User ID Resolution

This User ID Resolution menu item changes the method used for User ID restitution. See Resolve User ID Conflicts for the processes to resolve conflicts.

The system uses the Microsoft Exchange LegacyDN as a unique user identifier when processing mail. When moving users between Administrative Groups or Exchange Organizations the Exchange Legacy DN may change. To ensure that retained mail remains associated with a user as the LegacyDN changes, the SyncManager checks for multiple instances of the same primary email address on each directory sync. If multiple instances are found, a "User ID conflict" is identified and reported. You can configure the system to handle these conflicts in a variety of ways. In many cases, the multiple instances of the primary address refer to the same user, and you "resolve" the conflict so that all the mail for the user is stored together in the system.

• These four methods are available to configure, on a system level, how User ID conflicts should be handled:
• Manual: Each User ID conflict must be addressed manually by an administrator through the Admin Console. This is the default setting. See Resolve User ID Conflicts Manually for more information.
• Primary Email: All multiple instances of a primary email address are presumed to be the same end user, and all mail is associated with that user automatically without administrator intervention.
• All Aliases: If all aliases in the mailbox of the first instance of the primary email address are present in the second, the primary email addresses are presumed to be the same user, and the conflict is resolved automatically. The second may have additional aliases as well, but each of the primary aliases must appear. If only some or most of the primary ones are present, the action fails and an administrator must address the conflict manually in the Admin Console.
• Active Directory Attribute: Choose a custom or default attribute from the ones synced from Active Directory. If the attribute values match, the primary email addresses are presumed to be the same user, and the conflict is resolved automatically. Some examples might be Employee Number, User ID, phone number, or cell number.

Configure the system-wide method for resolving user ID conflicts:

1. From the AMS Admin Console, click System Settings.
2. Click User ID Resolution.
3. In the User Resolution Type field, select the resolution method from the drop-down list.

If you selected the Active Directory Attribute method, select the attribute from the Active Directory Attribute drop-down list.
