Keyboard slow in Outlook 2003

[Wordsmith2006]

A few days back, for no discernable reason, I experienced a long delay
between pressing a key and the display on screen. This only occurs in Outlook
2003. All other Office programs and Internet forms work fine. I changed from
HTML to Rich Text and it still slows down. Then it works perfect for a while
then starts slowing down again. The only way I can use it consistently is to
make WORD my text editor, which I do not want.

I have defragged, cleaned my hard drive, cleared history and cache, and
rebooted several times, but the problem persists. Any ideas? I have used this
since the release of Office 2003 with no problem.

Outlook 2003 and previous use Internet Explorer to render HTML. A recent
security update for IE sports a new anti-phishing mechanism that also scans
the sites listed in Restricted Zones. Sadly due to Outlook's IE dependancy
it will check it for Outlook too well composing new emails EVERY TIME you
type a character which can result in poor performance in Outlook if you have
a lot of sites added to your restricted zone. I have reported the issue to
Microsoft already a while back. The current workaround is to keep the amount
of sites listed in the Restricted Zone to a minimum.
