2003 mailbox stores and public folder stores, make sure you 
maintain the following minimum permissions:

Folder Contents, and Read
•	Creator Owner   None
•	Server Operators group   Modify, Read and Execute, 
List Folder Contents, Read, and Write

organization including permission
 
2)Exchange Admin – Manage everything within the 
organization except org permission.
 
3)Exchange view only administrator – read only 
administrative access to Exchange organization
