Q: I already own a domain that's registered with a provider other than GoDaddy. Can I set up a personalized email address in Outlook.com?
A: At the moment, we only support connecting domains managed by GoDaddy with Outlook.com.
Maybe that only applies to "Microsoft 365 Family or Microsoft 365 Personal" and not their business offering? They have a basic business offering for $5/mo, but it doesn't include the Office apps (just the online versions).
The non-GoDaddy workaround from the adjacent reddit link works fine, not sure why the sibling comments have been downvoted so hard.
The reply to that about the workarounds disabling spf is wrong, at least for the adjacent reddit link. It includes relevant spf records and they appear to work fine.
I’ve been hosting my custom domain on the personal office 365 / outlook.com using these workarounds for a couple of weeks now and so far it has been working just fine.
Ideally dmarc and dkim would be supported, but it’s worth noting that it appear that neither of those are supported by the personal office 365 / outlook.com plan even with GoDaddy.

EDIT: It looks like non-GoDaddy is for business/enterprise plans: https://docs.microsoft.com/en-us/microsoft-365/admin/setup/a...
