 ## How Microsoft uses Delivery Optimization
 
-At Microsoft, to help ensure that ongoing deployments weren't affecting our network and taking away bandwidth for other services, Microsoft IT used a couple of different bandwidth management strategies. Delivery Optimization, peer-to-peer caching enabled through Group Policy, was piloted and then deployed to all managed devices using Group Policy. Based on recommendations from the Delivery Optimization team, we used the "group" configuration to limit sharing of content to only the devices that are members of the same Active Directory domain. The content is cached for 24 hours. More than 76 percent of content came from peer devices versus the Internet.
