One Drive not Automatically Signing In with Email

Hi All,

I'm having an issue where I'm trying to get One Drive to automatically log in when a user logs into a Windows 10 laptop using Group Policy. The windows laptops have conditional access configured and are hybrid joined, and I have confirmed when running 'dsregcmd /status'  I can see "AzureAdJoined : YES".

Through our on-premise GPO I've tried configuring Computer>Admin Templates>OneDrive and enabled and disabled the "Silently Sign in User into OneDrive" - with no luck.  I've also tried adding the below registry keys.

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\OneDrive] “SilentAccountConfig”=dword:00000001. 

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\OneDrive] “EnableADAL”=dword:00000001 – This setting enables Modern Authentication for OneDrive.

One thing to note is the on-premise UPN is different to that of the o365 email address used to log into MS apps. I would be very interested to know if anyone has managed to get this type of setup to work? 

No matter what I try, I find I have to launch One Drive manually and go through the setup screen. I enabled some of the other setting like disabling users from configuration folder location etc. with no luck.

Any pointers or past experience dealing with this would be appreciated!
