OneDrive can be used as a storage for Version Control and Web Catalogs. Connecter uses an application-specific folder to store its data, so it's isolated from the other data of the user. For now, it works only with Personal Accounts. If you have a business account, you cannot use this storage provider.
The setup is simple. The user only has to log in if they aren’t already and authenticate Connecter. The tricky part is that the user needs to be logged in with the account that Connecter will use to store the data before giving it access. Sometimes Microsoft will show the screen for selecting an account even if the user is logged in.
