I am installing "Exchange Server 2010" on a "windows server 2012" system. As exchange installation prerequisites we have to prepare "Active Directory" but I already installed a Active Directory in other system. So my question is can use my existing Active Directory for exchange installation? if yes , how?

I am new to exchange server installation....

  • Please don't tell me that you only have a single domain controller for your AD where you're building Exchange.

  • The Exchange Server installation will run the necessary Ad prep for you. There's no need to run it manually. The Exchange server needs to be a member of the AD domain into which you want to install Exchange.

Yes, you can use your existing AD infraestructure. The exchange installation is going to require an additional step in the DC:

Launch an elevated command prompt and run the following command:

D:\setup /PrepareAD

(asuming that you have the Exchange installation CD in D:)

  • No, you don't need a new AD, use the existing one. Aug 29, 2014 at 14:48

I know someone else is going to say this, so I'll say it first: it sounds like you are in over your head. Hire a professional to set this up for you. This is one of the simplest prerequisites for setting up Exchange, and it only gets more complicated from here.

To answer your question, Exchange needs to update the existing Active Directory schema with its own metadata and information in order for Exchange to work. So no, you do not need a separate AD infrastructure.

    The existing AD. Please slow down and read the answers, and Microsoft's own documentation. It's very explicit.
