Exchange setup /PrepareAD /OrganizationName

Quick Blog on Exchange, Oh man I miss blogging.

So here I am, helping a Exchange 2013 deployment client side at their production (really, long story about production) when they asked me – What’s an example value for the /OrganizationName parameter with the preparead on setup?

Right after the /PrepareSchema Command (or PS)


We will run:

setup /PrepareAD /OrganizationName:<organization name>

And client said, there are no example in


Actually, they just need to enter their a resemblance of their company name.

An examples are

setup /PrepareAD /OrganizationName:VFTSINC

setup /PrepareAD /OrganizationName:YOURCOMPANY

setup /PrepareAD /OrganizationName:CONTOSO


On and don’t forget these:

1. Add yourselves to Enterprise AND Schema Admins Security Group! Yea the prompt will tell you and/or but based on experience, it should be AND. Then I read the TechNet article again and it says, Schema AND Enterprise Admin group.

2. Run as Administrator the CMD prompt

3. Nah, don’t bother coming up with a way to put spaces on your organization name. We tried a lot of examples, quotes, double quote or without it but only the ones on the screenshot below worked. We made sure that no spaces before and after the name as well, if you had to ask me if I did try that and didn’t worked.


3. Include the /IAcceptExchangeServerLicenseTerms

4. We do not know what happens if we closed the command prompt while the schema is being extended. Be sure not to accidentally click it.


Finally on the setup on /PrepareAllDomains step, we opted to have the IAccept parameter again. So  that’s it!

Happy exchange deployment and my I say the traditional, You had me at EHLO 🙂

One thought on “Exchange setup /PrepareAD /OrganizationName”

  1. If you really need a space in the organization name you can do it quite simple by using PowerShell:

    PS D:\> $Org = “My Organization”
    PS D:\> & .\Setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms /OrganizationName:$Org

    Apparently PowerShell does some magic when parsing arguments to applications, that cmd.exe can’t do.
