Firstly, I'd verify that Outlook 2003 sp2 has been installed.

Next, I'd be taking a look at KB 827349 and finally KB 816896.

Subject: [exchangelist] problems with outlook 2003 and secure pop3

Bit of an odd one, have several users backeast connecting to our
server. It has secure pop3 on port 995 and secure smtp on port 465, it
find for sending, and using my account on the exchange server, downloads
email work without issue. on their accounts I see the same problems they

The 2 users back east have XP Pro machines and Outlook 2003, upgraded
Outlook 2000, office 2000 is still installed, only the outlook portion
upgraded to 2003.  They are running the Trend Antivirus client from

The Exchange server is Exchange 2003 Enterprise with SP2 running behind
Fortigate FG60 firewall on a 1.5mb dsl connection.

On my test machine here, it's running Windows 2000, Outlook 2003 and the

Fortigate Forticlient (antivirus, firewall, vpn etc). When I pop email
my account, there are no issues, when they pop email, it times out after
few minutes. Sometimes it will download no messages, other times it will

download say 3 of 6 messages and hang on the 4th one.  When Outlook 
reconnects, they end up with duplicats, triplicates on the new messages.
the test I had one of the users do a few minutes ago, she ended up with
copies of some of the messages.

On my machine, logging into one of the users's accounts resulted in 3 or
copies of some messages.

For the first user back east, everything was working fine until about a
ago, he'd been successfully sending and receiving email without issue.
notes follow. This user had 955 messages in his inbox, but moving them
another folder and putting in say 2 or 3 messages in the inbox results
in the 
same problems.

The only thing I can think that was changed around that time was that
our IP 
address got on a SpamHaus blocklist (not our fault) as our ISP had been 
ignoring a prior SpamHaus block for the past year and it got escalated 
resulting in the entire class c we are in being blocked.  Other than
there have been no major changes to the server corresponding with the 
problems. Being that the ISP ignored the blockage, I've since got an ip
a non blocked class c and put the server on that and adjusted the DNS 
accordingly and mail is flowing, however the problem with pop3s is still

happening :-(
