We are having a problem with email from a certain IP being rejected with
code FBLW15. We have gone through the normal channels but have received
no communication/acknowledgement from Microsoft at all.
When did you send the request in to delist@messaging.microsoft.com?

domain with *outlook.com MX records are rejected with the following:---

removal from this list please forward this message to
delist@messaging.microsoft.com (in reply to RCPT TO command)
---We have emailed delist@messaging.microsoft.com, with no response.
The IP in question is not showing up on any blacklists that we have
searched (mxtoolbox, multi-rbl-check, etc etc)Thanks

Aloha mai Nai`a.
This has happened to me twice this year. Both times I got an auto-response
fairly quickly, and a followup message within a week, and was delisted.
Never could get any info on why I was listed in the first place, though.

An MS engineer reached out earlier, gave me this:
https://postmaster.live.com/snds/addnetwork.aspx
Signing for and using that tool, I was able to pin-point the cause. You can also sign-up for their junk-mail feedback loop.
Hope this helps you next time!
Excellent, thanks!

Unfortunately, that's not going to work if the refusal reason was FBLW15
(or TBLW15).
You're not dealing with an issue on the Outlook/Hotmail side of the house.
If you had provided the last two octets, I might have been able to give
some advice earlier, but alas, everyone seems loathe to actually say which
IP is having issues.
Aloha mai Nai`a.
IP in question: 65.111.224.51
Not trying to hide anything, but seeing the posts with obfuscated IPs has rubbed off on me I suppose (for better or for worse.
I appreciate if you can help us out here.

Hi Robert,
I just experienced the same problem. It took 10 days before I got delisted without explanation.
My IP is clean, never blacklisted, SPF+DKIM+DMARC, present in DNSWL.org, etc.
Note that I had no issues for sending emails to @outlook.com. I only had issues (#FBLW15) when sending emails to Office365/ExchangeOnline users (i.e. @dowcorning.com in this case).
Best Regards,
Arnaud.
