Last week, our self-made certificate expired on the Exchange server and "remote outlook" (RPC over HTTP) stopped working with an expired certificate error. However, the Outlook Web Access via browser did work. On Wednesday evening I renewed the certificate and now none of it works. If I use the remote outlook it does not ask for authentication and opens Outlook but it will not connect to the Exchange server. If I use the web browser I get the error: Internet Explorer cannot display the web page. If I use the same URL without the "s" (just http://
) it connects but of course it is garbled due to my setting in IIS to use SSL. So it seems something regarding the SSL is not working correctly but I cannot figure out what that is. Right now our OWA is unusable. I have reset IIS but it did not help. Any ideas?
