outlook / ISP email problem
I have an annoying problem, which is that when i send an email with an attachment, usually a picture of little size, it goes into the outbox.
Outllook then makes then sent sound, but mail does not go into sent items, although later i have discovered that it has been sent.
I have been repeatedly clicking on send/receive, and hear the sent sound again, but still it remains in outbox. Recipients have informed that they have received had repeated deliveries.
Is this an Outlook or ISP (using POP3) issue?
