OH NO! What a classic!
There are worse scenarios believe me!
There's a chance that she won't see it though. Why don't you ask her what email she is using these days - maybe you could say that you're expecting top important email and that your server is down. Ask if you could please use her email address and of course you will need passworld to retrieve top important mail. Delete message and done!
It's definitely been sent to her - it's in the sent box. The address definitely seems linked to cable TV. I have a feeling it's an address she used before she had a PC at home (do you remember when you could buy those keyboards that connected to your TV?!).
I've had no reply to it, but she works all week and would use e-amil at work if she needed something. But that's a great idea about asking for her e-mail address and password cha cha - what a crafty devil you are!!
