Installation of Exchange 2016-Learning How to create new mailbox database

You might skip this section if you wish to keep the default database, which may be found under C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\. as the name is long and is going to be time consuming in the future (entering the long name),therefore, I prefer to create a new database and then delete default one.


I have made three partitions on my Exchange server, as I like to segregate Log and database disk and going to have a backup disk to clean up log files.


Name Drive Size and format
EXDB D: 10 GB, Allocation unit size 64K
EXLOG E: 5GB, Allocation unit size 64K
EXBACKUP F: 7GB, default allocation unit size
