Found it after 18 hours ;-) This was a very helpful link:
https://support.microsoft.com/en-us/help/3211279/outlook-2016-implementation-of-autodiscover
EDIT --> THE SOLUTION!!! / it only works when login with the tenant.. user@xyz.onmicrosoft.com or when you changed primary email to user@<domain>.<tld.> it is till working. -------> AND!!! Made some registry tweaks see below
not sure what exactly the proper key is... 16.0 stands for Outlook 2016 - funny is when I delete the keys.. and even reconfigure mailbox no autodiscovery popups are comming. Condition is that I'm logged in with the Microsoft O365 tennant which is connected to the Mailbox.

I don't want to be rude or something like that.. I already spent 15 hours on this issue.. still no solution. And got only things told that I already did and wrote in my post.
I have a business running and I need professional <timesaving> support. Is this an official Microsoft Support Forum. Or have I the wrong expectations?
