Share screen in Teams

Microsoft Teams has become an essential tool for communication and collaboration in work and educational environments. Among its many features, screen and file sharing is one of the most useful and frequently used in virtual meetings and group chats.

This article explains in detail how to get the most out of these features , whether you're using Teams on Windows , Mac , or the free version. We'll also show you how to give or take control of your screen, use the collaborative whiteboard, and adjust key settings to avoid problems when sharing content.

How to share files in Microsoft Teams

Sharing files in Teams is as simple as attaching them from your device or the cloud . You can send them directly in a chat, a team channel, or during a meeting.

These files can be stored on your computer, in OneDrive, or on any enabled channel. You can also choose whether to share the file itself or send a link to it. This facilitates collaboration without the need to forward multiple versions of the same document.

Presenting content in a meeting

To share something during a video call, the 'Share' control in the meeting toolbar is your best friend . From there, you can choose whether to share your entire screen, a specific window, or specific files like PowerPoint or Excel.

Additionally, Teams allows you to share presentations with interactive features like annotations and whiteboards, making them ideal for training sessions or demonstrations.

Presenter controls in Teams

When you are the presenter, you have access to the moderator toolbar , which allows you to control the microphone, camera, give or take back control, chat, or even annotate the shared content.

To activate this bar, simply move your cursor to the top of the shared screen. It will appear floating and allow you to make quick adjustments without interrupting the presentation.

Some key features of this bar include:

  • camera and microphone: turn them on or off instantly.
  • Give in and regain control: perfect for real-time collaboration.
  • Annotate: to highlight points or make quick drawings.
  • Shared design and audio: better focuses the content and allows the inclusion of system sound.

Using Microsoft Teams on Mac

On Mac devices, screen sharing requires additional permissions due to operating system policies . The first time you try to do this, Teams will ask you to grant access to screen recording.

If the options don't appear automatically, you can go to Apple Menu > System Settings > Privacy & Security and enable Microsoft Teams in the screen recording section. Once you've done this, you'll be able to share windows, presentations, or your entire desktop without any problems.

Content sharing options

Teams offers multiple ways to share content depending on what you want to show . These are the most common:

  • Screen: your entire screen, useful for general demonstrations.
  • Window: a specific application or document.
  • PowerPoint Live: for interactive presentations.
  • Microsoft whiteboard: a collaborative digital whiteboard accessible from multiple devices.

If you want to include your computer's sound (such as when showing a video), enable the "Include system sound" option when sharing.

Zoom and view shared content

When another participant shares content and you need to see it better, you can zoom in several ways. You have buttons in the upper corner of the screen to zoom in or out.

You can also drag the content to center it on a specific area or open it in a new window for better focus without distractions. Learn more about sharing files in Teams.

Take control of a shared presentation

During a session where someone else is sharing, you can request control . This is ideal for collaborating, editing documents live, or contributing your own data.

Simply tap "Take control" and wait for the person sharing to accept your request. Then you can control the shared screen as if it were your own.

When you're finished, select the "Release control" option to return it to the original presenter.

Use free Teams to share your screen

In the free version of Teams, you can also share your screen and files , whether with colleagues, friends, or family. Participants will be able to view, edit (if you allow it), and collaborate in real time.

From a chat, click on “More options” and select “Share screen” or choose a specific window . Other users will receive a notification to accept the shared content, and viewing will begin.

End screen sharing

At any time you can stop sharing your screen simply by pressing the "Stop sharing" option from the meeting controls or from the top bar if you are presenting.

You can also end the session by leaving the meeting or closing the shared content in a separate window, if you had opened it that way.

Enable the Whiteboard feature in Teams

The Whiteboard collaborative whiteboard is available on most devices and platforms , including the web version, Windows, iOS , Android , and Surface Hub.

To activate it, go to the Teams admin center , search for Whiteboard, go to settings, and enable it for the entire team. Once activated, clicking "Share" during a call will allow you to access Microsoft Whiteboard, select an existing one, or create a new one for the meeting.
