Get License information

[BZDEX1979]

Hi All,

I need assistance obtaining information about temporary licenses.

function Get-ESXiHostInventory {

    param (

        [Parameter(Mandatory = $true)]

        [VMware.VimAutomation.ViCore.Impl.V1.Inventory.VMHostImpl]$vmHost

Did you mix up the "Valid (Permanent)" and "Valid (Temporary)" licenses?
When the $expirationProperty is empty it indicates a "Product Evaluation" license afaik.

I changed the approach and I'm able to get the required details:

function Get-ESXiHostInventory {

Thank you @LucD

How to mark the thread is solved ?

[LucD]

On someone's reply, there are 2 options, "Mark best answer" and "Close thread".
Not sure if both are needed.
