Did you have Microsoft tech support contact you? I have sent over a ticket and they are setting up a time to talk with me and work on the issue. All of my emails to yahoo and aol are still bouncing back to me. I have tried plain text everything. Nothing is working.

2024-01-17T18:36:20+00:00 I am having the same issue for more then a week, I've emailed to two separate yahoo accounts and the emails are bouncing back after 24-48hrs. I had one recipient on the phone troubleshooting in real time and nothing comes through. I get the bounced email notice the next day. I also sent an email from my Gmail account to the same yahoo account while we were troubleshooting and the Gmail email went right through. It seems yahoo is flagging emails from Microsoft servers (in my non-techie opinion). I'm on Windows 11, version 23H2 updated 11/11/23.
