Which licenses are specifically designed to support External Account Relationships?

The selected answer highlights the licenses specifically designed to support External Account Relationships. Both Partner Community and Customer Community Plus licenses are tailored to facilitate interaction and engagement with external users, such as partners and customers.

Partner Community licenses are intended for partners who need access to Salesforce to manage sales processes, collaborate with internal teams, and track performance metrics. They are equipped with features that enhance the partner experience and allow for deeper integration with the organization.

Customer Community Plus licenses, on the other hand, are aimed at providing customers with a broader range of capabilities within the Salesforce platform. These licenses offer deeper access compared to standard customer community licenses, enabling customers to engage with the company's services and resources more effectively.

This specific focus on external relationships distinguishes these licenses as ideal for situations where communication, collaboration, and data sharing between the organization and outside entities are crucial. Other license types, such as those mentioned in the remaining choices, do not have the same targeted features for managing external relationships.
