Effective November 29, 2018, you'll no longer be able to use the Microsoft Teams for Windows 10 S (Preview) app, available from the Microsoft Store. Instead, you can now download and install the Teams desktop client on devices running Windows 10 S mode. To download the desktop client, go to https://teams.microsoft.com/downloads. MSI builds of the Teams desktop client are not yet available for devices running Windows 10 S mode.

For more information about Windows 10 S mode, see Introducing Windows 10 in S mode.

Desktop client

Tip

Watch the following session to learn about the benefits of the Windows Desktop Client, how to plan for it, and how to deploy it: Teams Windows Desktop Client

The Microsoft Teams desktop client is a standalone application and is also available in Microsoft 365 Apps for enterprise. Teams is available for 32-bit and 64-bit versions of Windows (8.1 or later), ARM64 for Windows 10 on ARM, and Windows Server (2012 R2 or later), as well as for macOS and Linux (in .deb and .rpm formats). On Windows, Teams requires .NET Framework 4.5 or later; the Teams installer will offer to install it for you if you don't have it. On Linux, package managers such as apt and yum will try to install any requirements for you. However, if they don't then you will need to install any reported requirements before installing Teams on Linux.

The desktop clients provide real-time communications support (audio, video, and content sharing) for team meetings, group calling, and private one-on-one calls.

Desktop clients can be downloaded and installed by end users directly from https://teams.microsoft.com/downloads if they have the appropriate local permissions (admin rights are not required to install the Teams client on a PC but are required on a Mac).

Note

For more details about installing Teams on a Chromebook, please see How to install and run Microsoft Office on a Chromebook.

IT admins can choose their preferred method to distribute the installation files to computers in their organization. Some examples include Microsoft Endpoint Configuration Manager (Windows) or Jamf Pro (macOS). To get the MSI package for Windows distribution, see Install Microsoft Teams using MSI.

Note

Distribution of the client via these mechanisms is only for the initial installation of Microsoft Team clients and not for future updates.

Windows

The Microsoft Teams installation for Windows provides downloadable installers in 32-bit and 64-bit architecture.

Note

The architecture (32-bit vs. 64-bit) of Microsoft Teams is agnostic to the architecture of Windows and Office that is installed.

The Windows client is deployed to the AppData folder located in the user’s profile. Deploying to the user’s local profile allows the client to be installed without requiring elevated rights. The Windows client leverages the following locations:

• %LocalAppData%MicrosoftTeams

• %LocalAppData%MicrosoftTeamsMeetingAddin

• %AppData%MicrosoftTeams

• %LocalAppData%SquirrelTemp

When users initiate a call using the Microsoft Teams client for the first time, they might notice a warning with the Windows firewall settings that asks for users to allow communication. Users might be instructed to ignore this message because the call will work, even when the warning is dismissed.

Note

Windows Firewall configuration will be altered even when the prompt is dismissed by selecting “Cancel”. Two inbound rules for teams.exe will be created with Allow action for both TCP and UDP protocols.

If you want to prevent Teams from prompting users to create firewall rules when the users make their first call from Teams, use the Sample PowerShell script - inbound firewall rule below.

Mac

Mac users can install Teams by using a PKG installation file for macOS computers. Administrative access is required to install the Mac client. The macOS client is installed to the /Applications folder.

Install Teams by using the PKG file

1. From the Teams download page, under Mac, click Download.
2. Double click the PKG file.
3. Follow the installation wizard to complete the installation.
4. Teams will be installed to /Applications folder. It is a machine-wide installation.

Note

During the installation, the PKG will prompt for admin credentials. The user needs to enter the admin credentials, regardless of whether or not the user is an admin.

If a user currently has a DMG installation of Teams and wants to replace it with the PKG installation, the user should:

1. Exit the Teams app.
2. Uninstall the Teams app.
3. Install the PKG file.

IT admins can use managed deployment of Teams to distribute the installation files to all Macs in their organization, such as Jamf Pro.

Note

If you experience issues installing the PKG, let us know. In the Feedback section at the end of this article, click Product feedback.

Linux

Users will be able to install native Linux packages in .deb and .rpm formats. Installing the DEB or RPM package will automatically install the package repository.

• DEB https://packages.microsoft.com/repos/ms-teams stable main
• RPM https://packages.microsoft.com/yumrepos/ms-teams

The signing key to enable auto-updating using the system's package manager is installed automatically. However, it can also be found at: https://packages.microsoft.com/keys/microsoft.asc. Microsoft Teams ships monthly and if the repository was installed correctly, then your system package manager should handle auto-updating in the same way as other packages on the system.

Note

If you find a bug, submit it using Report a Problem from within the client. For known issues, see Support Teams in your organization.For Teams for Linux support you can use the Linux forum support channel on Microsoft Q&A. Be sure to use the teams-linux tag when posting questions.

Web client

The web client (https://teams.microsoft.com) is a full, functional client that can be used from a variety of browsers. The web client supports Calling and Meetings by using webRTC, so there is no plug-in or download required to run Teams in a web browser. The browser must be configured to allow third-party cookies.

Teams fully supports the following Internet browsers, with noted exceptions for calling and meetings. This table applies to operating systems running on desktop computers.

¹ To give and take control of shared content during sharing, both parties must be using the Teams desktop client. Control isn't supported when either party is running Teams in a browser. This is due to a technical limitation that we're planning to fix.

² Blur my background isn't available when you run Teams in a browser. This feature is only available in the Teams desktop client.

³ Teams meetings on browsers are limited to a single incoming video feed of active speaker.

Microsoft Teams Firefox

⁴ Edge RS2 or later doesn't support sending real-time audio and video traffic through HTTP proxies.

Note

As long as an operating system can run the supported browser, Teams is supported on desktop computers. For example, running Firefox on the Linux operating system is an option for using Teams.

For mobile operating systems, we recommend that you run the Teams app, available from the Android and iOS stores. Running Teams in a mobile operating system is supported, but many features are unavailable.

The web client performs browser version detection upon connecting to https://teams.microsoft.com. If an unsupported browser version is detected, it will block access to the web interface and recommend that the user download the desktop client or mobile app.

Mobile clients

The Microsoft Teams mobile apps are available for Android and iOS, and are geared for on-the-go users participating in chat-based conversations and allow peer-to-peer audio calls. For mobile apps, go to the relevant mobile stores Google Play and the Apple App Store. The Windows Phone App was retired July 20, 2018 and may no longer work.

In China, here's how to get Teams for Android.

Supported mobile platforms for Microsoft Teams mobile apps are the following:

• Android: Support is limited to the last four major versions of Android. When a new major version of Android is released, the new version and the previous three versions are officially supported.

• iOS: Support is limited to the two most recent major versions of iOS. When a new major version of iOS is released, the new version of iOS and the previous version are officially supported.

Microsoft

Note

The mobile version must be available to the public in order for Teams to work as expected.

Mobile apps are distributed and updated through the respective mobile platform’s app store only. Distribution of the mobile apps via MDM or side-loading is not supported by Microsoft. Once the mobile app has been installed on a supported mobile platform, the Teams Mobile App itself will be supported provided the version is within three months of the current release.

Client update management

Clients are currently updated automatically by the Microsoft Teams service with no IT administrator intervention required. If an update is available, the client will automatically download the update and when the app has idled for a period of time, the update process will begin.

Client-side configurations

Currently, there are no supported options available to configure the client either through the tenant admin, PowerShell, Group Policy Objects or the registry.

Notification settings

There are currently no options available for IT administrators to configure client-side notification settings. All notification options are set by the user. The figure below outlines the default client settings.

Sample PowerShell script - inbound firewall rule

This sample script, which needs to run on client computers in the context of an elevated administrator account, will create a new inbound firewall rule for each user folder found in c:users. When Teams finds this rule, it will prevent the Teams application from prompting users to create firewall rules when the users make their first call from Teams.

Microsoft has already announced a long time ago that it wanted to bring a walkie talkie feature to Microsoft Teams, and now it seems like it’s finally happening.

As discovered recently, Microsoft is now working on updating Microsoft Teams for iOS with walkie talkie support, with the feature to go live as soon as June.

As you could easily figure out, this new feature has a very simple purpose: to allow Microsoft Teams users to chat with each other instantly just like they’d do it with a walkie talkie.

The feature will work on both iPhones and iPads, and Microsoft says it’ll overall reduce the costs for IT because employees can simply give up on traditional walkie talkies.

Update going live in June

Originally announced in January 2020, the update was released in private preview builds last year, according to Microsoft itself.

“This new push-to-talk experience enables clear, instant, and secure voice communication over the cloud, turning employee- or company-owned smartphones and tablets into a walkie-talkie. The functionality, built natively into Teams, reduces the number of devices employees must carry, and lowers costs for IT,” Microsoft said.

Microsoft Teams On Firefox

“Unlike analog devices with unsecure networks, customers no longer have to worry about crosstalk or eavesdropping from outsiders. And since Walkie Talkie works over Wi-Fi or cellular data, it can be used across geographic locations. The capability will be available in the Teams mobile app and integrate with the newly unveiled Samsung Galaxy XCover Pro, a device built for workers on the front lines of any industry. Walkie Talkie will be available in private preview in Teams in the first half of this year.”

The update aimed at iOS devices is therefore expected in just a few months, so expect more information to be shared in the coming weeks.
