Cryptographic Expiration: Microsoft Office 2019 for Mac Faces Imminent Functionality Restrictions

Consumers of Microsoft Office 2019 on macOS/iOS/iPadOS will face a reduced-functionality (read-only) mode beginning July 13, 2026, due to expiration of underlying digital licensing certificates; Microsoft will only distribute the necessary certificate updates via modern update channels, and Office 2019 for Mac (unsupported since October 2023) will not receive a remediation, prompting recommendations to migrate to Microsoft 365, Office 2024, or the free web apps and causing consumer backlash over revised support language.
