We have been managing Exchange 2010 from a separate Windows 2008 R2 server and recently upgraded the management machine to Windows 2012 R2. The EMC works fine but I am somewhat limited in the shell. Once it remotes to the CAS server, it drops to PS version 2 (as expected) but then I can no longer import the ActiveDirectory module on the 2012 box because it demands version 3. This is bad because I have several scripts that use AD as well as Exchange modules.

Is it possible/supported to install the older version of the RSAT on Windows 2012? Or at least get the older ActiveDirectory module?

I know that this sounds like a simple question that google would answer but I'm not finding it. Thought I'd see what you guys know :-)

The error message is on the bottom but I believe this is not helpful. The problem seems to be that the module wants version 3. It imports successfully if I run powershell locally. Only when I remote into the exchange server (and it drops to version 2) does it refuse to load.

  • Could you add the specific error message to your question? – dbr Apr 10 '15 at 21:50
  • I know you can't install the old RSAT on windows 8 so my guess is you can't put it on 2012 either. – Todd Wilcox Apr 14 '15 at 1:27

I don't believe you can install the Windows 7/2008 R2 RSAT on 2012, but if you're using an account that has access to an endpoint on a domain controller (or really any other server with the AD management/RSAT installed), and PowerShell remoting is enabled, you could use implicit remoting to pull those cmdlets into your own session:

$SessionParameters = @{
    ComputerName = <server with AD management tools installed>
    Name = 'Microsoft.ActiveDirectory'
    Authentication = 'Kerberos'
    ErrorAction = 'Stop'
$Session = New-PSSession @SessionParameters

$InvokeProperties = @{
    ScriptBlock = { $env:ADPS_LoadDefaultDrive = 0; Import-Module -Name 'ActiveDirectory' }
    Session = $Session
    ErrorAction = 'Stop'
Invoke-Command @InvokeProperties

$ImportProperties = @{
    Session = $Session
    Module = 'ActiveDirectory'
    ErrorAction = 'Stop'
[void]Import-PSSession @ImportProperties


You can do the same thing with Exchange if you wanted to run scripts from a separate server without having any tools installed altogether (and therefore would be able to manage any Exchange environment):

$SessionParameters = @{
    ConnectionURI = "http://<Exchange server>/PowerShell"
    ConfigurationName = 'Microsoft.Exchange'
    Authentication = 'Kerberos'
    ErrorAction = 'Stop'
$Session = New-PSSession @SessionParameters

$ImportParameters = @{
    Session = $Session
    ErrorAction = 'Stop'
[void]Import-PSSession @ImportParameters


This also has the added benefit of not being dependent on upgrading Exchange to use a new version of PowerShell (version 3+ with Exchange 2010 comes to mind), but with the con that all objects referenced by implicit remoting are deserialized.

  • Awesome! I'll have to update a lot of scripts but at least I'll be able to use them. Thanks – bob Apr 14 '15 at 13:35
