Outlook Data Files Locations
Note: It is important to back up e-mail files on a regular basis. Here is some backup information that may be helpful to you.
Viewing hidden files and folders:
Microsoft Outlook provides a Personal Folders Backup download. It backs up Outlook 2003 .pst files, which store everything for Outlook.
Microsoft Outlook 2003 may contain the following data store and configuration files that need to be backed up. Some of these files might be hidden folders.
To view hidden files and folders:
Click Start, and then click My Computer.
From the Tools menu, click Folder Options, click the View tab, and then click the Show hidden files and folder option.
For Windows 2000/XP:
Double-click My Computer on your desktop.
From the Tools menu, click Folder Options, click the View tab, and then click the Show hidden files and folder option.
Note: Your Outlook configuration may not include all of the following files. Some files are created only when you customize Outlook features.

You can delete the file.
