I have a working Office 365 setup. The only domain setup is mydomain.com.br and everything is working as expected. Now, I have been asked to add mydomain.br domain (without .com) as an additional valid domain for sending/receiving e-mail. My expectation is to allow users to continue sending/receiving e-mail through mydomain.com.br as usual, but in addition, to allow sending/receiving through mydomain.br.
1) Is this supported by Office 365?
2) If so...what would we be the steps for achieving this? I've already purchased the domain
