Which of the following is NOT a feature available for partner users managing leads?

The correct answer is C, "Import case comments," because this action is not relevant to partner users managing leads within Salesforce. Partner users typically focus on lead management functionalities such as creating, editing, transferring, and updating leads, which are essential for their interactions and collaboration within the CRM system.

The features that are available for partner users, like mass updating leads, transferring leads to other users, and creating and editing leads, directly support their role in managing and nurturing potential sales opportunities. Importing case comments, however, pertains to the handling of support or service-related cases, which is outside the scope of lead management. This distinction underscores the specific functionalities designed for partner users in Salesforce, emphasizing their focus on lead rather than support activities.
