I think the files edb and stm are wrong, in fact the private mailbox folder and public mailbox folder doesn't appear anything. I have created backup of the mail accounts into every machine of my users with the .pst files. I would like to know how to restore my mail accounts and how to create new private and public mailbox folders.Regards.

Wow! That's a pretty generic post. We need more detail to try and assist. Is Exchange functioning? Are users able to send email?
