1. You must see the domain controller get Kerberos Ticket – yes it is possible from a non-domain joined computer
please remember it must be AD or ADDS domain FQDN not a Pre-WIndows 2000
2. Open Share using e.g. \\azureshare.file.core.windows.net\shared and provide username as FQDN from the previous command and username like mytest.onmicrosoft.com.onmicrosoft.com\mf
4. You should have access – you can verify tickets using klist.
