Normally, for Office365, we'd suggest beginning your journey here:
https://sender.office.com/
And for "HotMail", we would suggest going ... here.
What to do in that case can be found by searching the archives of this ML. 😃
You will *NEVER* get anything aside from automated responses from Sender
Support because … that is the way the Lawyers have stipulated it.
And aside from pointing out the above noted two resources, there is very little
else you will get from posting to this mailing list because … *I* don’t scale.
Aloha,
Michael.

Subject: [EXTERNAL] [mailop] Need help with Microsoft S3150 and Yahoo TSS09 on
recently transferred /24
Could someone from Microsoft and Yahoo help me resolve this issue with
209.16.157.42?

Please contact your Internet service provider since part of their network is on

The /24 network that the server is located in was purchased and moved from ARIN
to RIPE on 2020-06-30 [1]. (Our new ISP was unable to supply more than 1 IPv4
address.)
The network hasn't been routed since 209.16.128.0/18 was advertised until
2017-12 by the original legacy IP holder [2].
None of the IPs are on any DNS lists, so I can only assume there's some kind of
"newly announced" restriction or "route origin changed" check that is
preventing it from being allowed to send any email.
Microsoft was previously returning 4xx for 47 hours and then either
disappearing the email or delivering it to Spam but now just returns 5xx. Yahoo
has always returned 5xx. Google are accepting messages.
The advice in the URLs in the error messages are meaningless because I have no
"outgoing emails" to review if they're never accepted. This domain has
SPF/DKIM/DMARC configured and the network is registered with SNDS/JMRP.
I don't get anything but automated or template responses from Microsoft or
Yahoo support.
I have 5 users in total (including myself) and don't operate any mailing lists.
This issue is frustrating when emails to Sky/AOL/Hotmail/etc. all bounce.
1. Aside from the creation date in RIPE WHOIS, here's the RIPE list of
IPv4 transfers for proof that this was transferred (and when):
