Office Pro Plus, the cloud-connected version of Office, delivers the most productive and most secure Office experience-with the lowest total cost of ownership for deployment and management. However, for customers who aren't ready for the cloud, Office 2019 provides new features and updates to the on-premises apps for both users and IT professionals. Like Windows Long Term Servicing Channel (LTSC) releases, Office 2019 provides a set of valuable enhancements for customers who can't be cloud-connected or receive regular updates.
