Microsoft Outlook email - Sending large mails very slow

Hello,

A friend of my works with Outlook 2003 (not Outlook Express) on a HP
desktop pc with XP SP2 installed. When he sends a large email, it
takes
a lot of time before the mail was send. For example: it takes 2
minutes
to send a mail of 2 MB, about 6 minutes to send a mail of 6 MB... On
a
second computer, he does not have that problem.

The mailbox (pst-file) is about 476 MB. He uses ZoneAlarm en AVG
Grisoft but we turned off those with no results. Also with an new,
empty pst file, the system remains slow...

Disable e-mail scanning, especially outbound scanning, in the
anti-virus software. Turning off the option may not be the same as
disabling it. For example, some AV programs use and LSP (layered
service provider) in the TCP stack to intercept e-mail traffic. Even
if the scanning option is disabled, the traffic still must pass
through that LSP interrogator. See if e-mail scanning is completely
disabled in AVG (ask in an anti-virus group since someone there will
probably better know AVG). It may requires uninstalling that features
(and even having to reboot to get rid of the LSP).

Also, I don't know what version you have of ZoneAlarm (free, paid,
pro, whatever). Maybe it includes anti-spam features that also need
to be disabled. Obviously the size doesn't matter because it is slow
even with an empty PST file, so something is in your e-mail traffic
that is still interrogating it (or passing through it, at least) that
is causing the slow-down. You could try booting Outlook into its safe
mode ("outlook.exe /safe") so no plug-ins get loaded, or even try
rebooting into Safe Mode for Windows to see if something then no
longer loads that causes the slow-down.

AVG has lots of complaints regarding e-mail interferrence. You might
want to start looking around for other free alternatives. It also has
crummy coverage (only 92%; see http://www.av-comparatives.org/). With
AV scanning your e-mails, they have to be interrogated first. This
slows down when they get received (and can cause timeouts in the
e-mail client while it waits for delivery unless the AV program sends
out a bogus header at, say, 1-minute intervals) and will also slow
outbound e-mails to interrogate them.
