You can view and change the properties of users who have previously been added to the Messaging system.
You can change a user name or extension without disrupting mailing lists. For example, if Jane Doe is on a mailing list and her name is changed to Jane Smith, Messaging automatically updates the list. A unique, system-generated user ID, and not the name or extension, links the user mailbox to lists and personal directories. You cannot access this system-generated ID.
You can also change user properties from the User Management Web page. However, this page does not have filters that assist you in locating a specific user.
For more information, see User Management > Properties field descriptions.
