   Microsoft Teams to Roll Out Malicious Link Warnings in Private Chats

   Microsoft Teams is introducing a new security feature to alert users about malicious links in private chats. This feature will flag URLs identified as spam, phishing, or malware, enhancing protection for enterprise customers using Microsoft Defender for Office 365 (MDO) and Microsoft Teams. The public preview will start in September 2025, with general availability in November 2025. Warnings will be displayed directly on messages containing flagged URLs, both internal and external. The feature will be enabled by default after general availability, with management options available through the Teams Admin Center or PowerShell. Administrators can opt in to the public preview and the feature will be active across the entire tenant if enabled by at least one tenant.
