I am trying to setup Yahoo mail to be read on my desktop Outlook 365 using IMAP (win 10 PC). I tried letting Outlook use the automatic setup but it continues to fail. I then tried numerous setting suggested on various web sites which also did not work.
If you have it working on your system, I would appreciate you telling me the settings
If everything is set up correctly, try generating an app password. To do so, go to your security settings. Click Generate app password and choose Outlook Desktop > Generate. Then use that generated code instead of your Yahoo password in Outlook.
