Attempting to map two separate dropbox accounts and the mapping refuses to change to the other account
You can login to multiple cloud storage accounts. To setup multiple accounts, create the Dropbox account site profile as normal. Then, go to Internet Explorer and log into the same Dropbox account and then log out (also be sure to be logged out of any Dropbox account in any browser). Then, create the second Dropbox account site profile in WebDrive. Then, you can connect both. You can continue this for any additional site profiles to be created, just ensuring to log in through Internet Explorer and then logging out for each one.
The same procedure would apply for Google Drive, OneDrive, OneDrive for Business, etc.
