O.P.  The following message could not be delivered to all recipients?
This is really starting to anger me! I have Windows Live, and have uninstalled/reinstalled Plus more than twice now. With the same results! It will not let me send messages to any of my contacts. I just get this error message -> The following message could not be delivered to all recipients! I really want to use Plus, because of all the awesome features, but it is useless without actually being able to message people. My connection is perfect. And I can send messages to my contacts when I just have Windows Live, without the Plus. I don't have any plugins, I just installed it. What is wrong with it?!
