How to transfer ownership of a microsoft hosted exhange server to another OVH account

I created and setup a Hosted Exchange for a customer to handle their contact email.

As I'm closing my activity, they found a new service provider. I need to pass over the ownership of the Hosted Exchange to their OVH account, but I'm a bit lost about the process.

The main goal is for them to not lose their email history over this exchange.

I could not find the answer in the documentation, but I may have missed something.

Thanks !
