By December 2026, support for Microsoft Store versions of Office applications will cease, and they will no longer receive security updates. New feature updates for Microsoft 365 Apps installed via the Microsoft Store stopped in October 2025. Users are encouraged to transition to Click-to-Run versions to maintain access to updates and security features. Click-to-Run allows for immediate application usability while downloading in the background and updates automatically. The Office Deployment Tool (ODT) can assist users in transitioning to Click-to-Run versions.
