This has been known to cause this problem, but Cloudmark did release a
fix.
Make sure you have it.

iTunes Outlook Addin (? didn't know iTunes did this)

Known to cause the described problem. Can be fixed by disabling indexing
the PST and then reenabling it to start the indexing over.

Just a quick follow up on this issue, I think I may have found a solution.
Because my Exchange server is so far away (both physically and via the
network), I have my e-mail delivered to my local PST file and have done this
for years. When I get a new computer and/or a new version of Outlook, I
configure it to use my PST file and all is well (usually).

Outlook 2007 has introduced a new file format for the PST file and after
some digging I found something which described a similar situation to what I
was facing and attributed it to not migrsting the PST file to the new
format. Here is the process to migrate a file:

So far so good this morning but I will keep an eye on it. The Outlook
process is rarely consuming any CPU cycles and my over all computer
responsiveness is much better.

Mike
