Previews for Silent Sync Account Configuration and Bandwidth Throttling for OneDrive

Thanks Ryan, this helps but only slightly.

I'm mostly concerned with deployment the Document Libraries and at this time I cannot find a supported way to do this.

It appears that the data is stored in 2 places

%localappdata%\Microsoft\OneDrive\settings\Business1\<ScopeIdGuid>.ini 

and in the registry under

HKEY_CURRENT_USER\Software\Microsoft\OneDrive\Accounts\Business1\ScopeIdToMountPointPathCache 

REG_SZ <ScopeIdGuid> <Path to sync location>

It _looks_ like the values in the registry control the sync engine while the values in the <ScopeIdGuid>.ini control the Nav Pane in Windows Explorer.

However, Fiddlering the web requests, I cannot figure out how to get the <ScopeIdGuid> itself. It doesn't appear in any of the web requests.

The next best option would be to replicate what happens when the user clicks the Sync button on a document library. It uses the odopen:// protocol route with a bunch of parameters, meaning we could feasibly run Powershell as a logon script like this:

Start-Process "odopen://sync/?
userId=<UserGuid>
siteId=<SiteGuid>
webId=<WebGuid>
listId=<ListGuid>
userEmail=<upn>
webUrl=<url>
isSiteAdmin=0
onPrem=0"

The SiteId can be found programtically using 

$context = New-Object Microsoft.SharePoint.Client.ClientContext("https://tenant.sharepoint.com/teams/eric")
$context.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($credential.UserName,$credential.Password)
$site = $context.Site
$context.Load($site)
$context.ExecuteQuery()
$site.Id

However at this moment I can't figure out how to programatically determine the WebId and ListId parameters. The call doesn't work without them.
