Short answer: In your Teams meeting, click Share content, then under Window choose the specific app window you want. Only that window is shared, and everything else on your screen stays private. The full steps are below, along with the one big limitation (Teams only lets you share one window at a time) and how to get around it.

Step by step: share one window in Teams on Mac

1. Grant Teams Screen Recording permission. Open System Settings → Privacy & Security → Screen Recording and turn on Microsoft Teams. macOS requires this before any app can share your screen. Quit and reopen Teams if it asks.
2. Start or join your meeting so the meeting toolbar is visible.
3. Click “Share content.” It’s the icon that looks like a rectangle with an arrow, in the meeting controls.
4. Pick a Window, not Screen. In the share tray you’ll see Screen (your whole display) and Window (individual apps). Under Window, click the exact window you want to present.
5. You’re sharing. The chosen window gets a red border, and that’s all anyone sees. Click Stop sharing when you’re done.

Why can you only share one window at a time?

This is the part that trips people up. Microsoft Teams (like Zoom and Google Meet) only gives you two real options: share one window, or share your entire screen. There’s no built-in way to share two specific windows at once.

So the moment you need to show a second window, you’re stuck choosing between two bad workarounds:

• Share your whole screen instead. Now everything is exposed, notifications, other apps, that other client’s work, and on a large monitor it all shrinks down so small that people ask you to “zoom in.”
• Stop sharing and re-share the other window. You interrupt the meeting, hunt through the share tray again, and make everyone wait, every single time you switch.

In a demo, a pairing session, or a client call where you’re bouncing between an editor, a browser, and some slides, you end up fighting the share menu instead of presenting.

How to share multiple windows and switch between them live

This is exactly the gap PrivacyStage was built to close. It’s a small macOS app that gives you dynamic screen sharing on top of Teams (or Meet, or Zoom, or anything that shares a screen):

• Tag the windows you want. Pick several app windows and share them together, not one at a time.
• Switch live, no re-sharing. The shared view follows whichever tagged window you click into, so you just work and it keeps up.
• Add or remove windows on the fly, mid-call, without stopping.
• Readable, not tiny. Your windows are sent at a share-friendly size, so a big monitor doesn’t come out shrunk.
• Everything else stays private. Untagged windows, notifications, and other apps never appear.

You share it in Teams like any normal screen (it shows up as a display you can pick), and it runs entirely on your Mac. If you specifically want to show several windows at once, see our guide on sharing multiple windows on Zoom & Teams.
