Microsoft Exchange extends the default Active Directory schema with some additional attributes, also known as custom attributes.
These extra free fields are very handy, we use them for example for third party applications,employee identification numbers etc.
Recently we migrated to Exchange 2010, nice but the Exchange Management console 2010 is not supported on 32bit versions of Windows (we still use Windows XP 32bit). The only way to edit the custom attributes is through the Microsoft Exchange Management Console.
So I had two options, either give support personnel access to the one of the Exchange servers or create some script to do it. I chose the latter.
This Powershell script (with a nice GUI) allows you to edit custom attributes from any workstation (either Windows XP, Windows Vista or Windows 7 32bit or whatever runs Powershell 🙂 )
Here’s an impression of the script’s GUI:
And here is the (very long) Powershell code:
