Message could not be sent. The setting for your outgoing email server might need to be configured. Server error 450 Live mail error Ox800CCC79. Everything has been working fine until I accidentally sent out mail with an invalid address, the server roadrunner of course wouldn't accept it of course I had erased my messages from the sent and deleted files so I can not longer see them. Now instead of deleting them, Windows live mail continues to try and send them. This is not a Roadrunner issue, strictly Windows live mail. I'm thinking there is a copy on my computer in the program folder and that I may need to erase it there, but I can't seem to figure out how to open it to the view my mail from there. I am using Windows 7, any ideas? I have several different mail boxes they are all working fine, except the 2 that I have this problem with.
