Microsoft Forces Office 2019 for Mac Users to Upgrade as Certificate Expires

Microsoft's refusal to renew a certificate for Office 2019 for Mac will force millions of users who paid one-time license fees to either upgrade to Microsoft 365 or lose editing capabilities. Starting July 13th, the app will enter 'reduced functionality mode,' allowing users to open files but preventing them from editing, saving, or creating documents. This move contradicts Microsoft's earlier assurance that Office 2019 apps would 'continue to function,' exposing the company's aggressive pivot toward subscription-based monetization over legacy software support.
