No, I haven't. What ports are those? I tried 465 but that didn't work either.Not sure if SSL StartTLS is supported, have you tried on the unencrypted ports ?
No, I don't think that two factor authentication is activated. I always login normally with my email and password and nothing else.Have you turned on two factor authentication for Microsoft account?
If yes you need to generate an app password, you can't use that of the account.
Hey, wow, that actually worked. Thank you!
