E-Mail autoconfiguration error

Hey, together, i want all my virtual servers to use the same domain for the e-mail configurtaion, because of ssl issues. So i changed the server entrie about the sevver/host. But lateri noticed that the autoconfig isn´t even working. using the Microsoft Remote Connectivity Analayzer showed me an error in line 1

Here is a link to the autodiscover.xml: https://juvo-design.de/Autodiscover/Autodiscover.xml

Does anyone know whats wrong and how to fix it? Till now i just edited the outlook part.

Greetings and thanks Helias10
