Microsoft Teams: Chat with anyone who has an email address

🚨 The Signal: Microsoft has cancelled the feature allowing Teams users to chat with external email addresses. This prevents a potential increase in unmanaged external communication channels and associated data leakage risks.

• Security Teams: Reduced risk of data exfiltration via unmanaged external chat.
• Compliance Teams: Avoids new complexities in data retention and e-discovery for external communications.
• Identity Teams: No new guest identity management challenges from email-only invitations.
