That gives me this error. 
 
Method invocation failed because [System.Management.Automation.PSMemberSet] doesn't contain a method named 'put'. 
At E:\Exchange Server\Scripts\NewUser.ps1:188 char:10

</div>

<div>
that would be because you did this $user = ([ADSI]&quot;LDAP://$a8&quot;).psbase 
 
Here is the complete code. 
 
I am a little confused why your doing what your doing though.

I am doing this because I have 3 companies using the same exchange server. &nbsp;They have the same owners, but they want the companies to look separate. &nbsp;Two of the companies have less then 10 people. &nbsp;To save myself on hardware and software cost I decided to use one Exchange Server for all 3 companies. &nbsp;However, this means I need separate GALS. I can accomplish this with Address Lists and Security Groups. &nbsp;OWA gets is Addresses List differently then the Outlook Client. So the article (<a href="http://technet.microsoft.com/en-us/exchange/bb936719.aspx" rel="ugc">http://technet.microsoft.com/en-us/exchange/bb936719.aspx</a>) told me I need to modify msExchUseOAB and msExchQueryBaseDN. 
 
Please if you know an easier way to accomplish what I am trying to do, I am all ears. Here is the script for adding a new user. As you can see this is quickly becoming a nightmare. 
 
Thank you,

You cannot call a method on a null-valued expression.

<div>
That implies this line fails. Is $a8 a valid dn? 
 
$user = [ADSI]&quot;LDAP://$a8&quot; 

</div>

<div>
Sorry I rem'd that line out instead of removing the .psbase. &nbsp;I'm back to this error again

<div>
This goes back to what I talking about before &quot;A constraint violation occurred&quot; is actually returned by the Domain Controller. It implies the data you tried to write was not valid. 
 
I bet the value of $a7 is not what you think it is. 
 
Put this in your script just prior to the call to see what it is trying to write 
 
Write-Host &nbsp;&quot;ou=$a7,ou=Companies,dc=contoso,dc=com&quot;

<div>
I put a 5 second delay in before the 
&nbsp; 
$a1 = get-mailbox $UserAlias 
 
It is working now. 
Thank You.
