Microsoft Confirms KB5002907 Update Deletes Office Licenses, Triggers Uninstalls

Microsoft has acknowledged that optional update KB5002907, intended to fix Microsoft 365 component update failures, accidentally deletes Office 2016 and 2019 licenses and in some cases uninstalls the suite entirely; the company has halted distribution and advises affected users to reactivate with original licenses or reinstall Office.
