Cannot reply to emails

akulu11

I keep getting this message when replying to email... Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.mail.yahoo.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

I'm also always asked to enter my password when getting email, but then it's not accepted. The emails do continue to come in, bu=t I can't reply.

What are the settings? They should be: smtp.mail.yahoo.com, 465, SSL/TLS, OAuth2, email address. Same for the incoming, except imap.mail.yahoo.com, 993, or pop.mail.yahoo.com, 995. Is there a VPN in use?
