Because the Office update has a habit of installing updates for Outlook, even if you are not using it, and then setting Outlook as the default email client, it's recommended that anyone not using Outlook uninstall it.
Outlook 2013 cannot be uninstalled from the “Click to run” version of Office 2013. If you have a CD or full file download (some 600 MB), you can uninstall Outlook 2013 from the Add and Remove applet in the Control Panel. You can delete shortcuts to Outlook.
To uninstall Outlook:
Go to Control Panel, Add/Remove Programs (Windows XP) or Programs and Features (Vista and Windows 7/8).
Locate the entry for your Microsoft Office application and choose Change.
This will open the Office installation dialog with option to add or remove features or repair. You'll want to choose Add or Remove Features.
- Click Continue.
The Installation options tree displays a white box if all features are installed and gray if some features are either "not available" or are installed on first use. An X on the icon indicates not available, a 1 means it is set to install the first time you use it.
- Click the + (plus signs) to expand the directories.
- Click the little down arrow on the box to choose different installation options for each feature.
To uninstall Outlook, click on the button beside the name and choose Not Available, then Continue. This will remove all Outlook components. If you want to remove some features but keep Outlook, expand the directory and remove just those features.
To add features, select the feature then choose Run all from my computer.
The method for other versions of Office is similar. Some older versions use a checkbox – check or uncheck to change the installation options and grayed boxes indicate options under that feature are not installed.
