@jbostoen did you make sure it works without nginx in front? I spent a lot of time on this and it turned out to be an exchange issue that needed fixing.

adamjs83 · 2016-02-24T16:37:14Z

I finally got this working and posted the detailed instructions on my blog. http://blog.adamjoshuasmith.com/deploying-exchange-2016-behind-nginx-free/

@jbostoen I believe your issue is that you are using an Admin user account which will not work with Activesync. try creating a new user who is only in the Domain User group and test active sync with that mailbox. If it works, you know where your problem is.

Just stumbling back on this. Desktop Outlook is what I need to get working...
Thanks for the great write-up!

Martinvdm · 2018-07-06T19:14:11Z

I have tried this config from tigunov and from adamjs83 but both configs are not working with outlook anywhere and Exchange 2013 with RPC over HTTP. Nginx logging is generating 401 for RPC_IN_DATA and Outlook keeps asking for login credentials. Somebody know what i am doing wrong here?

enoch85 · 2019-06-15T21:31:52Z

This worked for me: https://gist.github.com/enoch85/573dac9005f0c8f1b826cc22e520e0ae

RPC doesn't work with the free version... the last time I tried to go down this hole it led me to that answer.

Did you ever find out what was causing your FolderSync issues? I get a 502 bad gateway.

Alex-JTI · 2020-12-09T10:17:44Z

RPC doesn't work with the free version...

I'm running Exchange 2010 with RPC over HTTP. All is working well including RPC and no 401 is generated.
The config is similar to https://gist.github.com/enoch85/573dac9005f0c8f1b826cc22e520e0ae with the only difference that I also pass 2 more headers:
proxy_set_header Authorization $http_authorization;
proxy_pass_header Authorization;

enoch85 · 2020-12-09T12:29:50Z

Thanks @Alex-JTI, it's now updated!

mamama1 · 2021-07-27T19:57:05Z

@Alex-JTI @enoch85 is this working with NTLM or with Basic authentication? I was thinking nginx free cannot handle NTLM...?!
Thanks!

Hello! I want to make a reverse proxy for MS Exchange using nginx with the spnego-http-auth-nginx-module module. How to make nginx check clients using certificates, and if they passed, then authorize them on MS Exchange using Kerberos. Clients must connect to MS Exchange via Activesync. Configuration example:

server {

server_name rp.blablabla.com;
listen 443 ssl;
ssl_certificate /etc/ssl/nginx/cert.pem;
ssl_certificate_key /etc/ssl/nginx/cert.pem;
ssl_session_timeout 5m;
client_max_body_size 2G;
ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
ssl_verify_client on;
ssl_verify_depth 5;
ssl_client_certificate /etc/ssl/nginx/cert.pem;

proxy_set_header Host $proxy_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

#keealive is only in 1.1 supported, default is 1.
proxy_http_version 1.1;

location ~* ^/Microsoft-Server-ActiveSync {
proxy_pass https://exchange.blablabla.local;
auth_gss on;
auth_gss_realm BLABLABLA.LOCAL;
auth_gss_keytab /etc/nginx/spnego.keytab;
auth_gss_service_name HTTP/rp-mail;
auth_gss_allow_basic_fallback off;
}
Maybe there is another way to implement
the connection of remote clients via Activesync with certificate verification, as it is implemented on the Microsoft Forefront Threat Management Gateway?

MakoWish · 2023-01-06T04:30:34Z

@Alex-JTI Thank you! Your solution worked for me. I made some slight modifications, because I am using it for Microsoft RemoteApp instead of Exchange, but same RPC over HTTP situation.

tomasenskede · 2023-05-29T18:37:02Z

I'm experiencing a similar problem... Is there anyone available who can offer me assistance?

I have configured Ngnix Reverse Proxy within my Docker on Proxmox. Within my network, I have Exchange 2016, and my users are accessing it remotely using Outlook, mobile ActiveSync, and OWA.

OWA is functioning correctly with my new setup, but ActiveSync and Outlook (RPC/MAPI over HTTP) are not working.

Is there a way to resolve this issue and make them function properly? I would greatly appreciate any tips or guidance. Thank you very much!

proxy_buffering off;
should fix the issue with RPC/MAPI over HTTP

tomasenskede · 2023-05-30T08:12:13Z

/etc/nginx/nginx.conf

is this correct? am I in the correct config?

Where should I add "proxy_buffering off;" ?

the certs, arnt present... do I have to generate these manually? I have generated certs in the GUI...
/etc/ssl/nginx/www.dmz.se.crt;
/etc/ssl/nginx/www.dmz.se.key;

Do not use nginx for Exchange, it's not work correctly, better use haproxy

I am using first version mostly, but for second one, change reqadd X-Forwarded-Proto:\ https
with
http-request set-header X-Forwarded-Proto https

About certs, I think you can use them, but you will have problems in clients, they will spam about security
I am always using Let Encrypt one

I so many times wasted on nginx, and it's not work correctly with active sync

Right now I have few servers with HAProxy and Exchane on backend, and it's no problems at all.

Thank for you reply, if I could get Nginx working with Exhange that would be my first choce.

do you have the site (www.contoso.com) setup in the Nginx GUI with SSL cert?
1.1) if so, can I use the same cert in the config above? (ever do Nginx store cert created with eht gui)
1.2) if not, hos do you create ssl certs?

MakoWish · 2023-05-31T14:26:57Z

I was not aware there is a GUI for Nginx.

I use NameCheap for my DNS, and I purchased my certificate through them. If you want your site/service to be trusted externally (outside your private network), you will need to purchase your own certificate.

Nginx Proxy Manager offers a user-friendly graphical interface for managing websites and Let's Encrypt certificates, and it performs exceptionally well. I previously relied on GoDaddy's certificates, but now I exclusively utilize Let's Encrypt certificates.

@MakoWish - thanks a lot!

When I add this to "Custom Nginx Configuration" I got ActiveSync working!!

POST /Microsoft-Server-ActiveSync/default.eas ... 200 - Success!!!

But, MAPI/RPC over HTTP results in HTTP 401-error

/autodiscover/autodiscover.xml ... 401
POST /mapi/nspi/ ... 401

Any idea on why this isnt working?
