Con Requires maintenance
You have to manually keep the server and clients up to date.
Con Old versions and deleted files aren't available online, just on one computer.
On some other services you can see previous versions and deleted files for a time, but with OneDrive, these are only available on the computer the edit was made. So if someone who has write permission on your shared folder deletes your stuff you just have to ask them to go in their recycle bin (and hope they didn't empty it!), which makes it less useful for teams.
