The change is aimed at helping security teams respond to threats that may be specific to their environment, rather than being restricted to a fixed set of blocked extensions. Admins will be able to add or remove file extensions based on what they consider dangerous for their users.

Key points:

• Admins will be able to modify the list of blocked file extensions in Teams.
• The default blocked list targets file types commonly associated with security threats.
• The feature is designed to help organizations meet their own security requirements.
• No specific CVE ID or advisory identifier is referenced in the source material.

There is no information in the source about an exact rollout timeline beyond the indication that the capability is coming soon.

Will your organization customize the blocked extension list in Teams, or do you plan to keep the default settings?
