Microsoft Office 2021 Perpetual License Disabled After Software Update

A Mac user reports that a Microsoft Office Home & Business 2021 perpetual license stopped working after Office updated. On October 24, 2026, Excel version 16.114.1 would not save spreadsheets and instead prompted the user to activate a subscription, although the Microsoft account still showed the valid purchase. Microsoft’s installation page supplied the same incompatible version. The user removed the Office apps and installed version 16.113.4, downloaded from an earlier installer, after which Excel recognized the license and saving worked again. The user argues that automatically updating a paid, perpetual product into a state that blocks essential functions is unacceptable, and asks Microsoft to prevent incompatible updates and offer a clear recovery path.

In the discussion, a volunteer moderator confirms that the apps must be removed before reinstalling a compatible build and suggests version 16.114, but not 16.114.1. The moderator also advises turning off automatic updates to prevent another incompatible upgrade and directs complaints to Microsoft’s Feedback portal. Microsoft’s AI-generated guidance adds that perpetual licenses may fail with Mac App Store versions of Office or mismatched licensing and update states; it recommends installing the Microsoft-distributed build and, if needed, removing saved Office license files before reactivation. The exchange offers a practical workaround but does not establish why version 16.114.1 rejected this user’s license or show that Microsoft has explained the incident.
