Microsoft will roll out an Efficiency Mode for Microsoft Teams in May 2026 that optimizes performance on CPU- and memory-constrained Windows and Mac devices by dynamically adjusting video resolution and app behavior. The update is enabled by default on eligible devices and is accompanied by new messaging security tools for reporting suspicious external users and a Security Detection Report for admins. #MicrosoftTeams #EfficiencyMode
