Backing Up Exchange 2003 DB

Hi All, New to Acronis (previously using Veritas Backup Exec). Not sure which forum to post this. But I recently purchased license for the following:

-Acronis Backup & Recovery 11.5 Server for Windows incl. AAP
-Acronis Backup & Recovery 11.5 Microsoft SQL Server Add-on incl. AAP
-Acronis Backup & Recovery 11.5 for Microsoft Exchange Server incl. AAP

I was able to apply all the license successfully. I currently have Backup and Recovery 11.5 Server on my Windows 2012 Server. I was able to install and apply the license on my MS Exchange server (On a separate server hardware). My problem is when I set up to backup for Exchange DB I don't see it in the "what to backup" option. Am I doing something wrong? Please help.

Thanks all.
