I'm guessing you're using POP3 or IMAP as your server? Just a SWAG but
what is your automatic send/receive interval set to?

Using Outlook 2003 SP3. After having Outlook open for several hours it stops
sending messages and they just pileup in the outbox. Sometimes closing
Outlook and then restarting it fixes the problem, other times I have to
reboot.

My internet connection is stable and is working fine at the time that I cant
send. I can ping the SMTP server. I have tried a different SMTP server.

Any ideas?

Thanks
