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.”
Euro-Office
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.
They could have supported both by default.
Someone somewhere made the decision to concentrate on OOXML to the exclusion of everything else, either clueless as to how that would look, or hoping that few people would notice and the fall-out would be minimal.
Either way, neglect of the open alternative is not a good look.
I thought OnlyOffice has good odf support? Did the fork patch it out?
There might be any one of a number of confusions here, depending how I read your comment. Or there are none at all. Hard to be sure. But for clarification’s sake:
Euro Office is not OnlyOffice. OnlyOffice is not OpenOffice, which is essentially defunct but was the most popular suite that first adopted ODF. OnlyOffice may have been named that way to lure people away from OpenOffice, which was, and is, still in use in some places despite a better non-proprietary option being available. Namely:
LibreOffice is the successor to OpenOffice and uses ODF as its default, so its support is 100%.
OnlyOffice supports* ODF too, but it’s by far not the, uh, only one.
* According to their specifications anyway. I haven’t used it to be able to confirm how good their support is.
But EuroOffice is a fork of open source OnlyOffice?
And about ODF; well, it was first (standardized), then MS panicked and made their own version. But with foot angles and it shoots you in the face, because MS ignores their own defective pseudo-standard nowadays.
LibreOffice have specifically called them out, so I guess the support isn’t as good for ODF as it is for Microsoft’s OOXML.

I’m looking forward to giving it a whirl. I interact with other humans when sharing and developing documents, so intercompatibility with the office and Office 2003 standards is literally the second most important thing for me, and all of the arbitrary also-ran file formats are a nice to have, not a need to have.
As evidenced by the fact that even the centers can’t get on the same page about what alternative formats they feel should be mandated instead.
