I have a customer whose setup consists of the following:
Exchange 2003 installed on a Win2K server
Running OWA (and )
ActiveSync for smartphones
Customer wants to apply a SSL certificate from a third party vendor to encrypt communication to clients and smartphone users. I would like to make the transition as smooth as possibly especially because the end users (about 200 of them) will need assistance to change their phone SSL settings.
I'm familiar with the logistics of creating the CSR for the certificate, applying the cert to Exchange IIS and enabling Port 443 at the firewall for communications.
My question is: Once the certificate is applied to the Exchange server, will the smartphone users still able to communicate through port 80 and continue to pull email as normal? Or once the Certificate is applied, will everyone need to change their settings immediately in order to access their email through 443?
