Mobile Messaging Deployment Guide
Step-by-Step Guide to Deploying Microsoft Exchange Server 2003 SP2 Mobile Messaging
If you are considering deploying some mobile devices with Exchange ActiveSync email and PIM capabilities (or if you’ve already deployed some), there is a must read guide from Microsoft that you may find quite helpful. Jason Langridge’s Weblog has a very similar version of this available as a white paper (.doc) that you can download. It’s basically a step-by-step walkthrough to set up mobile messaging with Exchange Server 2003 SP2 and Windows Mobile 5.0 devices. However, one of the nice things about this is most of this deployment info still applies even if you are using a different Exchange ActiveSync solution (Such as RoadSync or Mail 4 Exchange) for a non-Windows Mobile 5 handheld (such as a P990 or E62).
