summary for non-techies**

Starting in mid-March 2025, Microsoft Teams will introduce a feature where anonymous users will see their entered name as a watermark on meeting content, ensuring transparency while allowing full participation, with administrators having the option to restrict their access to audio only using a PowerShell script.

Direct effects for Operations**

Increased Risk of Data Leakage
With anonymous users having access to all meeting content, there is a heightened risk of sensitive information being leaked if proper controls are not in place.
