Create Office 365 group for existing Team site
do you have the Active directory read and write permissions in the app only context? as you need them as well.
I've added Application permission Read and write directory data (Directory.ReadWrite.All), but it doesn't make a difference.
Group.ReadWrite.All is added as Delegated permission as it doesn't exist as Application permission. Does this mean that it isn't possible to use an AppOnly context (no user context).
Please take a look at the site of John as he managed to do this http://johnliu.net/blog/2017/1/create-many-o365-groups-with-powershell-resource-owner-granttype-and-microsoft-graph

Appreciate it, however I don't see that there's an API for this in the Graph. Sure you can create a Group, but I need to "groupify" an existing SharePoint site collection.
The SharePoint API is
{siteUrl}/_api/GroupSiteManager/CreateGroupForSite
But again, it cannot be called using AppOnly context.
I guess the conclusion is that it is not possible yet.
