Outlook Dumps on Send/ Recieve

I am running Outlook 2003 (11.8010.6568) SP2. I pick up mail from 4
different POP3 accounts. Outlook has started dumping out of memory (just
dissappears) when it does a send and receive. I managed to track the culprit
to one of the accounts. When I remove that account- all goes well.

The ISP has made NO changes and one of the other accounts that causes no
issue is on the same serviere/ same domain. The account that seems to cause
a problem is my primary business account. I have tried deleting, rebooting
and reseting the account- but I get the same outcome.

This happened about a month ago and I got counsel here that the profile was
corrupt. By the time I created a new one, imported the data, reset my palm
and my copy of NEO (neither of which were to blame) it was hours of work. Is
there a way to root this account out fully or otherwise fix this so that I do
not have to reinstall everything again? Worst case, if I create a new
profile and import the old data, can I delete the old one and change the name
on the new one wtihout running afoul of anything in the bowels of the program.

any and all help appreciated!
