"I am calling from Microsoft" calls were bad enough. Now they will know some details to a past case and sound slightly more legit.
The rep was very helpful, but a bit puzzled that I wanted him to read me my ticket title. He seemed to think him knowing my name should be sufficient verification.
Note: I can never understand Microsoft's names for different levels of the same product. It might not be called a business account, maybe professional or pro or small business or something.
By the way Microsoft has absolutely terrible azure support. If you have a legitimate issue and you dont have a dedicated support consultant good luck to you.
