Turn on Microsoft Teams in your Office 365 organization
The new Microsoft Teams & Skype for Business Admin Center is coming soon! Starting in March 2018, we're gradually migrating settings to it from both the current Skype for Business admin center and the Microsoft Teams experience in the Office 365 admin center. If a setting has been migrated, you'll see a notification and then be directed to the setting's location in the new Microsoft Teams & Skype for Business Admin Center.
By default, Teams is turned on for all organizations. If you used Teams during the preview period, the setting stays the same as what you set during your Teams preview.
As an administrator for your organization, you can assign user licenses to control individual access to Teams, and you can allow or block what content sources can be used in Teams. See Administrator settings for Microsoft Teams for more information.
To learn more about managing individual licenses, read Office 365 licensing for Microsoft Teams.
Turn Teams on or off for your entire organization
Tenant-level control of the on/off status for Teams is temporary and will be removed by May 2018. At that time, access to Teams will be controlled via user-level licensing only. To learn more, see Manage user access to Microsoft Teams.
Sign in to the Office 365 Admin center with an account that has Global Administrator privileges.
Go to Settings > Services & add-ins.
On the Services & add-ins page, click Microsoft Teams.
To turn on Teams for the organization use the license picker and select each license then set the toggle to On and then click Save.
