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 the app, you can coordinate events, create conferences, use other people’s calendars, and create meetings. It should be noted that, although Outlook is popular, there are a ton of similar services on the market that are also more successful and more popular than this email client.

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 system’s performance. Therefore, it is better to uninstall unnecessary applications in a timely manner. Also, if you encounter any problem in the application, reinstalling can help you solve this. In this article, we’ll show you how to completely remove Outlook from your computer.

How to uninstall Outlook on Mac manually

Any applications running on a Mac create special support files for proper and fast work. So when you decide to remove an app, you should remember to remove its service files as well. The same goes for Microsoft Outlook (2010, 2011, or other versions).

Follow the instructions below to completely uninstall the app with all of its cache, logs, preferences, and other service files.

  1. Quit the app and close all its related processes working in the background. You can use Activity Monitor for this.
  2. Microsoft Outlook selected in Activity Monitor window
  3. Go to the Applications folder and move Outlook to Trash. Move to Bin option selected for Microsoft Outlook application
  4. Launch Finder, click Go in the menu bar and select the Go to Folder option.
  5. Type ~/Library/ and press Enter. Library folder in Go to the folder window
  6. In the Library folder, find the service files of Outlook and remove them. In our case, we found service files in the following directories:

After deletion, we decided to check if there were more leftover files in other subfolders. We used a free application called Funter for this task. On the screenshot below, you can see that there are lots of the app’s service files, which are spread out in different locations and are not so easy to find manually. Therefore, we highly recommend using Funter, which finds any type of file by name, including hidden files in system folders and packages.

Once you’ve removed all leftover files, go to Trash and empty it.

As you can see, searching for service files manually may take a lot of time. The good news is that you can use the automatic method of uninstalling the app, which will take less than a minute!

How to uninstall Outlook using App Cleaner & Uninstaller

The automatic method requires using a special cleanup utility called App Cleaner & Uninstaller, which automatically finds all the service files of each application and allows you to remove them without leaving any remaining files.

  1. Download and run App Cleaner & Uninstaller.
  2. Find and select Outlook from the list of apps.

Please note that if you have already uninstalled Microsoft Outlook by dragging and dropping the program into the Trash, you can still get rid of its remaining system files in a matter of a few clicks.

To remove the remaining files of the Outlook app, launch App Cleaner & Uninstaller → go to the Remaining Files section → Select the files related to the Outlook app and click on the Remove button. Then just confirm the removal of all selected files.

How to reset Microsoft Outlook

As with any application on a Mac, Outlook can have problems. If it starts working incorrectly, closes suddenly, or shows an error, you should reinstall or reset it. To reset Outlook quickly, you can use the App Cleaner & Uninstaller app. Here’s how:

  1. Launch App Cleaner & Uninstaller.
