Microsoft Office 2019 and 2021 for Mac may enter view-only mode in 2026 after license certificate expiry

Microsoft Office 2019 and 2021 for Mac are reportedly set to lose editing and saving functionality on July 13, 2026, when a license-validation certificate expires. The change would place perpetually licensed apps into reduced functionality mode, despite earlier assurances that Office 2019 installs would continue to work after support ended.

The episode highlights growing tension between perpetual licenses and software that still depends on remote validation infrastructure. If accurate, it could fuel consumer-rights scrutiny and push buyers to question whether “one-time purchase” software can be meaningfully owned when core functions can be disabled later.
