>Teams is another one I don't even want to get started on.

At least this one is actively used by most companies (at least outside of IT/devs firms) and they generally find it acceptable.

OneDrive on the other hand... Even when I was an IT consultant, I haven't met a single person who has tried it and didn't absolutely hate it. I have seen employees playing out of pocket for dropbox or gDrive even when OneDrive came for free with the MS Office subscriptions provided by their employer because of how frustrating it was to use and work mysteriously disappeared or got corrupted on a regular basis.
