How can i transfer all my microsoft account data to another one?

This obey for security reasons. As I'm not a Microsoft employee, I can't give you a more exact reason.

But sadly, that request can't be processed by them.

I'm sorry to say, but it is not possible to transfer any kind of content between Microsoft accounts.

How do I transfer my Xbox one gaming data and purchases from one Microsoft account to another Microsoft account

You cant. Nothing is transferrable between accounts

The Xbox account and the Microsoft account are basically one in the same. You cannot seperate them. All of the Xbox purchases and data are forever tied to the Microsoft account and nothing can be transferred to another account.

Just wow. Since I can't modify the original birthday all I can do is to create another account? I don't have words to explain how totally dumb is this.

If I create another account, is there a remote possibility to transfer all game data (savegames, achievements...) on the new one? I guess not...
