This TechNet Wiki is based on the forum post: Convert the Bytes Array to String using PowerShell

Issue/Requirement

Can't return string for msExchMailboxGUID

Explore AD Properties

$user = Get-ADUser -Identity 12345 -Properties *

$user.msExchMailboxGuid.GetType().FullName 

$user

Returns: System.BYTE[]

Solution

$string = (Get-ADUser -Identity '12345' -Properties *) 

$bytes = [System.Text.Encoding]::Unicode.GetBytes($string.msExchMailboxGuid) 

[System.Text.Encoding]::ASCII.GetString($bytes)
