Teams: Updated developer tools to share content from Teams apps to chats, channels, and meetings

Updated October 10, 2024: We have updated the rollout timeline below. Thank you for your patience.

Today, users can share content to a Microsoft Teams meeting directly from a standalone webapp (in the browser) if developers have embedded a Share-in-Meeting control in their webapps. Today, this control allows users to share content only to an ongoing Teams meeting (or a new ad-hoc meeting) on the same device. In this rollout, we will retain the control's existing capabilities, and we will enhance the control to enable users to share content to a meeting scheduled for the future. We will combine the Share-in-Meeting controls with the existing Share to Teams dialog box, so users can use one dialog box to share from a Teams app to Teams chats, channels, or meetings. We are also introducing the ability for users to choose Present Now from the dialog to present content in a Teams meeting. Developers can choose to opt into the features in this rollout. This rollout applies to Teams for Windows, the web, and Mac.

This message is associated with Microsoft 365 Roadmap ID 394670.

When this will happen:

Public Developer Preview: We will begin rolling out early June 2024 and expect to complete by mid-June 2024.

Targeted Release: We will begin rolling out early September 2024 (previously early August) and expect to complete by mid-October 2024 (previously mid-September).

General Availability (Worldwide, GCC): We will begin rolling out mid-September 2024 (previously mid-August) and expect to complete by late October 2024 (previously late September).

How this will affect your organization:

Additional enhancements for developers in this this rollout:

• When a meeting begins, the app side panel is opened automatically for the user who shared the content to the meeting.
• Exposes shared content information for the app to get the list of content shared, display the content, and have it readily available in the side panel.
• Notifies the meeting participants through an experience in the meeting chat that a user has shared content in the meeting.

App developers can embed the Share to Teams control on their external webapp:

Using the Share to Teams control, users can select a chat, channel, or meeting to share their content to. Users can also choose to present the content onto in a Teams meeting with the Present Now feature.

What you need to do to prepare:

This rollout will happen by the specified date with no admin action required before the rollout. Please notify your app developers about this change and update any relevant documentation as appropriate.
