I have a Office365 account with out own domain (a.com) and we have added a second domain (b.com) Both domains receives mail just fine.
How do I let the users choose which domain they should send from?
I want the user to be able to choose the "From" address when they send an e-mail message.
I have found a lot of how-to's but they all require the setup of additional accouints which in my view seems overly complex.
Any suggestions are most welcome!
