SUMMARY:

1. You can drastically reduce bandwidth consumption when distributing new Microsoft Teams updates as part of Office 365 Pro Plus, using Delivery Optimization.
2. Delivery Optimization includes peer-to-peer update sharing at remote locations like branch offices, eliminating the need for each client to individually download Teams/Office 365 Pro Plus updates over a WAN.
3. This is possible using SCCM (now known as Endpoint Configuration Manager) if Express Updates are configured. SCCM Express Updates enable a client to download only the changes between the current month’s update and the previous month’s update.

BACKGROUND:

Windows 10 & Office 365 Pro Plus updates, upgrades, and applications can contain packages with very large files. Downloading and distributing updates can consume quite a bit of network resources on the devices receiving them. You can use Delivery Optimization to reduce bandwidth consumption by sharing the work of downloading these packages among multiple devices in your deployment. Delivery Optimization can accomplish this because it is a self-organizing distributed cache that allows clients to download those packages from alternate sources (such as other peers on the network) in addition to the traditional Internet-based servers. You can use Delivery Optimization in conjunction with Windows Update, Windows Server Update Services (WSUS), Windows Update for Business, or Microsoft Endpoint Configuration Manager (when installation of Express Updates is enabled).

(Delivery Optimization is a cloud-managed solution. Access to the Delivery Optimization cloud services is a requirement. This means that in order to use the peer-to-peer functionality of Delivery Optimization, devices must have access to the internet.)

Please note that with the new inclusion of Microsoft Teams in Office 365 Pro Plus, it’s now possible for endpoints to have the delivery of Microsoft Teams updates optimized for distribution using Endpoint Configuration Manager. (formerly known as SCCM)
