NOTE  To avoid potential bandwidth congestion from a large number of PCs downloading and installing updates, we recommend that you download the necessary updates and deploy them to each of your organization's PCs prior to deploying the Office 365 desktop setup. You can deploy the updates via a package deployment tool such as Microsoft System Center Configuration Manager or a third-party application. After the updates are deployed and installed, then run Office 365 desktop setup on each PC to configure the desktop applications to work with Office 365.
