A SBS 2003 R2 exchange enviroment and apx 70 WSs which are located in 22 different cities here in Finland. All remote WSs are not joined to domain and they use RDP over HTTPS Outlook client.
I need to add a new emaildomain to the server. Currently I have a public SSL certificate for currentdomain.fi. In the future I need to have newdomain.fi as a primary email domain while currentdomai.fi needs also work. Also the webmail address have to be https:/mail.newdomain.fi/exchange
. The currentdomain.fi needs to work to the end of this year and then stop.
What are the major steps?
Do I have to buy a SAN (subject alternate name) SSL certificate in order to make both domains work same time?
If a SAN certificate is needed isn't it so that the ISP has to setup DNS/MX for newdomain.fi to point to my server before I can buy the certificate (otherwise I can't receive the certificate to email@example.com
At what point should I run CEICW again to start use new public SSL certificate (SAN if needed)?
Do I have to make changes to client Outlooks (change Exchange Proxy https address to mail. newdomain.fi) now or at least at the end of the year?
Thanks in advantage
