the header analyzer. I didn't find anything useful. Is there some header that I should focus on to gain more insight? I did some research on the "X-Microsoft-Antispam-Mailbox-Delivery" header thinking that maybe I could decode the value and find the "reason". After a long (but not exhaustive) search, it seems the codes aren't well documented.

Your starting point is the X-Forefront-Antispam-Report header. There is documentation available regarding the different components mentioned in that header.
Does this header already designate the junk folder as a target for message delivery?
- The X-ForeFront-AntiSpam-Report looks pretty clean:
SCL:-1; SRV:; IPV:NLI; SFV:SKI... PTR:;CAT:NONE;SFS:;DIR:INB;
Would this indicate this is likely an issue with the user's rules or possible Outlook Desktop categorizing as Spam?
