To this day I can't create an e-mail account on outlook.com with my full name as local part because Microsoft has a profanity filter and my lastname (that is my username here) contains a forbidden word "nude". Even though I was using the French version where "nude" isn't even a word here.

The worst part is that Outlook only told me that the full email address was "invalid", and that's by trying every frigging combination that I figured out that the "nude" part was the problem. If I were to remove only the letter "u", everything goes fine and the address is created. But who wants to have an address with a butchered lastname that would just create more confusion when spelling it.

I tried to contact Microsoft support by chat or forum, but most of the people either didn't understand or replied they couldn't bypass this profanity filter.
