I have Exchange 2003 single server set as back-end server. The server is published externally through ISA 2004. RPC over HTTPs is configured and is working perfect. I am trying to configure Exchange to serve emails to mobile phone devices. The device I am trying is Nokia E75.
On Exchange server, I have followed a Microsoft article and I can now browse my email from an internet browser right to the Microsoft-Server-ActiveSync folder. This works from internal as well external networks. It also works on my mobile phone browser.
On my mobile phone's email client, I have configured everything, including the CA certificate, which now shows in the list of Authority Certificates. Also, I can see the request arriving at ISA server as Allowed Connection using the rule I specified (same rule as RPC over HTTPs, with Microsoft-Server-ActiveSync added as a path.) But, nothing returns. And, there are two cases to consider here:
1 - Setting the "Denied Access" option on the virtual folder as recommended by MS article (except for the IP of the Exchange server itself) returns an error message on the mobile that reads: Server requires secure connection. Change Profile > Connection > Secure Connection to Yes. In that setting, the Secure Connection option is actually set to Yes.
2 - When I remove that "Denied Access" option, the mobile phone seems to to synchronize but returns nothing, not even an error.
For the record, my domain name for authentication is different from my email domain name. Also, in Active Directory Users and Computers, I have more than one SMTP email address set for my user account. However, the email I am trying here is set as the primary email.
Any input is highly appreciated.
