We've recently deployed OneDrive for Business for a customer and we set up the client sync restriction to the domain GUID. There seem to be some HUGE issues with the feature to make me think it's buggy.
Issue #1 - Random computers on the "allowed" domain are not recognised as such and clients are denied sync. The error thrown is "Sorry, OneDrive can't add your folder right now." Furthermore, Fiddler shows an HTTP response "X-ClientErrorCode: MachineIsNotAllowedToSync".
Issue #2 - Users randomly get a problem in Office ProPlus when opening OneDrive files. For example, in Excel, going to the "Open" menu item and select OneDrive as the storage location, they are prompted for credentials to sign-in. When they enter correct credentials, the error thrown is "That Microsoft account doesn't exist. Enter a different account or get a new one."
For both of these issues, disabling the OneDrive for Business client restriction fixes the problem immediately. I've also tested affected client computers both on the local network (which has a proxy) and direct Internet access.
Anyone seen this behaviour? I'd love to see some documentation on how the domain GUID is confirmed at the client-side to point me in the right direction.
