[*]Is your friend using a paid or free Yahoo email account?
[*]Is your friend using the web interface and if so what browser and version is your friend using
Probably Internet Explorer, no idea which version
[*]If your friend is using an email client to access Yahoo Mail then what email client is s/he using?
No, straight to Yahoo from browser
[*]Is this only happening with messages you send, and if so are you sending rich text or plain text messages?
Only messages I send. There are only the two of us on that yahoo account/address. Message type irrelevant: this started happening ~2 weeks ago, was fine up until then.
He can access the yahoo messages from his work computer. It only locks him out from the home computer.
I recently spent nearly an hour troubleshooting my daughter's Yahoo email account and after I found the cause of her problems, the best solution ended up being getting her off of Yahoo and onto another email provider.
I've tried emailing him to a gmail account, so that he can read and respond to me on yahoo. He hasn't tried that yet.
Thanks for replying Joe
