I have Exchange 2003 Standard edition.  Most clients are accessing it via
POP3 - using Outlook 2003.  Every time someone needs a new workstation or
remote computer setup their entire inbox is downloaded - but - it will get
so far then start redownloading emails.  I have to babysit every new setup
and go to OWA and delete the several emails that it stops on - then it
continues until it hits another email it deoesn't like - why does it do this
all the time.  One client every Expedia email caused this.  No other email
system I have used or setup does this....there is a patch mentioned for
Outlook but it's for earlier versions - can anyone shed some light on what
needs to be done to prevent this, why is their seem to be an incompatibility
issue between two microsoft products?
