You can move the log files and database files to any folder that you want to create. When you move logs and database files, you may want to create the ExchsrvrMdbdata file structure for consistency reasons, but you are not obligated to do so.
You must grant the following default permissions to the new Mdbdata folder that contains the log files and database files:
Note Only assign permissions to the Server Operators group if the Exchange server is a domain controller. Otherwise, assign permissions to the Power Users group. Only domain controllers should have permissions to the built-in Server Operators group. Stand-alone and member servers should have permissions to the built-in Power Users group.
You may also have to grant the following permissions to the root drive that contains the new Mdbdata folder:

Instead, you could use the C:Subfolder path. In an organization that uses Exchange 2003 and Exchange 2007, the 2007 management tools will flag database or log files that are the root of a drive as an error.
