not all users seeing my whiteboard

Dear @Thomas Rouge,

Thank you for reaching out to the Microsoft 365 Q&A forum community support team. I understand how vital it is for your math tutoring sessions that every student can see your work. To ensure all your students can access the Whiteboard, please follow these specific technical steps: 

Step 1: Check How You Schedule the Meeting 

The way a meeting is created often determines who can see the Whiteboard.  

• If you schedule a meeting within a specific Teams "Channel," external or anonymous users will be blocked from seeing the Whiteboard. 
• Instead, schedule a regular calendar meeting (via the Teams Calendar tab) and send the link to your students. This approach is much more reliable for external participants. 

Step 2: Update Access Policy (For IT Admins) 

Since you mentioned being part of a grant program, you may need to ask your college's IT department to enable access for anonymous users via PowerShell. They should run the following command:  

Set-CsTeamsMeetingPolicy –Identity Global –AllowWhiteboards $true 

 Note: Once this is changed, it can take about 60 minutes to take effect. 

Here's an example to test:

For more details, please refer to this Set-CsTeamsMeetingPolicy (MicrosoftTeams) | Microsoft Learn 

Step 3: Encourage Students to Sign In 

The Whiteboard works best when students are recognized as part of your school's network. 

• Sign-in: Encourage students to sign in with their school-provided Microsoft account before clicking the join link. 
• Guest Status: If they join as an authenticated guest rather than an anonymous user, they will have much better visibility of your shared content. 

Step 4: Alternative Sharing Methods 

If students still cannot see the board natively, try these quick workarounds during your session: 

• Share the Link: Inside the Whiteboard, click the "..." in the upper-right corner, select Copy link, and paste it into the meeting chat. Students with a valid login can then open it directly in their web browser. 

• Desktop Sharing: As a last resort, click the Share content icon in Teams and choose to share your Screen instead of the Whiteboard app. This ensures that anyone who can see your video feed can see your math problems. 

For more technical details, you can refer to the official Manage sharing for Microsoft Whiteboard - Microsoft Whiteboard | Microsoft Learn 

I hope this helps you get back to focusing on your students. Thank you for your patience and your understanding. If you have any questions, please feel free to reach out. I'm looking forward for your reply.

In Teams meetings, everyone can only see and collaborate on the whiteboard if:

1. They are in the same organization/tenant as the meeting organizer.
2. They have been given access to that specific whiteboard.

Some of the students not seeing the whiteboard is usually caused by one of these:

• They are joining with a personal account or a different school account than the one your college provided.
• They are external/guest users from outside your organization (for example, different college, personal email). Current Whiteboard collaboration is limited to people in the same organization.

To improve this:

1. Ask students to:
   • Sign out of any personal Microsoft accounts in the browser.
   • Join the Teams meeting using their official college account.
2. Start and share the whiteboard from within the Teams meeting:
   • In the meeting, share the Whiteboard so it becomes the meeting’s dedicated board. Each Teams meeting has its own whiteboard that participants can use together.
3. If using the standalone Whiteboard app:
   • Open the board.
   • Select Share in the upper right.
   • In Send link, enter each student’s college email address and share.
   • If needed, adjust permissions (for example, Can edit vs Can view) using the Pen icon next to their name.
4. Keep in mind:
   • Collaboration is currently limited to people in the same organization. Guests outside your organization cannot collaborate on the same whiteboard yet.

If some students are still unable to see the whiteboard after using the correct college account, contact the school’s IT admin so they can verify Teams/Whiteboard settings for student accounts.
