Possibility to map a azure file storage via GPO
Momently its not possible to map a azure file storage share via GPO, because the two fields for username and password are greyed out.

Can you provide more details on your scenario? Do you need to persist the shares after a reboot of a VM? (here's a older blog post on how to do this https://blogs.msdn.microsoft.com/windowsazurestorage/2014/05/26/persisting-connections-to-microsoft-azure-files/)
