Microsoft has confirmed that several popular Office 365 features will stop functioning in older app versions starting January 2026, marking a significant shift in its software lifecycle approach. The features affected—Transcription, Dictation, and Read Aloud—will no longer work due to a backend service update, with Microsoft making it clear that this change will require users to install a mandatory update for the first time. While Transcription and Dictation are limited to Word, the Read Aloud function spans multiple apps, including Word, Outlook, PowerPoint, and OneNote, making the change impactful for a broad range of users.
To retain access to these tools, users will need to update to Office version 16.0.18827.20202 or newer before the January 2026 cutoff. Microsoft is advising IT admins to act well ahead of the deadline by assessing their organizations’ current Office versions and ensuring timely upgrades. The update process is designed to be straightforward, but it will also deliver new features, improved security, and broader compatibility, adding incentive for users to move forward.
This decision aligns with Microsoft’s strategy of reallocating resources from outdated services to enhance current offerings. For those who do not update, the immediate loss of these features is just one risk—continued use of unsupported software also exposes systems to security vulnerabilities and compatibility issues. While Microsoft 365 remains the most direct path for uninterrupted access, some users may consider shifting to other modern office suite alternatives.
