I think you have to run the EXCDSMC /ADSMAUTODELete command. 

By the way, I tried using "BACKUPEXEC's ADSM option to backup EXCHANGE"
but I did not succeed.
I installed everything according to the BackupExec documentation. TSM is
3.7.2.
I created the suggested storagepools, policy domain, ... but when I try
to run a backup via
BackupExec, I get "No tape loaded". 

What did I miss ?

Did I miss somethink with the number of slots to define in BackupExec ?

Thanks
