In college right now 2yr computer science, anything Microsoft is a pain to work offline. I miss the onedrive sync in windows i just use syncthing for that now .
I use onlyoffice since it has one of the best Microsoft office compatibility though I submit my obsidian export as a pdf for my assignments or records.
If you really need ms office or for group projects and you have an o365 account, just use the web version for it.
