I am opening this question just to get a simplified steps which i need to work on.
I have 4 domains in the forest : NA-EUR-PAC-JPN
All except NA have got a SAN certificate for Exchange with the entry for : Autodiscover.Domain.com
In addition to that, each domain has their own webmail URL Like:
however except eur, all domains are using webmail.domain.com for webmail
Having said that...
on the internal DNS server we have a entry for autodiscover in domain.com which is pointed to a CAS box in NA.domain.com , however we do not have any entry for autodiscover in the external DNS zone. Considering that we still have sometime to upgrade our certs to SAN in NA.
I believe creating an entry in the external DNS for autodiscover which inturn will point to : webmail.domain.com/autodiscover/autodiscover.xml , which is also set as internal URI for autodiscover for the domain, can resolve security cert warning issue.
I am not sure if i have put the description in correct or in more descriptive manner...
But i wanted to knwo what can i do to get rid of security cert errors.
Please do not provide me the ref. links.
I need suggestions on steps which i need to carry out in my environment.
I will try my best to explain the situation again if required....
