Nice! Thank you.

Ok... I tried this.  I only added the portion Script for User Objects, imported it and created a new provisioning policy to execute this script. I applied it to my test OU.

When I create a new user in my test OU - the checkbox to Create an Exchange mailbox is still enabled. 

Any ideas?

function onGetEffectivePolicy($Request)
{
if($Request.Class -ne "user"){return}
$Request.ClearEffectivePolicyInfo("edsaCreateMsExchMailbox", $Constants.EDS_EPI_UI_AUTO_GENERATED)
$Request.ClearEffectivePolicyInfo("edsaCreateMsExchMailbox", $Constants.EDS_EPI_UI_GENERATED_VALUE)
$Request.SetEffectivePolicyInfo("edsaCreateMsExchMailbox", $Constants.EDS_EPI_UI_GENERATED_VALUE, $FALSE)
$Request.SetEffectivePolicyInfo("edsaCreateMsExchMailbox", $Constants.EDS_EPI_UI_AUTO_GENERATED, $FALSE)
}

Odd that this is not working.

Another (codeless) way I have done this in the past is to use a PVG (Property Value Generation) policy rule to set edsaCreateMSExchMailbox to $false - i.e. "edsaCreateMSExchMailbox must be FALSE".

So just add a PVG rule to the provisioning policy you linked to your test OU that contains the above PVG rule.

That worked... and much simpler.

THANKS!!
