Outlook / Office 2003 SP2 High CPU Usage After Upgrade.

[zeio]

Please help, SP2 causes me super high CPU usage and slows outlook to a
crawl.

- Outlook 2003 SP2 in Exchange mode, non-cached.
- Server is SBS 2003 SP1 with Exchange 2003 SP1
- One PST driven mailbox, one exchange mailbox in non-cached mode, very
basic setup.

In outlook 2003 SP1 BEFORE and AFTER SP2 un-install, everything is
super fast.

In outlook 2003 SP2, everything takes forever, CPU usage is super high,
when refreshing folder, cpu is 90% on P3-866Mhz, everything is slow.
Exchange Server logs show nothing abnormal. Nothing.

Un-installed SP2 and all of office, installed fresh from SP1
administrative share, everything is super fast and normal again.

No error messages, no disabled broken plugins, no obvious faults, just
everything is slow as hell.

Please help.

Hi,

I've had exactly the same prolem today with standard Exchange 2003
Server with SP1, Cached Exchange and RPC/HTTP/s.

When Outlook was connected and the "Waiting to update folder" should
change to e.g. updating Outlook froze and took all available CPU.

I've tried virtually everything from uninstalling plug-ins, disabling
cached exchange to using TCP/IP and much more.

The problem was finally solved when I deleted and re-created my
profile (I also deleted the .OST file which I suspect was the cause of
the problem)

Best regards

We have noticed this as well.

We run Windows 2000 and Citrix. With Office 2003 we normally can get 60
- 70 users per server. Now we have installed Office 2003 SP2 on the
server it is more like 30 with CPU hitting 100%. It you look in the
task manager it is the Outlook processes that are taking all the CPU.

Dennis Lundtoft Thomsen,

You said that you deleted the profile and then the OST file to fix this
issue. I started by deleting the entire user profile and then re-creating
it. However, after adding the Exchange account to Outlook I still had the
same issue (very slow going between folders, calendar, etc.).

I then looked for the OST file and could not find one. I searched the
entire hard drive. Do you have any other advice?

Hi Matt,

You can find the ost file at -

C:\Documents and Settings\%username%\Local Settings\Application
Data\Microsoft\Outlook

It's a hidden folder, so that might explain why you cant find it !?

Best regards

Dennis Lundtoft Thomsen,

I apologize. I didn't realize what an OST file was. We use PST for
archives. However, deleting the PST had no impact.

We aren't running in Cached Exchange Mode, another reason we don't have
additional OST/PST.

Any other ideas?

Yes I am hainv ghe same exact issue.

After doing much research, it appears that this problem of CPU spikes is
caused by using Word as your email editor in Outlook. If you turn off this
feature, the problem stops.

Has anyone figured out how to correct this?
