Faculty, staff, and active students are able to download Microsoft Office 365 ProPlus applications on up to 5 devices (PC, Mac, and/or mobile devices - Android or iOS) by following these instructions. If there is an existing copy of Office on the computer, it will remain on the computer. Office 365 ProPlus will be installed in addition to the existing Office installation.
Because of Office 365's online activation features, Office 365 ProPlus will not work on computers that are completely cut off from the Internet.
**As part of the installation process, Office 365 ProPlus communicates with the Office Licensing Service and the Activation and Validation Service to obtain and activate a product key. Each day, or each time the user logs on to their computer, the computer connects to the Activation and Validation Service to verify the license status and extend the product key. As long as the computer can connect to the Internet at least once every 30 days, Office enters reduced functionality mode until the next time a connection can be made. To get Office fully functional again, usually a user can simply connect to the Internet and let the Activation and Validation Service reactivate the installation.
