MAC Address not available via SDK

[clickbangdead]

In December, Intune added Ethernet MAC Address as a property (finally!). It's available via hardware properties in the portal, but if I retrieve devices using:

$a = Get-IntuneManagedDevice | Get-MSGraphAllPages

I get an empty ethernetMacAddress field on all devices. I am able to get the data if i directly query via REST like so:

$DeviceID = <some Device's ID>
$URI = [uri]::EscapeUriString("https://graph.microsoft.com/beta/deviceManagement/manageddevices('$deviceid')?`$select=UserPrincipalName,emailAddress,deviceName,model,manufacturer,serialNumber,id,lastSyncDateTime,ethernetMacAddress&_=1576515130721")
$dev = Invoke-MSGraphRequest -url $uri -HttpMethod get

Then i am able to get the ethernetMacAddress property

If I do:

Get-IntuneManagedDevice -Select id,ethernetMacAddress | Get-MSGraphAllPages I get:

Get-DeviceManagement_ManagedDevices : Cannot validate argument on parameter 'Select'. The argument "ethernetMacAddress" 
does not belong to the set "id,userId,deviceName,managedDeviceOwnerType,deviceActionResults,enrolledDateTime,lastSyncDateTim

I tried your example of

$DeviceID = <some Device's ID>
$URI = [uri]::EscapeUriString("https://graph.microsoft.com/beta/deviceManagement/manageddevices('$deviceid')?`$select=UserPrincipalName,emailAddress,deviceName,model,manufacturer,serialNumber,id,lastSyncDateTime,ethernetMacAddress&_=1576515130721")
$dev = Invoke-MSGraphRequest -url $uri -HttpMethod get

I get the error message: Parsing OData Select and Expand failed: Could not find a property named 'ethernetMacAddress' on type 'microsoft.graph.managedDevice'.

Are you sure this property exists?

I have hit this same issue today. Example:

$intuneDevices = Get-IntuneManagedDevice | Get-MSGraphAllPages $intuneDevices[0]

Returns an object with property (see below), but I receive the same error as @clickbangdead when using the select parameter with the property included.

Possibly that the set validation needs to be updated with the new property?
