Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello,
Who's the reseller you purchased this license from? Pro Plus is volume license, not retail license. If you only have 3 licenses, it doesn't sound like you were properly set up as volume license/contract. Then it means the reseller sold them via channel that violates Microsoft's licensing terms. You would need to ask for Office Home 2024, or Office Home & Business 2024, and you need to steer away from any license with the name Pro Plus, LTSC or Standard.
