I have 365 family subscription. I already have an email with a personal domain registered under the 365 account. I'm looking for the most efficient way to have MS host another (different) domain for another email address. From what I've been able to find, I can only have a single domain under a 365 account (although each 365 user can have an address on that domain). Is this correct?
Also, assuming that is true, it appears that the best way for me to have MS host an additional custom domain email is to add an Exchange online (plan 1) account for a single user. Does that sound like a correct solution? I assume this exchange account will act as a separate account from 365. Should I expect any difficulties when adding that exchange hosted, custom domain email address on outlook desktop under the 365 account?
Thanks for any thoughts
