    Hi Chris (Riley),

    Thanks for your support.  We have found out the cause of my Exchange Transaction Logs not pruning:

    Exchange Transaction Logs only get pruned if both the Transaction Logs AND the Storage Group databases are backed up under a SINGLE BACKUP JOB.

    My backup strategy was:

    System Backup: One Backup Job running a full backup of C: (System Drive) once a week.

    Data Backup: One Backup Job running a backup of D: (Data Drive) daily - Weekly Scheduled Base followed by Daily Incrementals.

    It so happened that following advise to hold Logs and Database on separate volumes, my Transaction Logs were located on the C: drive and got backed up via the first Job and my Storage Group databases were located on the D: drive and got backed up daily.  As both objects were not backed up under a single job, the logs were not pruned.

    Thanks again for your help in this matter.  Hopefully this discussion will help others out.  I think it would be good also to make the explicit point about "both TLogs and Storage Groups under a single job" in the knowledge base.

    Kind Regards,

    Chris.
