My computer appears to be wanting to send an email and myh symantic keeps poping up saying that the email is unable to be sent because the address is not valid. the problem is that I do not know what the email is or if it is even email. my outlook express seems to be working with no problems. I cannot find anything that is causing the to happen, it appears to keep trying to send a message and the symantic keeps stopping it.
