Can’t share your screen from Microsoft Edge

When the share button does nothing in Edge, the usual causes are a work rule that switches screen sharing off, or — on a Mac — macOS never having given Edge permission to record the screen.

What you are seeing

In a browser meeting in Microsoft Edge the share or present button fails, shows an error, or shares a black rectangle that nobody can read.

The likely causes, most common first

Work down the list; most people find theirs in the first two.

1. Screen sharing is switched off by your organisation

  1. Companies can turn screen sharing off in Edge for every website. When they do, the share button in any browser meeting simply fails, however you click it.
  2. There is nothing to change on your side. Use the meeting’s desktop app if you have one, or ask IT to allow the meeting site.

Microsoft: “For example, if you're using a web-based online meeting, video or screen sharing won't work.” — learn.microsoft.com/en-us/deployedge/microsoft-edge-browser-policies/screencaptureallowed

2. Only certain sites are allowed to share

  1. The same rule can carry exceptions, so sharing works on one meeting site and fails on another. If sharing fails on only one site, ask IT whether that site is missing from the allowed list.

Microsoft: “If you disable this policy, calls to screen-share APIs fail.” — learn.microsoft.com/en-us/deployedge/microsoft-edge-browser-policies/screencaptureallowed

3. macOS has not let Edge record the screen

  1. On a Mac, open System Settings → Privacy & Security → Screen & System Audio Recording, and switch on Microsoft Edge. If it is missing, add it with the plus button. Restart Edge when asked.

Apple: “You can decide which apps and websites are allowed to record your screen and audio.” — support.apple.com/guide/mac-help/control-access-screen-system-audio-recording-mchld6aa7d23/mac

4. Edge has the sound but not the screen

  1. macOS keeps screen and sound apart. If people hear your video but see black, Edge has permission for audio only; give it the screen as well.

Apple: “You can allow apps to record both your screen and audio, or just your audio.” — support.apple.com/guide/mac-help/control-access-screen-system-audio-recording-mchld6aa7d23/mac

Other Microsoft Edge problems

Microphone not workingIn Edge, the microphone has to be allowed in three places — for the meeting site, for Edge on your computer, and sometimes by whoever manages a work laptop.Camera not workingA black picture in an Edge call usually comes from one switch in Edge’s settings, a refusal you gave the site earlier, Windows privacy settings, or a rule set by your employer.Transcript missingA Google Meet transcript is saved to the organiser’s Drive, only starts from a computer or an Android phone, and waits for the host to join on the web.Recording missingGoogle Meet saves recordings to the organiser’s Drive, only records from a computer or an Android phone, and stops by itself after eight hours.Notes or summary missingGoogle’s automatic notes need an eligible plan, a meeting of about fifteen minutes or more in one supported language, and somebody from the host’s organisation to start them.Breakout rooms missingBreakout rooms in Google Meet need an eligible Workspace edition and a host on a computer, and Google never records what happens in them.
