Hello,
Since there are new restrictions for SSL certificates and they no longer allow .local addresses I have removed myserver.domain.local address from the OWA SSL certificate and this has caused local Outlook Clients to have the error “The name on the security certificate is invalid or does not match the name of the site”.
We are currently running Server 2012 with Exchange 2013 and have not yet been able to figure out how to resolve this error message. In the past using exchange 2007 and 2010 when this has happened I used powershell commands to rename the virtual directories to an external URL that is also listed on the SSL certificate. In Exchange 2013 I cannot get these commands working and have settle to change the virtual directories through the exchange control panel. After these changed I have recycled application pool “MSExchangeAutodiscoverAppPool”. After these changes I still get the same certificate error and after researching this I have hit a wall. If anyone has any ideas or has ran into this please let me know.
