The customers are happily using o365 email and there is no problem. How ever, what can we do so that at the sharePoint address or at the Skype Meeting link the onmicrosoft.com address wouldn't appear at all? They want to see only their own domain name there.
Further more, at one of our customers the initial o365 domain name (xxx.onmicrosoft.com) has a spelling error (should be xxy.onmicrosoft.com) and they don't like that since it shows up for example at Skype Meeting link.
This a a cosmetic problem.
What can we do?
