@Robert Garlington Welcome to Microsoft Q&A Forum , Thank you for posting your query here!

Can you please share the screenshot of the error message?
Could you clarify if it's an SMB or NFS volume?

To set ACLs for Azure NetApp Files volumes using PowerShell, you can follow these steps. This process involves using the Set-Acl cmdlet to manage the access control lists for your ANF volumes.

Connect to Azure: First, ensure you are connected to your Azure account.

Connect-AzAccount

Retrieve the ANF Volume: Get the details of the ANF volume you want to set ACLs for.

$anfVolume = Get-AzNetAppFilesVolume -ResourceGroupName "<ResourceGroupName>" -AccountName "<AccountName>" -PoolName "<PoolName>" -VolumeName "<VolumeName>"

Retrieve the Current ACL: Get the current ACL for the volume.

$acl = Get-Acl -Path $anfVolume.MountPath

Create a New Access Rule: Create a new access rule for the user or group you want to grant permissions to.

$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule("<UserOrGroup>", "FullControl", "Allow")

Apply the Access Rule: Add the new access rule to the ACL.

$acl.SetAccessRule($accessRule)

Set the Updated ACL: Apply the updated ACL to the volume.

Set-Acl -Path $anfVolume.MountPath -AclObject $acl

This process should help you manage ACLs for your ANF volumes using PowerShell.
