Configure NGINX with Exchange 2010, 2013 and 2016 (including RPC / Outlook Anywhere access)

I have seen many threads on the internet with people complaining about RPC and Exchange (getting Outlook Anywhere to work.)

I have also seen several configurations all of which did not work correctly for me.

My configuration should work for 2010, 2013 and 2016:

server {
listen 192.168.0.1:443 ssl;
server_name owa.myserver.com;
ssl_certificate /etc/nginx/ssl/cert.pem;
ssl_certificate_key /etc/nginx/ssl/key.key;
access_log /var/log/nginx/mydomain.access.log combined;
error_log /var/log/nginx/mydomain.error.log;
client_max_body_size 3G;
proxy_request_buffering off;
ssl_session_timeout 5m;
tcp_nodelay on;

more_set_input_headers 'Authorization: $http_authorization';
proxy_set_header Accept-Encoding "";
more_set_headers -s 401 'WWW-Authenticate: Basic realm="fqdnofyourexchangeserver"';
proxy_buffering off;
proxy_set_header Connection "Keep-Alive";

}

# redirect all http traffic to https
