Exchange 2016 - OWA not working or redirecting from http

Question

Thursday, September 14, 2017 10:08 AM

Firstly about me - not bad with Exchange but a bit of a newbie with IIS

I setup an Exchange server and external domain, and it all worked great.
If I went to http://owa.domain.com  I would get a login, and it (I think) auto redirected to https://owa.domain.com

Sometime recently, and I don't know what caused it, http://owa.domain.com now gives:

(CHROME)

You don't have authorization to view this page.

HTTP ERROR 403

(IE)

The website declined to show this webpage
 
  HTTP 403 
     
Most likely causes:
•This website requires you to log in.
     
What you can try:
  

  Go back to the previous page.  
  

More information   More information  

this error (HTTP 403 Forbidden) means that Internet Explorer was able to connect to the website, but it does not have permission to view the webpage.
 

It's not the firewall as that is fully open for port 80, so I guess it's some misconfiguration in IIS. Any pointers?
many thanks

Hi

Go to IIS -> defaultwebsite -> OWA -> properties -> documents: re-added Default.htm, Default.asp, index.htm and iisstart.htm.

I did say I was a beginner with IIS but don't see a "properties" option in right click or any of the icons. Thanks for the answer and any clarification Raj....
