Exchange 2010 certificate issue after CA no longer support internal names

Last Modified: 2016-05-10

I have an Exchange 2010 environment where until yesterday was working fine but now the CA no longer supports internalname.local

I have re-issued the certificate which work fine externally for www.mail.domainname.com but local Outlook clients complaining that the mailservername.local isn't trusted which it isn't anymore

My AD is configured as domain.local and not companyname.com

Could do with this help resolving this. Any ideas?
