Says you get 3 submission attempts, but doesn't say how many attempts you've made. It doesn't say why you were rejected, just that you were. Microsoft Support's phone lines literally hear the word "Office" and say that all support for office is handled online, give you the URL, and hang up on you. And they black list your phone number for the day: any calls after that go straight to a canned message and immediate hang-up, no alternative available.
Multiple people from MS support have called me back over the month I've been at this, and each of them says, in summary, 1. I can't help you 2. Call this number 3. Give another number like the above that does not actually help.
