As far as I can tell, there are only very very light duty management tools for outlook.com custom domains.

Create an account
Suspend an account
Delete an account

I don't see any way to reset the password, for instance.

Part of the reason we have company email is that if a person leaves, the company still has access to the emails which the leaving person received from and sent to customers.

Are there workarounds, or are more advanced management features on the way?
