How to Uninstall Microsoft Outlook

Although Outlook is an email client distributed as part of Microsoft's Office package, many Mac users also have chosen it as their preferred way to deal with various emails, calendars, notes, etc. Those who no longer need Outlook and wish to remove it can do so in just a few simple steps.

Before proceeding to the uninstallation process, all active Outlook processes and the application itself must be closed. You make sure that this is the case via Active Monitor. Now, to get rid of the application, open the 'Applications' folder via Finder. Locate Outlook's icon and either drag it to the Trash manually or right-click on it and select 'Move to Trash.' This should uninstall Outlook but some related files might be present on the system. To remove them manually, users will need to have access to the Library folder that is hidden by default. Once inside the Library folder, find the following files and remove each one of them:

~/Library/Application Support/com.microsoft.Outlook
~/Library/Containers/com.microsoft.Outlook
~/Library/Application Scripts/com.microsoft.Outlook
~/Library/Caches/com.microsoft.Outlook
~/Library/Preferences/com.microsoft.Outlook

On Windows, the specific way to remove Outlook depends on which version users have installed as Outlook 2013 and newer cannot be uninstalled from the subscription version of Office. You can still set a different email client as the default one, though.

Type control panel in the search box on the Taskbar. Click on 'Uninstall a program' that is located right below 'Programs' or go to 'Programs' and then 'Programs and Features.' Type outlook in the search field located in the upper-right corner of the screen. Select the application and then click on 'Change.' This should open the Office installation dialog. Choose 'Add or remove features' from the available options. Now, locate Outlook, click on the button in front of it and select 'Not Available.'
