Is your feature request related to a problem? Please describe.
I set up an Exchange server for myself and my family privately. And I have all my web applications running through the Proxy Manager. Unfortunately, it is currently failing on the Exchange server, which I want to retrieve via Outlook Desktop. I guess missing NTLM support here.

Describe the solution you'd like
I expect an implementation of NTLM to connect the Outlook clients.

Describe alternatives you've considered
I am currently using the Caddy reverse proxy for the Exchange. I had to book an extra IP for this at the moment.

Thank you! :)
