Outlook 2007 can now use DNS SRV records to find the location of the Exchange Autodiscover Service
Hi Brad,
After I installed one single-name SSL certificate with common name e.g. "mail.contoso.com" on a CAS server, I start to see Outlook 2007 clients within the intranet receiving "security alert" saying "The name on the security certificate is invalid or does not match the name of the site". The Outlook 2007 clients are looking for e.g. "autodiscover.contoso.com" and "cas01.contoso.com". I want to avoid such security alerts. I understand the certificate that supports Subject Alternative Name is an option. But as you mentioned, it can be expensive for some customers. I want to know if there is any way to avoid such security alert for intranet Outlook client by using one single-name certificate installed on one web site (the Default Web Site) of the CAS server.
Thanks,
Adam
