Outlook is working fine. They can send and receive e-mails like normal. All other applications on the PC are working fine. Any idea what this error is for/from? I have not rebooted the machine to see if it happens again. I will do this at the end of the work day to limit downtime.

This error is a result of 3rd party add in, Mapi Labs.
Possibley "Duplicate Remover"

You can uninstall it or disable it in the Registry
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins
