Migrate Exchange Online Plan 1 to godaddy to save money on the subscription.

I currently have about 15 email users on the Exchange Online Plan 1 with Microsoft. I would like the domains to be moved to GoDaddy from Namecheap. I want the existing emails to be set up with exchange through GoDaddy. I understand I will probably have to renew many domain names. I am trying to save money on the email plan. If you understand what I am talking about please send me a message. Don't contact me if you are looking for a quick buck and don't know what I am talking about. Thanks! Joe
