Microsoft’s messaging on the subject hasn’t done it any favors, either. Its end-of-support page for Office 2019 for Mac, originally posted in October 2023, once told owners to “Rest assured that all your Office 2019 apps will continue to function.” A revision now dated May 15, 2026 has dropped that line, replacing it with a note that their data “can be accessed in a supported Microsoft 365 or Office product.”



I think you were downvoted because Euro Office has made the mistake of supporting Microsoft document formats above all else and don’t have good support for the ODF alternatives at the moment.
They have since said they want to do better, but they’re off on the wrong foot.

Yeah, but if they don’t do that, supporting the OOXML format by default, nobody will switch, and it will become another failure.
