Exchange Domains

Ok so have an exchange with 10 accepted domains, reason for this is that we are a company merged with others... but i have a certificate that has one of the 10 domains on it, and works great with autodiscover etc, so i want to know if there is a way to add multiple autodiscover's in exchange and\or if i need a new certificate with all those domains on it for th autodiscover to work for each domain?

Then outlook anywhere, doesnt work anywhere :( i have my OWA working fine, but just doesnt connect via http in outlook, any ideas?

You can do a DNS Record to switch Autodiscover to your Primary domain. then you only need one certificate.

No, redirect to your primary domain. for owa you also should use the primary domain. it works for me.

Elmar KoschkaSenior System EngineerCommented:
on the domains you set a _tcp record with service _autodiscover to your right mail server (for example: your owa server)
autodiscover

Hi there,

just need to check with you, under the reverse lookup zones, ive got PTR records to all the domains, do i need anything else? i just cant seem to get this right...

Elmar KoschkaSenior System EngineerCommented:
you dont need a ptr for all domains. only for the domain of your mailserver ...

GNMareeAuthor Commented:
and any A hosts or CName under the domain?

Elmar KoschkaSenior System EngineerCommented:
i think you set the autodiscover for your mailserver on all domains, then a mx record on all domains to your exchange server. for exchange you need not more. only on the one right domain of your exchange you must have a mx and host record..
