Exchange Server 2010 SP1 Self-signed certificates back on the menu in EV 9.0.1
You may have noticed the absence in the EV 9.0.1 release notes about Exchange Server 2010 SP1 self-signed certificates blocking the EV OWA extensions. Well that's because we are now able to support self-signed certificates. Therefore once you have installed or upgraded to the EV 9.01 OWA extensions there is no need to disable SSL for Exchange Web Services.
