What is Outlook and when to uninstall it

Microsoft Outlook allows you to work with corporate emails, create notes, filter them by attributes, save messages, and much more. The service also allows you to perform various other kinds of corporate tasks. With Outlook, you can coordinate events, create conferences, use other people’s calendars, and create meetings.

If you haven’t been using Outlook for a long time, we recommend that you don’t store it on your Mac computer. Unneeded applications take up a lot of your disk space, and a cluttered disk usually leads to various problems with your computer, including slowing down the Mac’s performance. Therefore, it is better to uninstall unnecessary applications in a timely manner. Also, if you encounter any problem in the Outlook application, reinstalling can help you solve this. In this article, we’ll show you how to completely remove Outlook from your Mac.

Important notes about uninstalling Microsoft Outlook from Mac:

  • Before writing this guide, we checked the information provided by Microsoft’s support page regarding uninstalling Outlook, which says that you can delete the browser by dragging and dropping it into the Trash. However, if you only do this, all its leftover files will still remain on your Mac and take up your disk space.
  • All applications that are installed on your Mac create lots of service files, which are located in the hidden Library folder and are occupying your disk space. When you delete an app by simply dragging and dropping it into the Trash bin, all of its system files are still left on your computer. To completely uninstall any application from Mac, you have to find and delete all its service files as well. In this article, we will explain how to uninstall MS Outlook completely.
  • We recommend that you follow the manual way only if you understand how the file system on macOS works. If you remove important service files by mistake, it can damage your system.
  • If you do not have time to explore the manual way of uninstalling Outlook from Mac, you can use a special tool called App Cleaner & Uninstaller.
