OneDrive® for Business
If you want to connect to OneDrive® for Business follow the above steps, but make sure you're the account admin. If you're not the account admin, please ask your OneDrive® account admin to create the link between SmartDraw and OneDrive® for the connection to work properly. When an admin links their OneDrive® account to the SmartDraw license, they will be given the option to authorize the connection for everyone in their domain.
Please also make sure that your OneDrive® account allows third party apps to be connected to it or whitelist SmartDraw's app.
