Why is Outlook 2007 almost always synchronizing w high cpu..

You should also check that your polling interval is not less than 10 minutes

Thanks for the suggestions.

1. My error - system has 2GB RAM, not 1GB
2. No rules at all.
3. Re checking for new mails, I don't think this is the issue. When
Outlook is not synching, send/receive only takes a few seconds and new mail
is downloaded. Hmmm - perhaps the synching is not related to send/receive.
4. I don't believe I saw any add-ins in this Outlook, but I'll check again
in a day or two when I next see this client.
5. I'll check the polling interval.
6. Also next time I'm at this client, I'll check to make sure they don't
have a smartphone or similar device that Outlook might be trying to synch
with.

I'm open to more suggestions? I'll post the solution when I figure it out,
so others can benefit from it.

Thanks,

S

Virus scanner that integrates with Outlook is also a mail scanning addin.

Mystery solved! (At least, in my case).

I have a couple of hotmail accounts that access via Outlook as http accounts.
Well, it turns out that Outlook keeps building its .pst files for these
accounts, even though I've deleted the messaages.

Just close Outlook and delete these .pst files. Outlook will automatically
rebuild new (and much smaller) ones.

One of these puppies was over 9GB in my case.

Now all is good again.
