Somehow you need to log the result of what redirectionUrl is. You will get this error when your redirectionUrl doesn't match the URI you've specified (i.e. your autodiscover validation callback returns FALSE). Certainly the redirectionUrl URI is not what you think it is. If you are using SSL - you need to handle the redirect validation callback.

Since you cannot debug the application, perhaps you could send an email to yourself, log to a shared DB or file, or perhaps use the app event log (throwing an application exception).

Note: The first error does tell you the autodiscover URI is https://autodiscover.colpatria.com/autodiscover/autodiscover.xml. Should this replace the existing string https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml?
