I found references to typing speed when creating new emails in Outlook.
If this is simular to the problem you are having, try changing the format of
the new email message to Plain Text or Rich Text to see if this helps. HTML
format checks the blocked addresses in Internet Explorer and if that list is
very long you get very slow Outlook performance. There are some additional
suggestions if I'm on the right track.

Starting a few days ago, may be related to Windows/Office update that I
applied (not sure), my Outlook 2003 client in incredibly slow. Was working
fine for the past 6 months (bought a new computer in Jan 2007).

Anyway, I've tried reinstalling (uninstall/install), deleting profile, etc
and so forth - nothing works.

Outlook 2003 client is using IMAP to communicate with ISP email.

The only thing that temporarily fixes the problem is running "Detect and
Repair". Then Outlook is it's quite snappy self and functions fine... until
I close Outlook or reboot... then it is incredibly, unusable slow... starting
with "Sync Hierachy" message (wtf? I'm not using Cached Mode or Exchange
Server)

Anyway - something must be corrupt in the registry, eh? Why won't Detect
and Repair permanently fix the problem?

Any thoughts or help would be greatly appreciated

Thanks
