Microsoft Teams Public preview


Features included in preview might not be complete and could undergo changes before becoming available in the public release. They're provided for evaluation and exploration purposes only. The preview features aren't supported in Office 365 Government Community Cloud (GCC).

Public preview for Microsoft Teams provides early access to unreleased features in Teams. Previews allow you to explore and test upcoming features. We also welcome feedback on any feature in public preview. The public preview feature is enabled per Team user, so you don't need to worry about this feature affecting your entire organization.

As a companion to this article, we recommend using the Microsoft Teams Setup Guide when signed in to the Microsoft 365 admin center. This guide will customize your experience based on your environment. To review best practices without signing in and activating automated setup features, go to the Microsoft 365 setup portal.

Set the Update policy

Public preview is enabled on a per-user basis, and the option to turn on Public preview is controlled in an admin policy. Update policies are used to manage Teams and Office Preview users who will see pre-release or preview features in the Teams app. You can use the Global (Org-wide default) policy and customize it, or create one or more custom policies for your users. The policy needs to be assigned to specific users because it doesn't overwrite the global policy.

  1. Sign in to the Microsoft Teams admin center.

  2. Select Teams > Teams Update policies.

  3. Select an existing policy or select Add to create a new one.
