Summary:
Microsoft Teams will use peer-to-peer update distribution via Delivery Optimization starting December 2025, enabling devices on the same network to share update files. This reduces CDN bandwidth use, speeds updates, and saves up to 30% bandwidth. No admin action is needed, but network policies should allow Delivery Optimization.
Details:
We're improving the way Microsoft Teams updates are delivered to make collaboration smoother and reduce network load. Teams will now use peer-to-peer (P2P) update distribution through Delivery Optimization (DO), enabling devices on the same network to share update files. This reduces reliance on CDN bandwidth and speeds up update completion.
When this will happen
General Availability (Worldwide): Rollout begins in early December 2025 and is expected to complete by late December 2025.

summary for non-techies**
Microsoft Teams will implement a peer-to-peer (P2P) update system starting December 2025, allowing devices on the same network to share update files, reducing central server load and saving up to 30% of internet bandwidth, with no administrative action required if network settings permit file sharing.
Direct effects for Operations**
Bandwidth Utilization
Increased reliance on local network bandwidth for updates may lead to congestion, affecting other applications and services if not properly managed.
