Can I purchase certificates for two domains
We are ready for the re-branding of our company. Currently our mobiles, devices and OWA users have access of current domain. OWA and smart phones have good working. We installed retail cert to make them all working without extra handling.
Originally, the new domain name was supposed to including a new AD domain for bigger projects.
It cut way back, and to cover the "re branded" new domain we are now going for additional DNS registration and external DNS hosting. For the new domain name, I have put in the DNS information and it correctly resolves the OWA site, but, it complains for certificate because installed cert doesn't match the new domain name.
Can I purchase a certificate with the name of new domain install it on existing Exchange and permit users to accessing either domain name?
