    Outlook using 100% CPU (O2K SR1)

    I read in the last few weeks about Outlook using 100% of the system CPU... well, mine has started doing this, without doing any of the updates described. Unfortunately I can't get into Outlook to review the archived WOW to see if I can fix the problem. I don't know what may have changed, I have not updated Outlook or any Office component for about a month or so. I appreciate any help!

    if it's the same problem - start outlook with the /cleanreminders switch.
    other fixes include creating a new profile or deleting outcmd.dat.

    did you install any software or windows updates right before it started doing this?

    I havn't updated anything for about a month. This problem started just a few days ago without anything I know I changed. I am not familiar with any of the fixes you suggested. I don't use Outlook for any scheduling, so would the 'reminders' switch affect anything? and what affect does deleting the outcmd.dat file have?

    /cleanreminders deletes the reminder cache (a hidden folder in the mailbox) and outlook rebuilds it. if you have any reminders set - for tasks, calendar etc, you should try the switch.

    outcmd holds custom toolbars - outlook will rebuild it but if you added any toolbar buttins, you'll lose them.
