Microsoft email custom domain address but no free teams?

New Contributor
I have Marty@xyz.com it has a 365 licence and Teams... included in the licence

I have a second Microsoft mail account for frank@xyz.com (no 365 licence) just Microsoft mail @xyz.com domain

@xyz.com hosted by go daddy
Marty@xyz.com & 365 purchased through go daddy
Frank@xyz.com Microsoft mail purchased through go daddy (no 365 licence)

I am Marty and I can see frank as a member of the xyz.com organisation in teams when I’m logged in

But Frank can’t log into free teams or join...

Go daddy are telling me I need a 365 licence For frank

This doesn’t seem right since a free Microsoft account holder can access teams for free but (but because frank has a paid Microsoft mail account he can’t have free teams?)

Can someone help?

GoDaddy have their own flavor of O365 services, and the "generic" guidance doesn't apply, so best clarify this with their support.
