Overview
- Microsoft stopped distributing the optional KB5002907 update after Tuesday's rollout when customers and IT providers reported that the update treated some Office installs as unlicensed and, in some cases, removed the programs from disks.
- The problem mainly affected one-time‑purchase versions such as Office 2016 and Office 2019, which are already out of official support and therefore more vulnerable to repair actions.
- KB5002907 was intended as a repair action to update Microsoft 365 apps more than 90 days out of date on devices on the Current and Monthly Enterprise channels across Windows 11, Windows 10 and multiple Windows Server releases.
- Microsoft advises affected users to manually reactivate purchased Office products or to re-download and reinstall removed software and to contact support if reactivation fails, but some reports say reactivation can be blocked by account or network issues.
- Managed service providers reported that the update sometimes installed despite being labeled optional, raising concerns about update controls for mixed, legacy environments and the wider risk of repair updates interacting with end-of-life software.
