I have one email account on our server that will receive messages, however it says it is sending messages but they are not being received. I have checked the account added & deleted, checked all settings. Any ideas of what may need to be done next? All other email accounts are working fine.

if it is exchange server, you should check with your server administrator unless you are one. if it is pop mail, checked both smtp and pop server

Is there one particular email address that is not getting your messages???....or is it everyone you are sending to??? Are you recieving messages from everyone??? Or are you NOT recieveing messages from the same people you cannot send to??? Are you POP or Exchange??? Try setting up Outlook Express and see if everything works with it...if it does, then it's in your Outlook program...suggest remove and re-install... Good Luck Steve
