Hi David, Can you share the headers such as X-Forefront-Antispam-Report:, X-Microsoft-Antispam:, X-Exchange-Antispam-Report-Test:, X-Exchange-Antispam-Report-CFA-Test:, X-Microsoft-Antispam-Mailbox-Delivery:, and whatever else relevant?
BTW this tool https://testconnectivity.microsoft.com/ could help visualize the headers more easily In my cases of undoubtedly misplaced emails (in junk folder instead of inbox), I have some funky things such as: - BCL:8 (all indicators of complaints, including those provided by SNDS and JMRP, being at the lowest for months, I don't explain this score) - SFV:NSPM (so the content filter said "non-spam") - PCL:0 (nothing weird here) - SCL:1 ("Non-spam because the message was scanned and determined to be clean") - SPF, DKIM and DMARC results are "pass", MAIL FROM:, From: and d= domains are aligned - X-Microsoft-Antispam-Mailbox-Delivery: contains "RF:JunkEmail;OFR:SpamFilterAuthJ;" for the case when it's in junk folder When these emails reach inbox (because they sometimes do), the _only_ notable difference is that this last header doesn't contain these RF: and OFR: information. There's just no mention of it. The rest is identical, even the BCL:8. I'd be happy to gather similar cases so we could build a bigger and better argumentation (the objective being to ease Microsoft's job in fixing this), so don't hesitate to share on or off list.

We're a small ESP that focuses on serving the small business market. In Return Path, we're seeing great inbox placement at Gmail, Yahoo and AOL, and terrible inbox placement at Microsoft. We use SNDS and JMRP already and neither seem to help. It doesn't matter whether I do a seed test from a green IP, yellow IP, or red IP, they all run into the same filtering issues. Even my seed test emails going out of transactional-only, always green IPs run into filtering problems. I've opened several support tickets with Microsoft - SRX1407027597ID is the latest - but they seem completely unable to help. They just tell me that there's nothing wrong with the IPs, or that the filtering is due to SmartScreen, etc but provide nothing actionable that would help us fix the issue and improve our inbox placement. We already monitor things like hard bounce rates, complaint rates, spam filter analysis, spam trap hits, etc. for all of our customers and take action on bad actors in our network. So far that's been working for us everywhere else, but not at Microsoft. Any ideas of what we can do, or who to talk to, to get better inbox placement at Microsoft?
