Office 365 - Convert between Immutable ID and AD Object

Two quick scripts to convert between ImmutableIDs and AD Objects with pipeline capability.

function get-ImmutableIDfromADObject
{
    [CmdletBinding()] Param(
        [Parameter(Mandatory=$True,ValueFromPipeline=$True,ValueFromPipelinebyPropertyName=$True)]$ADObject) 
   process{ 
        if (!$ADObject.objectguid){$ADObject = get-adobject $AdObject -properties objectGuid}
        [system.convert]::ToBase64String($ADObject.objectguid.tobytearray())
    }
}

function get-ADObjectFromImmutableID{
      [CmdletBinding()] Param(
        [Parameter(Mandatory=$True,ValueFromPipeline=$True,ValueFromPipelinebyPropertyName=$True)][string]$ImmutableID)
   process { get-adobject  ([guid]([system.convert]::FromBase64String($ImmutableID)))}
}
