HI 

Check your bindings in  Default Web Site configuration
Remove the extra bindings if you see anything
Check if OWA is bound to the correct ports 

Thanks Sathish.

Done this already :(

Wondering if some could just post default settings.

Here you go 

Authentication depends upon your config (ssl offload, basic , NTLM etc...)

If its not working recreate the VD and see the results.

Hi All,

Just wondering if someone can help with owa, ecp binging and authorization details. My server was working perfectly and i installed remote desktop services on the same server and had to remove the role.

Once i did that OWA and ECP would not longer function, had a lot of searching however no real solution for the problem. Event logs are simililar for every service and here is one of them, had also removed and recreated the virtual directories, nothing worked, however outlook is working fine.

WebHost failed to process a request.

Nop This didn't help either, wondering what the problem is.

This has now been resolved. I thought i would write for anyone that might face the same issue.

In my case the exchange backend  had a 443 binding, that was causing the issue. Removed that and  restarted iis, fixed straight away.
