Multiple retrievals of the same emails

Hi,
I hope someone can help me. Entourage just downloaded all my emails (about
2000) from the server - emails from December that I had already retrieved on
my computer. Why did it do that?!
It's the second or third time it's happened. I have to then organize by
unread - and delete all the emails it just got (and screen the ones that are
from the last 10mins).
Any ideas?
Cheers,
Alastair
