    CPU usage (Outlook 2000)

    I am using XP and have noticed that the CPU is often grinding at 100% usage when Outlook is open. When I shut it down, the usage drops to 3% to 4% when nothing else is running. I am taking the CPU usage from the task manager on the Processes tab. I looked because the "find" command in Outlook was taking so long to process the folder. Any idea what Outlook could be doing? The .pst is almost 700 MB and I have 512 MB of RAM.

    Re: CPU usage (Outlook 2000)

    Do you have Word set as your email editor? That does tend to increase usage.

    Do you actually use the items in your *.pst, say, once a month? If not, you might consider archiving some of the older items. (I would recommend archiving manually; rather than using the auto-archiving option.)

    Have you tried Compacting your *.pst? Right-click Outlook Today and choose Properties|Advanced.

    unkamunka,

    Thanks for the response. No, I don't use Word as the email editor. What's strange is, that even when Outlook seems to be doing nothing (not sending or receiving or composing a message or even without any message open) the CPU usage verges on 100% - continuously. I have compacted the .pst and that hasn't helped. I guess its time I archived some of the stuff (a large portion of it). I'll repost with the results.

    Re: CPU usage (Outlook 2000)

    unkamunka,

    Well, I archived a number of old messages and blew down the .pst by half and still CPU usage is at 100%. The only recent change is how I am using Outlook. I have begun to use appointments and tasks (both with reminders in many cases) more than ever before. Since the high CPU usage began, I have noticed that when I "snooze" a reminder (usually to the next day), if I then close Outlook and open it back it up, the same reminder reappears as if it was never "snoozed" in the first place.

    What could Outlook be trying to do that it keeps the CPU so busy? Any assistance would be appreciated.

    Re: CPU usage (Outlook 2000)

    Assuming you have a default installation, try typing the following into your Run command at the Start Menu and then hit OK:

    "C:Program FilesMicrosoft OfficeOfficeOutlook.exe" /Cleanreminders

    If you have a non-default installation, change the part in quotes to where outlook.exe actually is. Alternatively, hit "Browse" in the Run dialogue and then navigate to the Outlook.exe folder. Then type (before hitting OK): Outlook.exe /Cleanreminders

    This should clear up stray reminders - which appear to have become clogged. (You may wish to make a note of any current reminders; just in case something is not properly reset.)

    Re: CPU usage (Outlook 2000)

    Unkamunka,

    Again, thank you for the suggestion. I ran "cleanreminders" but it hasn't helped. While Outlook is using 100% of the CPU when nothing else is going on, it does relinquish cycles when any other program is started. It seems to slow everything down somewhat but the biggest problem is using "find" in Outlook - it takes forever because Outlook is busy doing something else.

    Again, any help would be appreciated.

    Re: CPU usage (Outlook 2000)

    Outlook likes to compact its folders. You can initiate this process manually (if I recall correctly, you right-click the top level of the PST file in the Folder List, choose Properties, and there's a button (it could be under the Advanced Properties)). Other than that, I don't know what Outlook might be doing. Maybe it's bored and it's surfing the web? <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15>

    Thanks for the suggestion. Did that but it didn't stop the activity. I removed all tasks with reminders and appointments with reminders and the activity stopped. Seems strange that reminders should cause Outlook to thrash the CPU. Oh well, at least it sped things up.

    Perhaps I should have been more up to date on my research. MSKB 811167 should help you with the problem - which appears to arise with Service Pack3 and the Internet Mail Only mode.
