I didn't follow the part where you couldn't give them a Microsoft id for a commercial office 365 license. Presumably you were giving them your personal Microsoft id used with office 365 home at home for your own personal non commercial use? Why did you not just give them the id for the commercial office license your company must have to use office for commercial purposes? It's understandable that one of the differences with the greatly discounted non commercial use office home license is lesser support than the more expensive commercial license is entitled to. Support is expensive.
