A Sales user is trying to manage Campaign Members for an upcoming networking event. The user can view the Campaign, but add new Campaign Members or update Member statuses. How can an administrator…

While a permission set could grant broader edit permissions, the specific 'Marketing User' checkbox is the primary control for full Campaign Member management capabilities.

While access to Leads and Contacts is needed to add them as members, the inability to manage existing Campaign Members or update their statuses points to a missing 'Marketing User' permission, not just source record access.

The 'Marketing User' checkbox on a user's record is a foundational permission required for managing Campaign Members, including adding new members and updating their statuses, even if the user has read access to the Campaign record itself.

Using Data Loader is a method for mass data manipulation and is not a troubleshooting step for a user's inability to perform actions in the Salesforce user interface.
