There may be many reasons to delete an Outlook profile registry. A user may not need the profile account anymore, someone may no longer have access to the computer housing a profile registry, or it may simply be that the computer needs some memory freed up. Since Microsoft Outlook has the ability to house multiple profiles within one program, you can delete unwanted or unused profiles and retain the ones that are most important to you.
Turn on the computer. Click the "Start" button in the lower left-hand corner of the screen. Click "Control Panel" on the menu that appears.
Click "User Accounts" from the Control Panel menu. Click "Mail" from the options that appear to cause the "Mail Setup" dialog to appear.
Click on the third option, "Show Profiles," to bring up the list of all user profiles. Select the desired profile and click "Remove."
