  1. Hi Ali, appreciate all the info you post, very helpful! For an NTFS mounted volume, I created a new volume and pointed it to the mount point path which is located C (for example C:\MDB01\Database), however exchange placed the database and log file in the default Microsoft location in Program Files. How do you recommend populating with the correct syntax to place the db/log files in the ntfs mount?
