CHG0760736 – Production – Disable Teams External Chat with Unmanaged Teams Users (Personal Teams Accounts

25/03/2022 04:53:00 PM (GMT)

Microsoft Teams external chat with unmanaged Teams users (Personal Teams accounts) is enabled by default in the tenant. This RFC aims to disable that feature so that NHSmail users can communicate to external users only on the approved B2B domains.

The policy will be disabled to restrict:

  • People in my organization can communicate with Teams users whose accounts aren’t managed by an organization
  • External users with Team accounts not managed by an organization can contact users in my organization

The default feature will be disabled for further assessment. Based on the assessment, a custom policy will be used to control, if individual users can be allowed to use this to communicate with external unmanaged Teams accounts.
