Delivery Optimization uses locally cached updates to deliver contact via peers. The more content available in the cache, the more likely that peering can be used. In cases where devices have enough local storage and you'd like to cache more content. Likewise, if you have limited storage and would prefer to cache less, use the following settings to adjust the Delivery Optimization cache to suit your scenario:
- [Max Cache Size](#max-cache-size) and [Absolute Max Cache Size](#absolute-max-cache-size) control the amount of space the Delivery Optimization cache can use.
- [Max Cache Age](#max-cache-age) controls the retention period for each update in the cache.
- The system drive is the default location for the Delivery Optimization cache. [Modify Cache Drive](#modify-cache-drive) allows administrators to change that location.
- [DOMaxCacheSize](#max-cache-size) and [DOAbsoluteMaxCacheSize](#absolute-max-cache-size) control the amount of space the Delivery Optimization cache can use.

All cached files have to be above a set minimum size. This size is automatically set by the Delivery Optimization cloud services, but when local storage is sufficient and the network isn't strained or congested, administrators might choose to change it to obtain increased performance. You can set the minimum size of files to cache by adjusting [Minimum Peer Caching Content File Size](#minimum-peer-caching-content-file-size).

#### Policies to prioritize the use of peer-to-peer and cache server sources
When Delivery Optimization client is configured to use peers and Microsoft Connected Cache (MCC), to achieve the best possible content delivery experience, the client connects to both MCC and peers in parallel. If the desired content can't be obtained from MCC or peers, Delivery Optimization will automatically fallback to the HTTP source to get the requested content. There are four settings that allow you to prioritize peer-to-peer or MCC sources by delaying the immediate fallback to HTTP source, which is the default behavior.

When set, the Group ID will be assigned automatically from the selected source. This policy is ignored if the GroupID policy is also set. The default behavior, when the GroupID or GroupIDSource policies aren't set, is to determine the Group ID using AD Site (1), Authenticated domain SID (2) or Microsoft Entra tenant ID (5), in that order. If GroupIDSource is set to either DHCP Option ID (3) or DNS Suffix (4) and those methods fail, the default behavior is used instead. The option set in this policy only applies to Group (2) download mode. If Group (2) isn't set as Download mode, this policy will be ignored.

### Max Cache Age
### Max cache age
MDM Setting: **DOMaxCacheAge**
In environments configured for Delivery Optimization, you might want to set an expiration on cached updates and Windows application installation files. If so, this setting defines the maximum number of seconds each file can be held in the Delivery Optimization cache on each Windows 10 client device. Alternatively, organizations might choose to set this value to "0" which means "unlimited" to avoid peers redownloading content. When "Unlimited" value is set, Delivery Optimization holds the files in the cache longer and cleans up the cache as needed (for example when the cache size exceeded the maximum space allowed). **The default value is 259,200 seconds (three days)**.
### Max Cache Size
### Max cache size
MDM Setting: **DOMaxCacheSize**
This setting limits the maximum amount of space the Delivery Optimization cache can use as a percentage of the available drive space, from 1 to 100. For example, if you set this value to 10 on a Windows client device that has 100 GB of available drive space, then Delivery Optimization uses up to 10 GB of that space. Delivery Optimization constantly assesses the available drive space and automatically clear the cache to keep the maximum cache size under the set percentage. **The default value is 20%**.
### Absolute Max Cache Size
### Absolute max cache size
MDM Setting: **DOAbsoluteMaxCacheSize**
This setting specifies the maximum number of gigabytes the Delivery Optimization cache can use. This is different from the [**Max Cache Size**](#max-cache-size) setting, which is a percentage of available disk space. Also, if you configure this policy, it overrides the [**Max Cache Size**](#max-cache-size) setting. **The default value is 10 GB**.
