I have a server which now has various public domains, the issue I have is I only have a 5 UCC certificate which covers only 1 domain (TEST.com) for example.
The issue I now have is when other external users are working remotely certain things dont work such as out of office, I understand this is because the autodiscovery service looks at the email domain and tries to connect to the sub domain (autodiscover.otherdomain.
com) for example.
I do understand that I could buy a really expensive cert with say 50 SANS but that is going to cost a bomb and also if any new domain is added I would have to buy or reinstall the certificate again.
What I need help with is from what MS say you can redirect all external users to point to the say address, see this link below.
The issue is I am not sure what I need to enter into each box within IIS, if anyone could point me in the right direction I would appreciate it.
