Which method is NOT a way Internal Directories can be populated?

The method identified as not applicable for populating Internal Directories is outbound. Internal Directories can be populated through various methods that involve bringing information into the directory system. Manual Import allows users to take existing data from external files and insert it into the directory, facilitating bulk updates or integrations. Manual Creation involves individually adding entries to the directory, which can be useful for unique or specific cases.

On the other hand, outbound implies sending data away from the Internal Directory, rather than adding to it. Hence, it does not contribute to the population of the directory itself. Directory Connector, similar to Manual Import, typically involves synchronization of user data from an external system or database into the directory, reinforcing the idea that populated entries need to come from an external or manual source rather than being "outbound." This distinction clarifies why outbound is not a valid method for directory population.
