What limitation applies to High Volume Community users regarding record sharing?

High Volume Community users have specific limitations when it comes to record sharing, particularly regarding their ability to manually share records. This limitation means that even though these users may own records, they do not have the capability to share them manually. This design aspect of Salesforce Community Cloud is essential to maintaining streamlined permissions and access control within community environments, especially given the large number of users typically associated with high volume scenarios.

By restricting manual sharing, Salesforce simplifies the sharing model for High Volume Community users, which is necessary to reduce complexity and ensure that the security of the data is maintained. This limitation helps prevent potential data access issues that could arise if many users were able to modify sharing settings on their own. As a result, High Volume Community users mainly operate under predefined sharing rules and organization-wide defaults rather than having fine-grained control over sharing individual records.
