How do I stop duplicate POP3 emails using Internet Email service .

My primary emails reside on an Exchange 5.5 server mailbox. I am using
Outlook's Internet Email POP3 service to get my emails. What causes the
emails to be flagged as "never downloaded" and then I get a new copy of every
email from the Exchange server downloaded to my POP3 client? For example, on
my laptop, the Outlook program was open when the battery died. When I got
power back to the laptop, Outlook flagged my Exchange mailbox to download all
my email again, causing duplicate emails. I've seen this happen if the
name/ip address of the POP3 server is changed in the email profile, but I
didn't think the above example would caus this.

Sure - if OL was in the middle of sending/receiving when it was interrupted,
it never got a chance to send the "all clear!" message to the mail server,
to allow the messages there to be deleted.

Just curious as to why you're using POP to access your Exchange mailbox
instead connecting directly to it?

There is an issue of taking the laptop remotely to another location and
getting directly attached to the exchange server through the company's
firewall over a 56k dialup ISP connection. The other issue is that when I
use a local network RAS server 56k dialin connection, it hangs up the Outlook
program. That is why I am using internet email service instead of the
exchange server service. Does the "all clear" situation work the same for
Outlook Express as well as Outlook 2000 (that is using the internet email
service)?

Yep.

I suggest an OST file/offline file in Outlook, and VPN. Even over dialup,
this ain't so bad. And no POP needed.

I appreciate the tips. I'll try the VPN over dialup and do the OST in
Outlook. Thanks for your help.
