I've seen a couple of other threads on here regarding Outlook Express problems that are kinda similiar to mine, but since I don't even get a frozen start screen, my problem is a bit differnt, I think:
After installing XP sp2 a few days ago, I can no longer open Outlook Express. I do not get any error messages or anything -- but msimn.exe does start up and hogs anywhere from 40 to 98% cpu. And then nothing happens. The cpu usage goes up and down a bit, but no OE.
Every other program seems to work fine, including IE. I've tried running "sfc /scannow", as suggested by MS Support at http://support.microsoft.com/?kbid=318378 ("How to Reinstall or Repair Internet Explorer and Outlook Express in Windows XP"), but that didn't help.
I'm hesitant to uninstall and reinstall Outlook Express, because I'm not confident in my ability to preserve all the folders, email messages, and multiple identities I've got set up.
Any suggestions or instruction would be greatly appreciated. I wonder if sp2 is the direct cause of this -- and if so, if lots of other people will soon be having this problem as well.
Notes: I have AntiVir, Sygate, and ProtoWall installed (I've tried quitting out of all of these, but OE still does not open). I have the XP Firewall and AutoUpdate turned off. I have ALL current XP updates. I use Spybot, AdAware, and CWShredder frequently. There were no problems with OE until I installed XP service pack 2.
Key words: Outlook Express 6 freezes, Windows XP sp2 error
