Creation of groups - number added to pre 2000 name

Question

_{Wednesday, March 15, 2017 11:30 AM}

Running Exchange 2016 CU3 in an Windows Server 2008 R2 domain functional AD.

When creating a new security group via Exchange Admin Center, the group is created fine but when I look at in Active Directory Users and Computers the group name (pre windows-2000) has a - and a ten digit number added after the name I set.

Does anyone know why and how I can stop this?

I can go in afterwards and remove the number but it just adds another step.

Thasnk for your help,

Mrtro

Hi 

Pre windows 2000 is the samaccountname of an object 

This can be changed latter and will be an extra step 

You can also create Security groups via Powershell and in that way it would be one time activity 

New-distributiongroup -name "Classic" -Type "Security" -Samaccountname "Classic"  -members [email protected],[email protected] -Primarysmtpaddress [email protected]

Hi,

Based on my knowledge, it was added by default. For now, I didn't find some solutions to stop this behavior. But I have some workarounds.

• Create Security Group via EMS as suggested above.
• Use Cmdlet Extension Agent with the following steps:

1. On all Exchange Server 2016, find the %ExchangeInstallPath%Bin\CmdletExtensionAgents\ScriptingAgentConfig.xml.sample file, rename it to ScriptingAgentConfig.xml (Backup the original file)
2. Open renamed file, remove all the content and add the following script.
3. Enables the cmdlet extension agent named Scripting Agent: Enable-CmdletExtensionAgent "Scripting Agent"
4. Restart IE and try to create a new security group via EAC.

Script:

<?xml version="1.0" encoding="utf-8" ?>

<Configuration version="1.0">

   <Feature Name="MailboxProvisioning" Cmdlets="New-DistributionGroup">

     <ApiCall Name="OnComplete">

       If($succeeded) {

         $mbx = $provisioningHandler.UserSpecifiedParameters["Alias"]


     Set-DistributionGroup $mbx -SamAccountName $mbx

       }

     </ApiCall>

   </Feature>

</Configuration>
