Which type of support should be used when a customer's issue cannot be resolved remotely?

Desktop support is the most appropriate type of support to utilize when a customer's issue cannot be resolved remotely. This type of support typically involves an IT technician physically visiting the customer’s location to diagnose and resolve issues that cannot be handled through remote assistance.

In scenarios where problems require hands-on intervention, such as hardware malfunctions, installation of software, or intricate configurations, desktop support provides the necessary expertise in person. The nature of certain technical issues often dictates that a technician must be present to effectively address the problem, making desktop support essential in these situations.

Other support types, such as electronic support, self-service support, and automated remediation, primarily focus on resolving issues through remote communication and tools, tutorials, or automated systems, which may not be sufficient for resolving complex problems requiring physical interaction.
