Hi,
With regards to your query, it seems that you have upgraded from backup Exec 8.x to 10.0. In order to backup and protect a remote exchange server, you need to have the exchange agent license installed on the local server and a remote agent installed on the remote exchange server. The exchange component is installed on th elocal server itself and contact through the remote agent in order to protect exchange server.
In order to be able to restore at a single message level, you will have to backup exchange's mailbox store but in order to protect the exchange server from a disaster recovery, you will need to backup the information store and the system state. For more information, please refer to the admin manual. You candownload the manual from the following link and refer from page no: 1141
