Recently, after doing a big PC clean (scans, disk cleanup, chkdsk, defrag etc.), Outlook 2002 has started playing up. As far as I can remember, the problems started after doing a disk cleanup (but don't take this as fact, i'm not completely sure that's when it started). Everything seems to be fine until I attempt to read a new email. As soon as I click on an unopened email, the program completely slows down. Alt-tabbing my way out works and it seems that nothing on the outside slows down while Outlook is trying to open the email. One thing to notice is that the CPU usage and PF usage do not shoot to high levels as I would assume to happen when something slows down like this. The last thing to mention is that eventually the email will open so the program hasn't completely failed.
Any ideas? Is this something to do with the clean I did with the computer, something else wrong with it or just the email server playing up.
