Please let us know if you have feedback on this feature or encounter any issues. This policy can be used with DiskSpaceCheckThresholdMB as well as DefaultRootDir. If you disable this setting, OneDrive will not attempt to automatically sign in users. The new sync client will attempt to import the user's sync settings from the previous sync client. If you enable this setting and the user is using the previous OneDrive for Business sync client, the new sync client will attempt to take over syncing. OneDrive will attempt to sign in on every account on the computer and once successful, that account will no longer attempt silent configuration.
The threshold for which the user is prompted can be configured using DiskSpaceCheckThresholdMB. It will check the available disk space before syncing, and if it is large, OneDrive will prompt the user to choose their folders. If you enable this setting, OneDrive.exe will attempt to sign in to the work or school account using these credentials. This policy lets you configure the OneDrive sync client silently using the primary Windows account on Windows 10, and domain credentials on Windows 7 and later. Download and open EnableADAL.reg to enable ADAL and restart the sync client. Important: If you enable this setting, ADAL (Azure Active Directory Authentication Library) must be enabled or the account configuration will fail. Both of these features are now in preview.
The second was the ability to let you set the maximum download throughput rate for computers running the OneDrive sync client.
The first was Silent Sync Account Configuration for OneDrive which will allow you to silently configure OneDrive using Windows 10 or domain credentials for Windows 7 and Windows 8 on the first run. At Ignite, we announced two new features for IT Administrators.
