What could prevent a user from accessing the mass transfer tool?

Accessing the mass transfer tool is directly linked to user permissions within the system. If a user lacks the required permissions, they will be unable to utilize the tool, regardless of other settings or configurations. Proper user permissions are essential to ensure that users can perform specific actions, such as mass transfers, which are often sensitive operations involving significant changes to data. These permissions are typically governed by the user's role within the organization and the associated profile or permission sets that grant access to certain functionalities.

In contrast, while incorrect IP settings, unassigned profile levels, and the absence of active campaigns can affect system usage or features available to users, they do not specifically prevent access to the mass transfer tool in the same direct manner as permission settings do. Therefore, having the correct user permissions is the cornerstone for enabling access to this tool.
