Many orgs work on Google accounts, so asking for a microsoft account is an additional hurdle. It also probably requires I upload the files to my OneDrive. I had a look at the interface and had no idea how to just open a document I have locally.
I get your point that it's totally doable (and also free up to some point. The OneDrive space is the limit ?). I'm not convinced it's simple though.
