Outlook won't close

Do you find Outlook running in the background on your task manager even though you have shut down the application? Here's something that might be causing the problem.

A corrupt *.SRS (send and receive profile file) will keep Outlook 2003 open. Find and rename the SRS - it's a hidden file located in the C:\Documents and Settings\username\Application Data\Microsoft\Outlook folder.

Use Windows Search to find the files (enable the advanced options to search all hidden files and folders) or paste this line into the Windows Explorer Address bar: %USERPROFILE%\Application Data\Microsoft\Outlook
