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.
Note: To perform this procedure, use the new Office 365 admin center experience, not the old admin center. For more information, see About the Office 365 admin center.
Go to Settings > Services & add-ins.
On the Services & add-ins page, select Microsoft Teams.
On the Microsoft Teams settings page that opens, click or tap the toggle next to Turn Microsoft Teams on or off for your entire organization to On to turn on Teams for your organization, and then choose Save. If you don’t want to allow Microsoft Teams in your organization, click or tap to switch the toggle to Off.
Guest access is not enabled by default. For more details about allowing guest users from outside your organization, see Guest access in Microsoft Teams.
Note: Education admins only: Select the education license you want to configure, either Faculty and Staff or Student.
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 email@example.com.
Set-MsolUserLicense -UserPrincipalName "firstname.lastname@example.org" -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 email@example.com -RemoveLicenses "litwareinc:ENTERPRISEPACK"
For more details and examples, see Remove licenses from user accounts with office 365 PowerShell.
Tenant-wide settings for Microsoft Teams
In Tenant-wide settings, you can turn on or turn off options in General, Email integration, Apps, and Custom cloud storage.
Note: Unless otherwise noted, the default value for an option is On.
In the General section, you can choose if you want to show an organization chart in user profiles. By default, this setting is turned on. To change this setting, click or tap to switch the toggle next to Show organizational chart in personal profile to Off or On, and then choose Save.
If your Teams users are interacting with someone in your organization who doesn’t have Teams, but does have Skype for Business, your users can engage with them via Teams. Click or tap to switch the toggle next to Use Skype for Business for recipients who don’t have Microsoft Teams to Off or On, and then choose Save.
To allow T-Bot to proactively send users help content and tips and tricks, click or tap to switch the toggle next to Allow T-Bot proactive help messages to Off or On, and then choose Save.
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.
You can also block senders by specifying domain names in Restricted Senders List.
Third-party services are building rich experiences, or apps, by extending Microsoft Teams. For example, developers can implement an app with a bot and a tab, or an app with a tab and a connector, or an app with all three capabilities at once. As an admin, you can manage which third-party apps can be used in Microsoft Teams:
Choose to allow or block all third-party apps.
Individually choose which apps to allow or block.
Choose what happens as new apps get submitted into the Microsoft Teams app catalog.
When you're working with Apps settings, you can manage your tenant's app catalog all in one place.
To allow or block third-party apps, click or tap to switch the toggle next to Allow external apps in Microsoft Teams to Off or On, and then choose Save. Turning this control On allows you to select which specific apps are enabled and disabled. However, if sideloading is turned on, the granular app settings as shown below won't be available. All apps will be enabled.
To prevent or allow new external apps to be available by default, click or tap to switch the toggle next to Enable new external apps by default to Off or On, and then choose Save. This control sets the default behavior for what happens to new apps after they’re submitted to the Microsoft Teams app catalog.
Sideloading is the process of adding apps to Microsoft Teams by uploading a zip file directly to a team. It's useful because it allows users to test an app as it's being developed. Sideloading also lets you build an app for internal use only, so you can share it with your team without submitting it to the Teams app catalog. To prevent or allow sideloading of external apps, click or tap to switch the toggle next to Allow sideloading of external apps, to Off or On, and then choose Save. The default value is Off.
Apps settings and user experience
When any settings are applied, they’ll gradually roll out to your users across their devices without any explicit action by them. Users will see a message letting them know some apps may be disallowed. Results of app settings changes include the following:
Bots If a user had an existing conversation with a bot, all the contents of that conversation stay intact. The only difference is that users won’t be able to interact with the bot, so no more sending or receiving messages.
Tabs When an app is disabled, all tab instances in the UI disappear. If the app is re-enabled, all pre-existing tab instances reappear exactly as you left them.
Connectors Blocked apps with connectors won’t be able to send messages anymore. If an app is re-enabled, pre-existing configured connectors will be able to send messages again.
Custom cloud storage
Users can upload and share files from cloud storage services in Microsoft Teams channels and chats. Click or tap the toggle switch next to the cloud storage providers that your organization wants to use.
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.
Settings apply to both users in your organization and also to guest users. For more information, see Guest access in Microsoft Teams.
Note: Unless otherwise noted, the default value for an option is On.
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 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 organizations may want to turn off those features. You can choose if users can schedule private or channel meetings, have ad-hoc meetings, use video and screen sharing during meetings, or make private calls. 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 an 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"
The Moderate rating is the default value.
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. For Allow users to delete their own messages, the default value is Off.
Finally, click or tap the toggle switch next to Allow owners to chat privately to Off or On.
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.
