To that end, this guide will demonstrate how to uninstall and reinstall Microsoft 365 on your PC and other devices and, since it is a subscription-based service, how to activate it as well. Let’s begin.

Step 2: Install Microsoft 365
You can install or reinstall Microsoft 365 in a couple of ways.
Method 1. From the Microsoft 365 website
- Firstly, open the Microsoft 365 website in a browser. Click on Sign in and log in to your Microsoft account if you haven’t already.
- Enter your username and password and click Sign in.
- On the Microsoft 365 home page, click on Install apps.

- You can either install ‘Microsoft 365 (Office)’ which offers cloud-based access to the suite of apps all in one place, or you can just install the set of apps included with your Microsoft 365 plan. If you need access to the apps straight from your PC, you will invariably have to install apps that are part of your Microsoft 365 plan. So choose that instead. In our example, we have a Microsoft 365 Personal plan.
- Then click on Install.
- Wait for the files to download.
- The installation will be done automatically as well. This can take some time.
Once done, the Microsoft 365 apps will be installed on your computer.

- Simply open any of the installed apps.

And just like that, you would have reinstalled and activated Microsoft 365 on your PC.

FAQs
Let’s take a look at a few commonly asked queries about reinstalling Microsoft 365.
What happens if I uninstall Microsoft 365?
When you uninstall Microsoft 365, all the apps that are part of the Microsoft 365 are removed from your device. This doesn’t affect your license or subscription. You can always reinstall Microsoft 365 and gain access to your apps.
Can I reinstall Office 365 on the same computer?
Yes, you can reinstall Office 365 on the same computer, or any other device.
Can I reinstall Office 365 without losing the subscription?
Reinstalling Office 365 doesn’t have any impact on your subscription. Uninstalling only removes the family of apps that are part of your Microsoft 365 subscription plan which can become available after re-installation.
Will I lose Microsoft Office if I reinstall Windows?
Yes. Since a traditional Windows reinstallation process formats the drive, you will lose all your apps including Microsoft Office.
Can I have two versions of Microsoft Office installed?
Yes, it is possible to have multiple versions of Microsoft Office installed on your PC. Although Microsoft doesn’t recommend doing so, if you have access to the installation file for the previous version, you can run two or more versions concurrently. To avoid any issues with the different Office versions existing together, you should uninstall your current version first, install the older version, and then reinstall the latest version. Make sure to install the different versions in the order from oldest to newest. This works for all standalone Office apps as well except Microsoft Outlook in which case the latest version will overwrite all other versions.
Microsoft 365 is a family of amazing productivity apps that have served users for decades. Like any other app or set of apps, they can be installed and reinstalled with ease in more ways than one. We hope this guide served you in reinstalling Microsoft 365 on your device. Until next time!
