The users that are included in your Messenger system are those users whose User objects are located in an eDirectory context listed in a scope profile or an LDAP profile. If you need to exclude specific users from your Messenger system even though their User objects fall within the scope of your Messenger system, you can do so.
If you want to maintain a list of excluded users, you can create a policy to govern the excluded users, as described in Creating a User Policy. On the General page of the Policy object, deselect Enable Novell Messenger Services. On the Used by page of the Policy object, list those users that you want to exclude from your Messenger system.
You can also edit the Novell Messenger General page of individual User objects and deselect Enable Novell Messenger Services for individual users.
