Hello,
i’m a bit stuck setting up my HAProxy reverse proxe in combination with Exchange.
I have several webservers but only 1 public IP so i opted for HAProxy as reverse Proxy.
All my websites work except for the Exchange 2019 - Outlook connection.
When i fire up outlook from an external connection i continuously get prompted for a password.
Internally (or when i configure my hosts file to point to the reverse-proxy) everything works great.
I’m a bit at a loss what the problem could be.
I’ve stripped my config file to remove my public address etc. and i removed the other sites/acl’s.
Can you please take a look at my config and tell me how i f-ed up? 
Here is my cfg file: https://pastebin.com/Gk56CmCn
Thanks in advance for any advise
