Upgrading Office 2019 to Microsoft 365 (Windows)


Learn how to upgrade your Windows computer from Office 2019 to Microsoft 365 Apps for Enterprise.

What is changing?

Mainstream support for Microsoft Office 2019 ends on October 10th, 2023. To ensure smooth operations all managed computers at the University of Oregon will automatically be upgraded to the newer subscription-based version of Microsoft Office, Microsoft 365 Apps for Enterprise.

Most users on managed computers are already using Microsoft 365 (M365), but users that remain on Office 2019 will be upgraded soon and will gain access to improved features that are only available in M365.

What happens if the software is not upgraded?

  • Office 2019 will no longer be officially supported by Microsoft. As a result of this future bugs or security vulnerabilities may not be patched as quickly, or at all.
  • Connectivity to Microsoft 365 online services, such as email may be interrupted.
  • The feature disparity between Office 2019 and M365 will continue to grow and current workflows may cease to work in the future.
