Question: I want to use my own domain with my Microsoft 365 Family plan, but there is no way I am transferring it to GoDaddy. Is there way way around this “requirement” or am I stuck?

Answer: 
This related Reddit discussion indicates that it's possible and working at the time. It involves pretending to go to GoDaddy, and then capturing key values from the outlink for manual DNS updating.

> 2. Click the option to buy a new domain with GoDaddy, and a new window opens
> 3. Copy the URL of the new window that opens, it should look like this:

The answer is then : Not possible at the moment.
I have no information if this will change in the future.
