Close Outlook 2003 but OUTLOOK.EXE and WINWORD.EXE in processes

[Guest]

I have about a dozen systems that are WinXP SP2 Office 2K3 fully patched and
when you close outlook it looks like it closed but next time you open it it
will not open. In task manager OUTLOOK.EXE and WINWORD.exe are present.
OUTLOOK.EXE is maxing out CPU. What is the problem or the fix?
