[itdiscuss] iPhone and Exchange 2003 Active Sync

[Tim Larson]

To get an iPhone working with Exchange:

1. Set up OWA with an SSL certificate.  Don't use a wildcard SSL certificate - ActiveSync on Windows Mobile devices doesn't handle wildcard SSL certs properly.  Make sure that OWA is accessible externally.

2. Go into the settings in Exchange Administrator for the user in question and make sure their account is allowed to use Mobile Devices (each account can have OWA, Mobile Device use, IMAP, and POP enabled or disabled).

3. Make sure the iPhone has version 2.0 installed.  The 3G iPhones come with this out of the box, whereas the older iPhones need to be upgraded.  This is a free upgrade for anyone with the iPhone, and it's a $20 or so upgrade for anyone with the iPod touch.

4. Set up the iPhone with Exchange.  It's very straighforward - you add a new email account to the iPhone, tell it that it's an exchange server, then give it the server name, username, and password, and you're done.
