Coming soon for Microsoft Teams admin center: For the existing Meeting chat control, we will add two new options that allow admins to disable meeting chat before and after a meeting, In-meeting only for everyone and In-meeting only except anonymous users.

This message is associated with Microsoft 365 Roadmap ID 422808.

When this will happen:

How this will affect your organization:

After this rollout, admins will find the two new options in the Teams admin center > Meetings > Meeting policies > Meeting engagement > Meeting chat.

Admins can select from five Meeting chat options:

• On for everyone
• On for everyone but anonymous users
• Off
• In-meeting only for everyone (new)
• In-meeting only except anonymous users (new)

Admins can select the In-meeting only options to disable the ability of meeting participants to send messages in the meeting chat before or after the meeting, for meetings organized by specific users in their tenant. When one of the In-meeting only options is selected, participants can read past chat history, but they can only send messages in the meeting chat while the meeting is active.

The new options will be available for admins to configure. This rollout will respect the options selected by admins before the rollout. To use the new options, admins must select one of them.

What you need to do to prepare:

This rollout will happen automatically by the specified date with no admin action required before the rollout. Review your current configuration to determine the impact for your organization. You may want to notify your users about this change and update any relevant documentation.
