I’ve used the onedrive-abrunegg client in the past.
It works well with any file manager as it maps one’s onedrive account to a physical directory on one’s local computer. However, at the level it operates, it doesn’t really provide much feedback through a Dolphin.
I ended up buying the insync client – which works a bit better than the abrunegg client and far better than the kio-gdrive client (and its gnome equivalent). It supports onedrive/google/dropbox and integrates with the major file managers like Dolphin.
Unfortunately, it does cost money – so it’s not for everyone.
EDIT: I use the client to access my work’s onedrive account. For personal stuff, I use the cloud storage option on my mailbox.org account. It uses “webdav/davfs2” which does not require a separate client.
