Description
Having access to updates, add-ins, and patches on the Office Online website can help users ensure computers are up to date and equipped with the latest security patches. However, to ensure updates are tested and applied in a consistent manner, many organizations prefer to roll out updates using a centralized mechanism such as Microsoft Systems Center or Windows Server Update Services. By default, users are allowed to download updates, add-ins, and patches from the Office Online Web site to keep their Office applications running smoothly and securely. If an organization has policies that govern the use of external resources such as Office Online, allowing users to download updates might cause them to violate these policies.
