My business resells Microsoft Office 365 products (yeah, I know, but there are no FOSS systems with comparable feature sets for businesses...)

One problem we ran into a lot was that if a customer already had Office 365 through GoDaddy, we would have to basically delete their whole organization and manually import all users, emails, and settings from the GoDaddy managed O365 to ours. The reason for this is that when a company buys MS O365 products through them, GoDaddy sets it up as a Federated domain. This means that GoDaddy and GoDaddy alone gets to manage the MS O365 tenet, you cannot transfer it out, and if you cancel service with GoDaddy, they delete your account and all your data.

Then I found this guide: https://tminus365.com/defederating-godaddy-365/

I just used it to successfully de-federate my first GoDaddy account, retaining all my customer's emails, files, and Active Directory (ahem, Entra ID) information.

Screw you, GoDaddy!
