Excel Desktop update required to connect to Power Platform Analytical Dataflows

Excel Desktop must be updated to Build 16.0.17932.20732 or newer by May 27, 2026, to maintain connectivity with Power Platform Analytical Dataflows.

Introduction Action required: We are updating the Power Platform Dataflows connector in Excel Desktop to improve reliability and support future enhancements. To avoid disruption, organizations who use Power Platform Analytical Dataflows connector must update Excel Desktop to a supported build before this change rolls out, as older versions will no longer be able to connect to Power Platform Analytical Dataflows. When this will happen: The required Excel Desktop version (Build 16.0.17932.20732 or newer) is available as of April 27, 2026 (the publication date of this post).
