Thanks Amit!How do I figure out if ActiveSync is already installed in my exchange server 2003? I want to see how to use an iPhone 3GS with exchange. And it requires ActiveSync... has anyone used this type of phone with Exchange Server 2003?Thanks again.

Exchange 2007 supports ActiveSync with iPhone but not sure about Exchange 2003, however you can configure IMAP on iPhone with Exchange 2003, check below guide...

Exchange ActiveSync is supported by iPhone 2.0 or higher and for that to work we need Exchange 2003 SP2 or Exchange 2007 SP1http://images.apple.com/iphone/enterprise/docs/iPhone_MS_Exchange.pdfYou can check out the setup process from these screenshots http://blog.fosketts.net/2008/07/10/how-to-set-up-iphone-exchange-activesync/ActiveSync is preconfigured on the Exchange Server, thus it works out of the box. The only thing that you need to consider is that1. You have a valid SSL certificate2. The port 443 on the firewall is not blockedAnd ActiveSync would work just fine...Harpreet Singh Khandiyal (http://support.microsoft.com/kb/555375)
