We are going through the exercise of rebuilding our GW2014sp2 postoffice from the backup. The scenario we are using is a new server with the backup data, so install the software on a new server, then copy the domain and postoffice data and configure. My question is do we need ldap if all we want to do is go in and check people's mailboxes? we won't be processing any mail. Assuming we need ldap, can we backup/export the ldap from eDirectory and install ldap on the recovery server?
