We have a multi tenant Exchange 2010 SP2 system, we're hosting multiple clients, each client has its down domain. For example: client1 -> domain1.com & client2 -> domain2.com
Currently each client access OWA via our main domain: https://exchange.mycompany.com/owa
Each customer can configure his Outlook using our mail domain: exchange.mycompany.com
or using its own domain mail.domain1.com or mail.domain2.com.
One of my customers told me that he is getting certificate warnings from Outlook, he has his domain configured as exchange server: mail.domain1.com and the warnings are coming about his domain.
Our main domain has an SSL certificate installed, I can see it's working in the Exchange Console and also our IIS OWA is protected.
How can I install a separate SSL certificate for each customer? I have bough a wildcard SSL for him *.domain1.com and I want to use it so he will stop receiving this alerts.
