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)

iTunes will allow synching with an iPhone. If you don't have an iPhone,
disable this or uninstall it.

Microsoft Exchange Unified Messaging
Microsoft Office Sharepoint Colleague Import Add-in
Microsoft Outlook Mobile Service

PDFMOutlook

Often unneeded. Try disabling this as well.

Windows Search Email Indexer

Known to cause the described problem. Can be fixed by disabling indexing
