Microsoft Outlook 2010 provides users with a multifunction e-mail and personal scheduling platform. You can manage contacts, save notes, spell check messages, embed images, attach files and update your calendar. If you installed Microsoft Outlook 2010, but recently switched to a different e-mail service, you may find that Microsoft Windows still treats Outlook as the default e-mail provider. Whenever you click on a hyperlinked e-mail address, Outlook boots up. This annoyance can be alleviated if you remove Outlook 2010 from your system.
Click on the Windows "Start" button, indicated by the blue orb in the lower left-hand corner of your screen.
Click "Control Panel," then the Windows "Control Panel" pops open in a new window.
Click "Programs," then "Programs and Features." A list of all your software appears on screen.
Scroll the list, and click on "Microsoft Outlook 2010" to select it.
Click "Uninstall," and a prompt appears on your screen, asking if you're sure about deleting the program. Click to confirm the software removal, then a progress bar appears, and Outlook 2010 is uninstalled once the progress bar fills. After uninstalling Outlook 2010, some lingering backup and draft message files remain by default. To completely remove all of these old Outlook files, you need to remove the Outlook folder.
Close all open windows and click on the "Start" menu again, and click "Computer."
Click "Desktop" from the left-hand task pane.
Double-click on your user name from the list of folders and files.
Double-click on "Application Data," then click on "Outlook" to highlight this folder.
Press the "Delete" key on your keyboard, and a pop up message asks if you're sure about the deletion. Click "Yes" to completely remove the last remnants of your Microsoft Outlook 2010 installation.
