OLEXP: Hotmail Messages Are Downloaded Twice

Also, reportedly you should turn off the option to open in the Inbox
and/or the option to send and receive at startup.
If a POP3 account::
If you never complete downloading all the existing e-mail messages from
a POP3 mail server, the next time it will start over from the beginning
and send the messages that you may already have. This is by design of
the POP3 mail protocol. As a fail safe, the server always assumes on a
lost connection that the mail client crashed and lost all messages from
that download.
Some possible causes of problems downloading mail messages:
- You may have a very large message to download, or one that is causing
problems for your mail program. You may be able to use Telnet to look
at your server mail box and optionally get rid of any problem message.
You can find these Telnet instructions at
http://pages.prodigy.net/michael_santovec/pop3telnet.htm
Or your mail service may offer a web interface that would allow you to
delete the problem message. If not, you might be able to use
http://mail2web.com or http://www.mailstart.com for this function (if
your ISP allows outside access to their POP3 mail server).
- The POP3UIDL.DAT (IMN or OE4) or POP3UIDL.DBX (OE5+) file may be
corrupted. This is used to track previously downloaded messages when
you leave messages on a POP3 server (Tools, Accounts, Mail, Properties,
Advanced). However, the file gets updated even if you aren't leaving
messages on the server. Delete the file with Outlook Express or
Internet Mail closed. (On Win2000 you need enable the display of Hidden
or System files in the folder options and XP you need to use the
advanced options to find Hidden or System files.) The next time all
mail on the server will be downloaded. But after that the file should
function correctly again.
- The POP3 mail server is having problems.
- Anti-virus program scanning e-mail as it downloads. Increasing the
Server Timeout at Tools, Accounts, Mail, Properties, Advanced might
help. Or you may need to disable the anti-virus software from scanning
e-mail.
- Outlook Express 5 Downloads Same E-Mail Message Multiple Times
http://support.microsoft.com/?kbid=245620
OE 5.00 has problems with leaving mail on the server when you have
multiple POP3 accounts on the same mail server. (This may be fixed in
5.01 and later.) If you use the IP address for the POP3 mail server
name in the second account, that seems to be a workaround. If you have
more than 2 POP3 accounts on a server, you can use the C:\Windows\HOSTS
file to make up alias names for the POP3 mail server that point to the
appropriate IP address.
