Update Microsoft 365 Office Apps to Version 16.0.18827.20202+

Message ID: MC1127222

To ensure continued high-quality performance of the Read Aloud, Transcription, and Dictation features in Microsoft 365 Office apps, we’re upgrading the backend service that powers these capabilities. As a result, these features will no longer function on Office clients running versions earlier than 16.0.18827.20202 after January 2026. When this will happen

General Availability (Worldwide): End of January 2026
General Availability (GCC, GCC High, DoD) End of March 2026

How this affects your organization

If your organization is using Microsoft 365 Office apps with version numbers lower than 16.0.18827.20202, users will lose access to Read Aloud, Transcription, and Dictation features after the dates listed above.
There is no change to the user experience for clients on supported versions.

What you can do to prepare

To avoid service disruption, ensure that all Office clients are updated to version 16.0.18827.20202 or later before the applicable deadline.
