Microsoft Teams is the chat-based workspace in Office 365. It's the hub for team chats, calls, meetings, and private messages. Microsoft Teams is extensible and customizable, and it's secured and standards-compliant to make sure your organization's most sensitive collaborations are private.
Turn on Microsoft Teams for your organization
Use the Office 365 admin center to enable and configure Microsoft Teams for your organization.
You may also be interested in the deployment advisor for Microsoft Teams, which gives you self-guided support for setting up Teams in Office 365. As you select the features and options you want to deploy, the wizard builds a step-by-step setup plan that’s customized to your needs. The wizard won’t change any of your organization’s settings or data. For more information, see Teams Deployment Advisor.
Important: By default, Microsoft Teams is enabled for all eligible Office 365 commercial suite users with the appropriate license assignment. All settings are tenant-wide and affect everyone in the organization who has an active license for Microsoft Teams. For Office 365 Education suite users, Teams is enabled by default for all eligible users with the appropriate Faculty and Staff license assignment. You can use the Office 365 admin center or Office 365 PowerShell to manage user access to Teams via license assignments. For more information, see Manage user access to Microsoft Teams licenses.
Sign in to Office 365 with your work or school account.
Choose Admin to go to the Office 365 admin center.

Microsoft Teams URLs and IP address ranges
If your organization restricts computers on your network from connecting to the Internet, refer to Office 365 URLs and IP address ranges. This article lists the endpoints that you should include in your outbound allow lists and the Internet Explorer Trusted Sites Zone of client computers to make sure computers in your organization can successfully use Microsoft Teams in Office 365.
Install and use Microsoft Teams
After Microsoft Teams is turned on for your organization, you're ready to install and use it. Download the installers for the Microsoft Teams Windows and Mac desktop clients from https://teams.microsoft.com/downloads. Admins can also download the installer and then distribute it through client distribution tools.
Note: After the client is distributed by admins, later updates happen automatically through the service.
If end users have the rights to install applications on their desktop, they can install the application from https://teams.microsoft.com/downloads. To access the web client, users can go to https://teams.microsoft.com. Users with mobile devices can download the Microsoft Teams app from their mobile platform's app store.
Microsoft Teams is available on Windows (Windows 7 and later) and Mac desktop (Mac 10.10 and later). It's also available on iOS v9 and later (iPhone and iPad), Android 4.4 and later, and Windows Phone 10.0.10586 and later. Microsoft Teams is not available via a mobile web browser; it's available only through the mobile app.
Microsoft Teams supports the web client on Microsoft Edge 12+, Internet Explorer 11+, Firefox 47.0+, and Chrome 51.0+. Users who try to open the Microsoft Teams web client on Safari are directed to download the desktop client. Support for Safari is coming at a later date.
Manage user access to Microsoft Teams licenses
As an Office 365 administrator, you can manage user access to Microsoft Teams licenses via the Office 365 admin center. You must be an Office 365 global administrator or user management administrator to manage Microsoft Teams licenses.
To prevent a user in your organization from accessing Microsoft Teams, remove the Microsoft Teams license for that user. After you turn off a license, that user can't sign in to Teams.
You manage Microsoft Teams licenses the same way you manage any other Office 365 license. Sign in to Office 365, go to the Office 365 admin center and, on the Users > Active Users page, assign or remove the Microsoft Teams license. See Assign licenses to users in Office 365 for business and Remove licenses from users in Office 365 for business for more information.
In addition to using the Office 365 admin center, you can also use Office 365 PowerShell to assign and remove licenses. To assign a license to a user, use the following syntax:
Set-MsolUserLicense -UserPrincipalName "<Account>" -AddLicenses "<AccountSkuId>"
The following example assigns a license from the litwareinc:ENTERPRISEPACK (Office 365 Enterprise E3) licensing plan to the unlicensed user firstname.lastname@example.org.
Set-MsolUserLicense -UserPrincipalName "email@example.com" -AddLicenses "litwareinc:ENTERPRISEPACK"
For more details and examples, see Assign licenses to user accounts with Office 365 PowerShell.
To remove licenses from an existing user account, use the following syntax:
Set-MsolUserLicense -UserPrincipalName <Account> -RemoveLicenses "<AccountSkuId1>", "<AccountSkuId2>"
The following example removes the litwareinc:ENTERPRISEPACK (Office 365 Enterprise E3) license from the user account BelindaN@litwareinc.com.
Set-MsolUserLicense -UserPrincipalName firstname.lastname@example.org -RemoveLicenses "litwareinc:ENTERPRISEPACK"
For more details and examples, see Remove licenses from user accounts with office 365 PowerShell.

Turn this feature on so that users can send an email to a channel in Microsoft Teams, using the channel email address. Users can do this for any channel belonging to a team they own. Users can also send emails to any channel in a team that has adding connectors enabled for team members. And, even if a user doesn’t have permission to create a channel email address, if someone who does have permission creates that address, the user can access it from the <more icon> menu for that channel.
Note: To find the channel’s e-mail address, click …More options next to the channel name and then select Get email address.
To turn on or turn off support for email integration, click or tap the toggle switch next to Allow users to send email to channels to Off or On, and then choose Save.

User settings by license
In User settings by license, you can turn on or turn off options in Teams and channels, Calls and meetings, and Messaging.
Teams and channels
A team is designed to bring together a group of people who work closely to get things done. Teams can be dynamic for project-based work (for example, launching a product or creating a digital war room). Or, teams can be ongoing, to reflect the internal structure of your organization.
As an admin, you can manage team owners and members by using the Groups dashboard in the Office 365 admin center portal. In the Teams and channels section, click the link for Use the Groups dashboard in the Office 365 admin center to manage teams.
You can control which users in your organization can create teams in Microsoft Teams. The same creation settings defined by Office 365 Groups apply to Microsoft Teams. For more information about managing Office 365 Groups, see Create an Office 365 Group in the admin center and Manage Office 365 Group Creation.
Note: You can't create teams from the Groups dashboard. Teams must be created by using the Microsoft Teams desktop client or web app.
By default, every user can create a team or group. Users can create teams by choosing Teams on the left side in the Microsoft Teams client (desktop client or web app), and then choosing Create team at the bottom of the client, below the team list.
Channels are subcategories of teams. Anyone on the team can add a channel and participate in the conversations in a channel. You might create a channel for an activity or for a department. Conversations, files, and wikis are specific to each channel, but all members of the team can see them.
Calls and meetings
Microsoft Teams includes calling and meeting capabilities. Some companies may want to turn off those features. You can choose if users can schedule private or channel meetings or use video and screen sharing during meetings. To turn on or turn off any of these capabilities, click or tap its adjacent toggle switch to Off or On and then choose Save.
As a tenant admin, you can turn on or turn off the availability of media content such as gifs, memes, and stickers.
To turn on or turn off gifs, click or tap the toggle switch next to Enable Giphy so users can add gifs to conversations to Off or On, and then choose Save.
You can apply a content rating to restrict the type of gifs that can be displayed in conversations. Gifs in Microsoft Teams are powered by Giphy, which uses a rating system for the images. You can set the rating to be one of the following:
Strict: Allows content rated "Y - Young Audiences"
Moderate: Allows content rated "PG - Parental Guidance"
Allow all content: Allows all content with no restriction
To turn on or turn off custom memes, click or tap the toggle switch next to Enable memes that users can edit and add to conversations to Off or On, and then choose Save.
To turn on or turn off stickers, click or tap the toggle switch next to Enable stickers that users can edit and add to conversations to Off or On, and then choose Save.
You can also control whether email messages can be edited or deleted. To turn on or turn off this capability, click or tap the toggle switch next to Allow owners to delete all messages, Allow users to edit their own messages, and Allow users to delete their own messages to Off or On, and then choose Save.
Office 365 Connectors
Office 365 Connectors allow your Microsoft Teams users to receive updates from popular services such as Twitter, Trello, Wunderlist, GitHub, and VSTS within the chat stream in their team.
Developers can integrate with Microsoft Teams by building custom connectors to generate rich cards within channels. See Getting started with Office 365 Connectors for Microsoft Teams (preview) and Connect apps to your groups for more information. Developers can also learn more from Office Dev Center - Microsoft Teams.
