I have an exchange 2003 server with SP2. The root exchange object in EMS hasthe "Anonymous Logon" and "Everyone" account listed under the ACL. Can I remove both without impacting exchange? Do they really need to be in the list? I have googled for the information and searched the Microsoft website and had no luck. Anonymous= Allow -Create Public Folder,Createnamed properties in theinformation store, 2 Identical Special permissions= Allow - Read, Execute, Read Permissions, List Contents, Read Properties, List Object. Everyone = Allow -Create Public Folder,Createnamed properties in theinformation store, 2 Identical Special permissions= Allow - Read, Execute, Read Permissions, List Contents, Read Properties, List Object. Thanks in advance for your responses.
