Messaging databases work independently of each other under the direction of a set of software and hardware processes. These processes coordinate the files, databases, and system hardware. Since databases are handled separately, one database may contain information that conflicts with another database. For example, if a user is deleted from the Messaging database, other databases may still contain messages addressed to that user or mailing lists that include the name of the deleted user.
Audits can reconcile such conflicts among databases to check for inconsistencies and when possible, update the information in databases to correct the Messaging problems. For example, audits delete all references to a deleted user, which includes deleting the name of the user from mailing lists and canceling message deliveries to that user. Audits run automatically or can be performed by the administrator when required.
