I have migrated from 2007 to 2013. I did a couple of test migrations and on the ones with domain member computers Outlook is giving a certificate warning. The certificate they are presented with is the default self signed certificate on the 2013 server. Even though I have added a trusted public certificate to Exchange and checked of to use With IIS.
I see that the default certificate is also checked of to use With IIS and it cant be removed in ECS. Shouldnt this be removed from IIS all together when adding a New certificate? And why does some Clients gets presented With the self signed and some With the Public? For instance owa is presented With the Public cert. Also and Outlook I tested from outside the domain.
