Site runs fine locally but when it is published in the server, Web app shows "Service Unavailable- HTTP Error 503. The service is unavailable".

I check the WCF service. It is available and it is running in the IIS.

I checked the basic binding settings in the IIS, it gives error for authentication :"The user name or password is incorrect. (Exception from HRESULT: 0x8007052E)"

and for authorization it says: "The credentials used to access the specified physical path are invalid. Verify the credentials and test these settings again."

I don't get it.. please help

    most likely the pool account password is wrong, or the pool account does not have access to application folder

    The solution is the SSL certificate seemed to have come off of the Exchange Backend website. I selected the Exchange certificate on the IIS site, and it started working.
