So my friend created an MSN / Windows Live account so she could talk to some friends. Apparently every time she tries to add a contact, and then send them a message, it doesn't work. I had her test this by adding my username, and it didn't pop up with the normal "accept and add?" dialogue box. I messed with this a bit further and got no where. I decided to test this in a controlled environment. I created a new Windows Live account. I then signed on to the account with meebo (a browser-based IM client) and tried to send myself a message. It didn't work. I'm lost at this point. I don't know what the problem could be at all. Any insight would be appreciated.
