Hi all

We are hosting an Exchange 2010 server for a client and now this client has contacted us and wants to move all of his 400 email-users over to us. Currently, this client only has one domain hosted on the server and is using a UC SSL certificate and this is working just fine. My question is what do we do when he wants to move 8 more domains over? Is it possible for us to install 1 certificate per domain on the server, without having a dedicated IP per SSL?

Any help will be highly appreciated.

Thanks.

Thomas

I believe you might be able to use something like a wild card certificate....

 

*.com

I guess it depends if they are sub domains or not?

 

No. These are "regular" domains and not sub-domains.
I have read about the possibility of using host headers and 1 wildcard certificate, but I would actually prefer, if possible, to have the certificate report the actual domain it was used on, instead of using host headers and redirecting the domains.

 

As far as I know, it is only possible to have one common name per certificate and if you use UC certificates, you can then add sudomains and internal domain names and IP's

Roger that

 

If you are hosting there domain then I would hope that you know that you can have oudles of sub domains and one primary domain.

You then only need a SAN SSL for the primary domain to work with Exchange 2010 for example I could have the following:

craigie.com (Primary)
craigie.co.uk
craigie.biz
craigie.org

You would still recieve emails from the other domains but when you reply, it would come from craigie.com unless otherwise specified on the individuals malibox policy.

Also, end users would go to https://mail.craigie.com/owa to access emails and setup iPhones etc.

 

Well, this is a rather large company and they own several smaller compaies, so all the smaller companies have their own domain names;

E.g

companyone.com
anothercompany.net
wejustboughtthiscompany.com
shortcompany.com
etc., etc.

 

Doesn't matter, same principal applies.
