Outlook's autodiscover process, which is great, first tries to send a POST request to ourdomain.com/autodiscover/autodiscover.xml but ourdomain.com is actually our website - we use office365 as our exchange server. Normally, this would only result in a bunch of 404 errors that we could gladly ignore. Unfortunately, our web platform is configured to redirect 404 errors to the internal search engine, so when this request is made, it attempts to serve ourdomain.com/search?autodiscover+autodiscover+xml which adds an unwanted burden to our web server.
How can we get outlook to skip this step in the autodiscover process and move on to autodiscover.outlook.com? I know I can deny any request to the location autodiscover, but I was hoping there was a more graceful way of handling this.
