Me too. Just why?
I just went through a hellish Microsoft experience _trying_ to get Office 365 working on a Windows laptop. Got stuck in a fail loop: Create account -> Email already used. Login. -> Cannot login, account (email) does not exist. -> Create account. DO FOREVER.
The crazy thing is on Microsoft's own support (term used very generously) forums there are multiple threads with many pages on this very same issue. Imagine, I want to pay you for your product, but your rats nest of services is such a hot mess that it's nearly impossible. Unbelievable!
Converted the laptop to Linux dev box. Doing project using Pages and Keynote on my Mac.
