This is SBS 2008. Our self-signed certificate expired yesterday. I have used the 'Set up your internet address' wizard in the SBS console. I can see the new certificate is there, and it expires in July 2016.
My problem is that the client pc's dont seem to trust it. When anyone opens Outlook they get a certificate error stating that the certificate was issued by a company we have not chosen to trust. When I look at the certificate, it is issued to remote.myexternaldomain.com and it is Issued by internaldomain-server-CA I've checked the expired certificate and it has the same information. So how do I fix this?
