How to Enable Camera and Screen Sharing for Teams Webinar Guests
Question details
A guest presenter in a Microsoft Teams webinar cannot share their screen or turn on their camera, even though their audio is working normally.
- Product
- Microsoft Teams
- Device & OS
- Mac
- Scenario
- Hosting a Teams webinar where external guest users are invited to present slides or share their video feed.
- Observed behavior
- The guest receives a notification stating that video sharing is disabled, and the screen sharing icon is greyed out or unresponsive.
Ensure you have access to the Microsoft Teams Admin Center if organization-wide policy changes are required, and verify that your Teams application is up to date.
Assign the Presenter Role and Rejoin
Guest users are often restricted from sharing by default. Upgrading their role to Presenter directly in the meeting usually resolves sharing limitations.
In many Microsoft Teams webinars, external users join as 'Attendees' even if they were invited to speak. Attendees are blocked from sharing their screen or turning on their camera to prevent disruptions. The meeting organizer must manually elevate the guest's status.
While in the active Teams webinar, click on the 'People' or 'Participants' icon located in the top meeting controls bar.
Find the guest user's name in the list, click the three-dot menu (More options) next to their name, and select 'Make a presenter' from the dropdown menu.
If the screen sharing or camera icons remain disabled after the role change, instruct the guest to leave the webinar and rejoin immediately. This forces the Teams client to refresh their permissions.
Enable Guest IP Video in Teams Admin Center
If the issue persists across different meetings for all guests, your organization's global guest access policies may be blocking IP video.
Check macOS System Permissions
Mac users must grant explicit system-level permissions for Teams to capture the screen and access the camera.
Enhance Your Webinar Presentations with WPS Office
While troubleshooting Microsoft Teams permissions, consider optimizing your presentation creation workflow. WPS Office is a free, lightweight, and highly compatible alternative to Microsoft Office, ensuring your presentation slides load quickly and display perfectly when sharing your screen in any webinar.
- 1. Download the software: Visit the WPS Office website and download the free installation package for your operating system.
- 2. Install and launch: Run the installer and launch the application. You can immediately open any existing Microsoft Office files without losing formatting.
- 3. Present seamlessly: Open your slideshow in WPS Presentation and utilize the clean interface to share your screen smoothly during your next Teams webinar.
Frequently Asked Questions
Why is the screen share icon greyed out for my webinar guest?
The screen share icon is typically greyed out because the guest user joined the webinar as an 'Attendee'. Attendees are restricted from sharing their screen. The meeting organizer must change their role to 'Presenter' for the icon to become active.
How long does it take for Teams Admin Center policy changes to apply?
When an administrator enables 'Allow IP Video' or modifies guest meeting policies in the Teams Admin Center, the changes can take up to 24 hours to fully propagate across the Microsoft network and apply to the users.
Do Mac users need special permissions to share their screen in Teams?
Yes. Due to macOS security features, users must explicitly grant Microsoft Teams permission to record the screen and access the camera. This is done by navigating to Apple Menu > System Settings > Privacy & Security, and enabling the toggles for Teams under 'Screen Recording' and 'Camera'.
Can I set someone as a presenter before the webinar starts?
Yes, if the guest is part of your organization or has a recognized Microsoft account, you can go to the meeting options before the webinar begins and specify them under the 'Who can present?' setting.
