Hi there,

i set up nginx for my customers to access their exchange servers (2003/2010) that are hosted by us.

OWA -> great, no problem

Android -> Ok as well (i saw a thread where someone had problem... i had nothing to do to have it work)

EWS (used by mac, mail program) -> not working, this is my problem
in fact the mac is trying to connect to https://mail.domain.com/ews/exchange.asmx but is looping asking user/password.
For debug purpose, when i try this url with a browser, bypassing nginx, i get a kind of xml file. Doing it going through nginx ask me user/password as a loop.

Be sure i spent all the afternoon searching related problem but found very few things but using another reverse proxy (!)
It seems this is the way EWS works that confuse nginx that is awaiting something instead of passing through.
Saw that in this thread : http://forum.nginx.org/read.php?2,236709,236724#msg-236724


I there obvious things i can try or do you need more informations ?

Many thanks for any help.


My config is quite simple :

server {
listen 443;
ssl on;
ssl_certificate ssl/mail.domain.com.crt;
ssl_certificate_key ssl/mail.domain.com.key;
ssl_prefer_server_ciphers on;
ssl_protocols TLSv1 SSLv3;
ssl_ciphers HIGH:!ADH:!MD5:@STRENGTH;
ssl_session_cache shared:TLSSL:16m;
ssl_session_timeout 5m;

server_name mail.domain.com;
access_log /var/log/domain.access.log;
error_log /var/log/domain.nginx_error.log debug;
location / {
proxy_pass https://192.168.1.1/;

Hi,

i'm still searching but found nothing that can help me.


As i have no reply, can you tell me if my question :

- is posted in the wrong section
- is asked in a bad way
- is too difficult :-)
- anything else


Thank you a lot

I ran in the same issue today.

The solution was to disable integrated windows authentication and enable basic authentication instead under Server/Virtual Directorys/EWS in Exchange Admin Panel.

Hi, i'm really ashamed, i totaly missed your reply and never found the solution !

now when doing https://mail.domain.com/ews/exchange.asmx i can enter with password with no problem, great !

For the time being, i can not test on a mac but i'll try asap.

I hope this could help others...

Thanks a lot
