Question

I recently purchased a domain name and need it defederated from Microsoft

randy 0

I recently purchased a domain name that the previous owner had connected to Microsoft. Godaddy is telling me that I need to contact you to defederate the domain name so I can use it.

Yeah 6 hours on hold is brutal, sorry you're dealing with that. Moving from GoDaddy to Microsoft doesn't automatically bring your old emails with you - that's a separate migration step that needs to happen.

When you defederate and move to a direct Microsoft tenant, you're basically starting fresh unless you specifically migrate the mailbox data. The emails are still sitting in the old GoDaddy-managed tenant and won't just appear in your new one.

You've got a couple options here. If the old tenant is still accessible through GoDaddy, you can export the mailboxes to PST files and then import them into the new tenant. That's the manual route but it works for smaller setups.

Better option is using Microsoft's migration tools to pull the data directly from the old tenant to the new one. You'll need admin access to both tenants to set that up though.

The defederation guide covers the transition process but doesn't get into the mailbox migration piece: https://mstack360.com/break-free-from-godaddy-defederate-to-microsoft-365-the-smart-way/

Honestly this is where things get tricky because you're dealing with both a defederation and a data migration. How many users are we talking about? That'll change the approach. And do you still have any access to the old GoDaddy tenant or is that completely locked?

Yeah this is a pretty common issue when buying domains that were previously used with Microsoft 365. The domain is still tied to the previous owner's tenant and GoDaddy can't do anything about it on their end.

Good news is you don't need a full migration or anything complex here. You just need Microsoft to defederate the domain from the old tenant so you can use it fresh. We actually put together a complete guide and video that walks through exactly this scenario.

Check out the FAQ here: https://mstack360.com/godaddy-de-federation-from-microsoft-365-your-complete-faq-guide/

And if you want the full walkthrough, the video covers the entire process: https://youtu.be/K7hIjTW-_Tc

Basically you'll need to prove domain ownership to Microsoft (which you already have through GoDaddy) and they'll disconnect it from the previous owner's tenant. Usually takes a few days once you submit the request.

Dear @randy,

Thank you for reaching out to the Microsoft Q&A forum. I am happy to assist you.

To better understand your situation and provide the correct guidance, may I kindly ask for a few additional details about the domain you recently purchased? This information will help determine why the domain is still associated with a previous Microsoft 365 tenant and what steps are required to release it.

Could you please confirm the following:

Has the domain already been fully transferred to your registrar account (GoDaddy) so that you are now the verified owner?
What exact error message or code do you receive when you try to add the domain to Microsoft 365 or your hosting service?
Did GoDaddy specifically inform you that the domain is still connected to a previous Microsoft 365 tenant and must be defederated? If so, could you share the exact wording of their message?
When did you complete the domain purchase?

Providing these details will enable me to offer the most accurate next steps and, if necessary, route your request to the appropriate team for further assistance. Looking forward to your response so we can assist you further!

I need you to defederate the domain name from Microsoft so that I can use my existing godaddy hosting account.
