If you get this error, make sure your version of the Exchange Management Console is equal to, or higher than the Exchange version you’re connecting to. In my case, I was connecting with an EMC 2010 SP0 to an Exchange server with SP1 installed.

You can verify that your version is incompatible by specifying a single server as Exchange forest. To do so, follow these steps:

  1. In your EMC, right click “Microsoft Exchange” (top node) and click “Add Exchange Forest
  2. As a friendly name, type in any name you want. in The FQDN field, type the name of your Exchange server. Click OK.
  3. A new window will prompt you for credentials. Type in a username and corresponding password, that has access to your Exchange organization. For example the Exchange Administrator Account.
  4. In the EMC, click the node you just created. A new error will occur:
  5. Initialization failed
    The following error occurred while attempting to connect to the specified Exchange server ‘servername':
    Unable to connect to version 14.1.289.7 server using version 14.1.270.1 due to potential compatibility problems. To resolve this issue please remove this sub-node from the console tree and re-add it specifying a server with a matching version. Click here to retry
