Because 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.
If you are using Outlook 2013 and newer, you cannot uninstall applications from the consumer subscriptions or retail versions. It's all or nothing. You can delete shortcuts to Outlook and set a different email client as default but not uninstall Outlook. (Businesses can use the ODT to selectively install Office apps.)
To Uninstall Outlook
Go to Control Panel, Programs and Features (Vista and Windows 7/8/10) or Add/Remove Programs in using Windows XP. Tip: type Add Remove Programs in the search field in the Control Panel to find it (works in all versions of Windows).
Locate the entry for your Microsoft Office application and choose Change. Tip: Click on Name at the top of the list of programs to sort applications by name then click on an application and type M to jump down to the programs that start with M. (If you have a lot of M's, type N and scroll up.)
Reminder: Outlook 2013 and newer cannot be uninstalled from the subscription version of Office. You can delete the shortcuts to Outlook and set a different email client as default.
If using Outlook 2010 and older, follow these steps to uninstall Outlook.
- Clicking Change 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, if Outlook is not visible.
- 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.
