Microsoft is enhancing security in Teams due to rising phishing attacks in one-to-one chats from external tenants.

⭐ Key Updates:

⚠️ Trial tenants without paid licenses can no longer send chat messages.

⚠️ New brand impersonation detection will alert users if an external message appears suspicious.

⚠️ Users can preview messages, but warnings will indicate potential spam or phishing attempts.

Stay vigilant and protect your communications!
