You don't have to remove the entire Microsoft Office 2013 software suite to remove Microsoft Outlook. By using the Change option in the Uninstall or Change a Program section of the Control Panel, you can choose the Office features you want to keep on your PC.
Press Windows-X or right-click the Windows logo in Desktop mode in Windows 8.1 to display the Power User menu and select Control Panel to open the utility.
Click the Uninstall a Program link in the Programs section of the Control Panel to view all programs installed on your computer.
Select the Microsoft Office 2013 program from the list and then click the Change button to display the Change Your Installation of Microsoft Office window.
To uninstall the entire Microsoft Office suite, click the Uninstall button instead of the Change button.
Ensure the Add or Remove Features option is selected and click the Continue button to view a list of all Office components. Optionally, you can choose to repair or remove Office.
If you select Repair, Microsoft repairs your copy of Office 2013. Select this option if your Office programs are malfunctioning and you receive errors.
Select Remove if you want to uninstall the entire Office suite from your computer. This option is similar to the Uninstall option in the Control Panel.
Click the disk icon next to Microsoft Outlook and select Not Available from the menu to remove the component from the Office 2013 suite.
To reinstall Outlook, select the Run From My Computer option from the menu. To install all sub-components and features of Outlook on your computer, select the Run All From My Computer option.
Select the Installed on First Use option to remove Outlook from Office 2013 but install it automatically on the computer when you attempt to use it for the first time. Various components remain on your computer and you may need the Office CD to install the program.
Click Continue to start configuring Microsoft Office 2013 and remove Outlook. The process usually takes less than two minutes. Although you can reinstall Outlook at a later time, you may lose your email accounts and customizations.
Close all Office programs to ensure the changes take effect. You don't need to restart your computer after you uninstall Outlook.
To delete the remaining Outlook files -- including the offline file folder which contains emails, calendars, tasks and other items -- delete the Outlook folders from the C:\Users\YourUsername\AppData\Local\Microsoft and C:\Users\YourUsername\AppData\Roaming\Microsoft folders.
