I've been having issues with my Microsoft 365 account and the support team mentioned that my server IP is listed by UCEPROTECT. I've heard some pretty negative things about UCEPROTECT, like they operate as a scam, where you can only get off the list by paying them. What bothers me is they don't provide a clear reason for the listing. I checked on MXToolbox, and the only listing I see is from UCEPROTECT. I'm really curious if Microsoft actually uses this list for their services.

I’ve managed to get listings off UCEPROTECT without having to pay a dime. Are you seeing a Level 1 listing, or did it escalate to Level 2 or 3? That might change your options.
It sounds like you may have gotten stuck with a random response from support. I've never encountered anyone mentioning UCEPROTECT being in use by Microsoft 365. Honestly, it's known to be a bit of a scam if you ask anyone in the know.
Just to clarify, are you sending emails via Exchange Online or do you have an on-prem server? Also, make sure your SPF and DMARC settings are properly configured, as they could affect your email delivery.
