Sigh, I'm in the same boat. Previously, the supported procedure REQUIRED Godaddy for your registrar. Recently MS announced that they are no longer going to offer new custom domains starting in 2023. Apparently you can set one up prior to the cutoff date and they will let you use the custom domain. Personally, I don't want to use Godaddy and I don't want to be in some kind of unsupported position eventually so my plan is to go with a different host someday.

I have a 365 family subscription and I own a domain. I want to create an email in outlook using my domain but I can’t find out how to do so. Do I have to have a business account?

I had the same problem so I googled and found this in Microsoft's help pages:

You can add multiple custom domains in all Office 365 subscriptions[...]

This help article looks as if it were possible but they only talk about the business versions and Office 365 Home isnt mentioned with a single word - so I continued my research, even contacted Microsoft - they had no idea, but then I finally found this post:

yesterday I called MS Support and the support engineer was discussing in the background with a colleague. Then he said that it's possible to use own domain with O365 Home... I just had to create a new account with my personal email adres/domain... after that I could order O365 and configure it with my own DNS domain name. Then after changing MX records with my hosting provider this would work for me.

anyway... I tried this anyway... I created a new account with my personal domain... then I ordered Office365Home hooked up to my paypal account....but in the end... no options for me to configure this. So I called back.... I got the same engineer... but then he said.. sorry, I don't have enough technical expertise, cause I'm a sales guy.... strange, because I tried to get tech help... The guy gave me a phonenumber to local (Belgium) Microsoft Tech support.... so I called the number. Then I got first or second line tech support on the line, so I expained the situation and the proposed option from his colleague. But I got a negative response.

No, sir, O365 Home does not allow you to use your own domain... why should it, there are not so many families using their own DNS domain, sir...

DUHH !!! What ? I don't understand their response... I times like this... people make their own family website... use a personal domain.... so I believe this is really a stupid reaction from a Microsoft Tech guy. Probably he has his own domain at home ;-) The only option is to choose for O365 Small Business and pay a lot more, because you need to pay for every user... every family member... so that would cost me at least 200€-250€ yearly.... please get serious ! so I give up.... Also Google Apps only has a business solution... also around 200€ yearly. Office365 Home... useless -> go for Office365 SMB... 2expensive ! I'll try again when Microsoft grows up and gets serious.

After all I don't think it is possible, I also found some forum posts and comments in blogs and they all say it isn't possible.

As of January 2020, this is now possible with a subscription to Microsoft 365 Personal or Family Edition (formerly Office 365), but according to Microsoft you are required to purchase your domains with (or transfer them to) GoDaddy. I have found sources that claim this is possible with other domain registrars, with some users reporting success, but Microsoft maintain that this is only possible via GoDaddy.
