I've already accomplished this in the past but for whatever reason, I am unable to find my notes or any information on the web regarding creating an Exchange 2010 LAB with a blank database. What I did is clone my Exchange 2010 server without the Database disks and now I would like to empty the database and re-attach it. The only information I found regarding was creating a DialTone database but this does not allow me to connect with my existing LAB AD users to their respective empty mailboxes. From what I recall in the past, it was a simple command, possibly ESEUTIL but not sure. Hope that's clear and that someone can provide me with some guidance? Thanks.
