How to enable Developer preview and Public Preview in Microsoft Teams

Public Preview and Developer preview provides early access to unreleased features in Microsoft Teams. You can test new features before it becomes general availability (GA) and analyse it to see if the new features will be useful for the organization. Preview feature can be enabled per Team user or for the whole organization. You can use Teams Update policies for enabling the preview feature setting. Its best if you create a separate Teams update policy and apply it to few users who will be testing the new features for example IT Administrators.

You can enable the preview version of Microsoft Teams by Launching Microsoft Teams Client –> Click on three dots next to your picture on top right hand side corner of Teams Client and then click on About and from the list of options presented you should see Public Preview and Developer Preview option. If you are not able to see these options then probably its not enabled for you.

In below screenshot, we can see that there is no option to enable Preview features from Teams client.

If the user is logged on to the Teams App, they may need to logout and log back in to get the new policy. If the new options are not immediately available then wait for few hours and then try again.

The options are available but not yet enabled until you click on it. Once you click on Public preview or Developer preview option, Teams client will restart and a prompt will be shown for accepting the risk which the unreleased feautres might bring as they are still under development. Click on Switch to public preview which will restart Microsoft Teams Client.

Now, if you go back to the Teams Client –> Click on three dots –> About –> You can see that Developer Preview and Public preview options are enabled.

Conclusion

Enabling of Teams Preview feature is useful for admins and power users who want to test Teams features which are not yet Generally Available. By default the policy does not allow users to enable preview version of Microsoft Teams client. A Teams update policy can be created and applied to select group of users who wish to participate in the testing of unreleased / currently under development features. As we have seen in this blog post, its very easy to enable the previous feautres for the users. Please note that after you have created the policy in Teams Admin center, it could take some time for the policy to get affected.
