@Glenn Maxwell Welcome to Microsoft Q&A, thank you for posting your here!!
In order to use an Azure file share via the public endpoint outside of the Azure region it is hosted in, such as on-premises or in a different Azure region, the OS must support SMB 3.x. Older versions of Windows that support only SMB 2.1 cannot mount Azure file shares via the public endpoint.
You can also use AzFileDiagnostics
to ensure that the Windows client environment has correct prerequisites. AzFileDiagnostics
automates detection of most of the symptoms mentioned in this article and helps set up your environment.
Hope this helps!
Kindly let us know if the above helps or you need further assistance on this issue.
