Yeah thinking the same. Microsoft 365 most likely the best switch for me. With 2 users and my custom domain, for cheaper might as well get 1TB cloud storage and Office as well.
I don't understand why they do this. Microsoft used to have a service called Windows Live Domains that used your normal TXT-record validation and killed it off in 2014; the shift to requiring GoDaddy be your registrar for outlook.com premium just baffles me.
