To create the MESO container

  1. At a command prompt on the computer that is running Exchange 2007, type the following command, and then press ENTER:

    setup /prepareDomain

  2. Click Start, click Run, type services.msc, and then click OK.

  3. In the Results pane, find the Microsoft Exchange Information Store service.

  4. Right-click the service, and then click Restart.
