We are running SBS2008 with server1.companyname.local domain name. We are using GoDaddy SSL security certificate that covers the names: server1.companyname.local, remote.companyname.com, autodiscover.companyname.com. Since GoDaddy SSL certificate did not support .local domain anymore. I got Event ID 12014 error on the server related to "Microsoft Exchange could not find a certificate that contains the domain name server1.companyname.local in the personal store of the local computer." So far internal and external users have no problems sending and receiving emails.
I tried to fix the Event ID 12014 using Exchange Management Shell by typing "Enable-ExchangeCertificate -Thumbprint xx...xx -Services "SMTP" where xx...xx is the current thumbprint shown linked to the name server1.companyname.local. After typing this command, it asks if I want to overwrite the existing SMTP service xx...xx Thumbprint issued by GoDaddy.
My questions are:
1. Can I ignore the Event ID 12014?
2. If I overwrite the existing SMTP GoDaddy Thumbprint, will it affect the external users with mobile devices such as iPhone connected to the SBS2008? My local users' outlook is connected to server1.companyname.local.
