Product

Device & OS
not provided
Scenario
Hosting a Microsoft Teams meeting with external participants who do not have Microsoft accounts.

Before you start

Verify that you have Microsoft 365 or Microsoft Teams administrator privileges, as enabling external access to Whiteboard requires modifying organizational policies.

Solution 1Recommended

Configure Microsoft Teams and Microsoft 365 Admin Settings

This solution explains how a Microsoft 365 administrator can adjust organizational sharing settings to permit external users to collaborate on Whiteboard during a Teams meeting.

By default, external participants or anonymous users without Microsoft accounts may be blocked from interacting with apps like Whiteboard in Teams meetings. To allow them to view and collaborate, your organization's administrator must enable specific app interaction and external sharing policies.

1
Enable anonymous interaction in Teams Admin Center

Log in to the Microsoft Teams Admin Center. Navigate to 'Meetings', then select 'Meeting settings'. Find the setting for 'Anonymous users can interact with apps in meetings' and toggle it on.

2
Enable Whiteboard for external sharing

Open the Microsoft 365 Admin Center. Go to 'Settings', select 'Org settings', and then click on 'Whiteboard'. Ensure that the option to share whiteboards with external users is checked and saved.

3
Launch Whiteboard in the meeting

Start your Teams meeting, click the 'Share' button, and select 'Microsoft Whiteboard'. External users will now be able to collaborate on the canvas temporarily for the duration of the meeting.

Configure Microsoft Teams and Microsoft 365 Admin Settings
Temporary Access: External users' access to the Whiteboard is typically temporary. Once the Teams meeting concludes, they may no longer be able to view or edit the Whiteboard contents.

Frequently Asked Questions

Can external users access the Microsoft Whiteboard after the Teams meeting ends?

Generally, no. Access for external or anonymous users without Microsoft accounts is temporary and typically expires once the Teams meeting has ended.

Why are external users unable to see the Whiteboard when I share it in Teams?

This usually happens because the organization's administrator has not enabled the 'Anonymous users can interact with apps in meetings' setting in the Teams Admin Center, or external sharing is disabled in the Microsoft 365 Whiteboard settings.

Do external participants need to download the Microsoft Whiteboard app to collaborate?

No. When shared during a Teams meeting, external participants can view and draw on the Whiteboard directly within the Teams meeting window or via their web browser.
