XP-Pro, Outlook2003, mails often remain in outbox and resends

[excursion]

I use Win-XP-sp2, Office2003, F-secure.
I often experience that when sending e-mails, the e-mails stays in the
outbox, and resends several times without me knowing it.

Other problems that migth be related to the same error are:

I-explorer often do finish the search for new pages on the internet. I often
have to refresh several times or even restart. Most often this occurs when
serching for pages 2 -3 levels down in the "structure", and/or https pages.

Most times when downloading files from the Internet, the process stops
completely or goes very slow.

I have tried Mozilla Firefox, but the problems remain the same.
The system is scanned for viruses and spy ware every day.

Are there anyone who have any suggestions to what causes this problem(s),
and how to fix this?

I think it's a symptom of the problem he's describing and not intentional.
His problem sounds more like a networking issue and not an Outlook issue.
