Running powershell script as custom Activity

[AsheeshG]

Hi,

I am using a PowerShell custom activity that creates ad group . I have some validations which throw error back.

Example 

if (@($AccountOwnerObject).count -gt 1) {
Throw "FAIL: Multiple accounts found for CA Account Owner $PrivilegedAccountOwner"
}

So when this is executed my output is Null. When i use 

if (@($AccountOwnerObject).count -gt 1) {
Write-Host "FAIL: Multiple accounts found for CA Account Owner $PrivilegedAccountOwner"

return
}

I get the output. 

The script is running on MID server.

Let me know where i am going wrong.

I am on Washington DC.

Thanks in advance.
