Windows 10: Can't send email from Windows 10 app using either google or yahoo account

I can't send email from either Gmail or Yahoo account from the Windows 10 mail app. I can receive email on both accounts. I have removed and reinstalled the mail app, but this has not helped.

I have also run the troubleshooter and this has not shown any errors.

Unauthorized Emails from my account?

It is more than likely that your email account was hacked, either by a virus sniffing your password, or just simply hacked.

Either way, change your password on your email account. Unfortunately the damage by already be done. They already have your contact list and your email address associated with that contact list. There is nothing stopping them from sending out emails using their own SMTP servers to everyone on your contact list and claiming the emails are from your email address. They don't actually have to have access to your yahoo account or even any yahoo server to send emails to people that come from your address.

 

Forwarding Yahoo Email on Android Phone?

yeah i know what you mean, and assumed that would be a problem.
anything is possible. this is unlikely. there is no way to just change settings and make that happen.

you could set yahoo forwarding to send the email to gmail, i assume, no problem.
gmail MIGHT allow "from" field spoofing, check out google labs if it is not in the regular options.

other than that, short of some complicated scripting i don't see it happening.

 

email account hacked. please help

Then I suggest you use it.
