I've run into a bit of trouble with an Exchange 2013 installation. The server had issues with OWA which I thought where connected with certificates that might not be correctly configured. To fix this I used ECP to register a new, self-signed certificate from scratch. I somehow connected this to IIS (for ECP and OWA) and set it up to need SSL. Now I've run into the problem that whenever I try and open ECP I get an 403.4 error because the http-url forwards or is looking for the https version.
I didnt setup or install the environment so what I basically am looking for is a direction to reset certificates in Exchange back to defaults, so I can use ECP to try and fix everything again. Any suggestions are welcome :D.
