Microsoft Teams Phishing Alert Feature

In February 2025, Microsoft Teams will introduce a long-awaited feature designed to protect organizations from phishing and spam attacks — alerts for external messages that could be malicious. For cybersecurity experts and IT administrators, this update promises to be a game-changer in the fight against increasingly sophisticated cyber threats.
