Okay, here's the deal. I've got a friend who can talk to people on MSN, but the majority (most) people who he IMs and try to IM him back get 'The following message could not be sent to all users'. Now, before anyone asks any questions, the excuse he has for not posting this himself is because he's just frustrated right now.
Anyway, the point is, this has happened to him before, but it's always been him who couldn't talk. This isn't just one person that can't IM him. It's like. . . Everyone he tries to talk to, and only restarting MSN works, and even then, it only works for a short while, and then the message comes up again. Mine and his question is; Has this happened to anyone else, where everyone you try to talk to can't IM you and gets that message, and possibly know how to fix it?
Anything is appreciated. Thanks.
