Microsoft adds malicious link warnings to Teams chats
🔔 Microsoft Teams will display warnings on private messages that contain URLs flagged as spam, phishing, or malware for customers using Microsoft Defender for Office 365 and enterprise Teams. The feature enters public preview for desktop, Android, web, and iOS in September 2025 and is slated for general availability in November 2025. Admins can enable the preview via the Teams Admin Center messaging settings; warnings will be enabled by default at GA and can be managed through the Teams Admin Center or PowerShell.
