After sending mails with medium-sized MP3 attachments (2-3MB), the sent file still appears in my outbox, and if I close down LiveMail it tells me I have an unsent message and would I like to send it. If I say no it sends it anyway! Recipients have received up to 4 copies of the sent mail. This doesn't happen with mails that don't have an attachment. What am I doing wrong?
How soon after clicking to send do you close the programme? It takes a little time to prepare and attach even a 2-3Mb upload. In Outlook, it's sometimes necessary to go into Outbox and give a mail a little kick with the Send button, before closing it down.
