Usernames and other information associated with archived messages are imported to Retain’s Address Book the first time Retain archives a given user’s message data.
By default, these users can then authenticate to Retain using their messaging system credentials. For example, GroupWise users authenticate using SOAP or GroupWise LDAP, Exchange users authenticate using Active Directory credentials.
The first time they authenticate they are added to the list of Retain User Accounts, explained next.
NOTE:You can prevent users from logging in by using the Account Management Panel,
