How to allow mount drive to Azure file store

I am trying to mount drives to my Azure file stores using:

New-PSDrive -Name Z -PSProvider FileSystem -Root "filestorename" -Persist

It is blocked and I can only do this if I take out the Firewall entirely. When I do this I then can't add a rule because it is diabled! (Developers, can we add rules even when Firewall not active?) So, I remove the drive, set the Firewall to on and now, what rules do I need to add please? Nothing is blocked by rules.
