How to Install 3rd Party Apps for users in Microsoft Teams

Microsoft Teams allows the use of third-party Apps to expand its functionality. The term “third-party” or “3rd party” refers to apps made by developers outside Microsoft, and range from project management systems like Trello, to graphical sharing apps like Adobe Creative Cloud. So in this article, I will show you how to install third-party apps for your users in Microsoft Teams.

How to install 3rd-Party Apps in Teams:

  • Firstly, open Office 365
  • Now click on the launcher. 
  • Select the option for “Admin.” 
  • From the list of admin centers, choose “Teams.” 
  • Click on the drop-down for “Teams apps.” 
  • Choose the option for “Setup policies.” 
  • now click on the “Add” option. 
  • Where it says, Installed apps, click on the option for “Add apps.” 
  • Click on the search box and input the name of the application you want to have installed. 
  • Click on “Add” next to the app name. 
  • Once the app is added, click on “Add” again. 
  • Scroll to the pinned apps section and click on “Add apps.”  
  • Use the search box to locate the newly installed app and then click on “Add.”

Some third-party applications may require users to input their Microsoft credentials to complete the setup. When users sign back into their Microsoft Teams account, they will have the application installed, and Microsoft will pin it on the user tab. 

The last few steps show how you can assign pinned applications to user accounts in Teams. The newly installed application can be pinned as default in user accounts if you want them to use it frequently. The general user assigned to this policy will not be able to override the changes made to the application. The user, on the other side, cannot uninstall installed applications from the admin center as a global policy.

What is the difference between apps, add-ins, and add-ons?

Apps may contain add-ons to improve and expand functionality. Add-ins are apps that you can integrate with other apps to produce cross-platform functionality. In Microsoft Teams, you can add apps (or add-ins), some of which may have add-ons, which we will look at in more detail later in this guide.

There are many excellent programs in the Microsoft Teams App marketplace, but you could discover that some of them are hidden from view. If this is the case, it often signifies that a Teams admin has not followed the following instructions to authorize the installation of applications.

The Microsoft Online Subscription Agreement does not control, own, or apply to third-party apps in Microsoft Teams. The terms and conditions of each third-party app govern how your company may use it.
