Deploy Microsoft Teams with Office 365 Business

Currently, Microsoft Teams is a separate installation from Office 365 Business. But, starting in January 2019, Teams will be installed by default for new installations of Office 365 Business, starting with Version 1901. This includes new installations of Office on a Mac, starting with Version 16.21.

Existing installations of Office 365 Business won’t be affected at this time. Also, if Skype for Business is already installed, Skype for Business won’t be removed and will continue to function as before.

How to exclude Microsoft Teams from being installed by default on devices running Windows

If you don’t want Teams installed by default when you install Office 365 Business on devices running Windows, you'll need to use the Office Deployment Tool and use the ExcludeApp element in your configuration.xml file, as shown in the following example.

   <Add OfficeClientEdition="64" Channel="Monthly">
      <Product ID="O365BusinessRetail">
       <Language ID="en-us" />
       <ExcludeApp ID="Teams" />


Instead of using a text editor to create your configuration.xml, we recommend that you use the Office Customization Tool (OCT). The OCT provides a web-based interface for making your selections and creating your configuration.xml file to be used with the Office Deployment Tool. For more information, see Overview of the Office Customization Tool.

If you’re letting your users install Office 365 Business for themselves, such as from, you can’t exclude Teams from being installed by default.

If you want to remove Teams after it’s been installed, you can go to Control Panel > Uninstall a program. Select Microsoft Teams and then choose Uninstall. If you’re logged in with local administrator permissions on the computer, Teams will be uninstalled for all users. If you’re only logged in with user permissions, Teams is only uninstalled for that user.

What about existing installations of Office?

Existing installations of Office won’t be affected at this time, as long as you don’t make any changes to that installation, other than applying the regular feature and quality updates. But, if you initiate any other sort of installation on a device running Windows, such as installing additional languages or installing a subscription version of Project or Visio, then Teams will get installed by default as part of that installation process. In those cases, be sure to include the ExcludeApp element in your configuration.xml file, as described in the previous section, to exclude Teams from being installed by default.

Feature and quality updates for Microsoft Teams

After Teams is installed, it's automatically updated approximately every two weeks with new features and quality updates. This update process for Teams is different than the update process for the other Offices apps, such as Word and Excel. How often those apps get feature and quality updates depends on which update channel they’re on.

Microsoft Teams installations on a Mac

As of January 16, 2019, if you're using Version 16.21, or later, of the Office suite install package to deploy on a Mac, Teams will be installed by default.

If you don’t want Teams installed by default, there is an Office suite install package available that doesn't include Teams. You can also use the install packages for individual applications, such as Word or Excel. For links to the most current install packages, see Update history for Office for Mac.

If you’re letting your users install Office for themselves on a Mac, such as from, you can’t exclude Teams from being installed by default.

To uninstall Teams on a Mac, quit Teams by right-clicking the Teams app in the dock, then hold down Option and choose Force Quit. Open the Application Folder, select Microsoft Teams, and move it to the Trash.

What about Office 365 plans that don’t include Microsoft Teams?

Some Office 365 plans include Office, but don’t include the Teams service. For example, the Office 365 Business plan. In that case, a free trial version of Teams that’s valid for 1 year is available. Your users can start using it when they sign in to Teams. For more information about this free trial version and providing your users access to it, see Manage the Microsoft Teams Commercial Cloud Trial offer.
