Backup Exec 11d does not backup .EDB & .STM files to tape

[tuant]

I'm having issues using BUE 11d to backup the exchange server 2003. It will not backup the files priv1.edb and priv1.stm in the 'MDBDATA' folder. Files are selected in the job selection list and have an exchange license installed on BUE. Also modify the registry the other night to 'exclude active files' (something in found while roaming on Symantec forums). Neither changes worked. The files appears to be locked because they are *greyed out in BUE. Though they are check, I can't un-check it like the other flat files.
