My son has a laptop and desktop using WindowsLiveMail on both computers. All ISP settings are identical on both machines. He has no problems sending email on the laptop,however, when sending an email from the desktop, it doesn't send until he exits the email program. Then a small window comes up in the middle of the screen that says "You have unsent mail in your OUTBOX - do you want to send now?" Then he has to click on 'yes' and the email is sent. This only happens on the desktop. This is a fairly new computer (purchased within the last year) and only recently set up for use. Anyone have any ideas??
