Troubleshooting Exchange ActiveSync
Troubleshooting issues relating to ActiveSync can be difficult because there are several factors that come in to play. It can often be difficult to determine where a given problem lies. Issues could be related to the handheld device itself (hardware), the software that is allowing you to connect to your server (Microsoft’s Exchange ActiveSync app, RoadSync, Mail 4 Exchange, etc), settings on the server itself (certificates, mobile services access, etc), or anything in between (ISA server, other firewalls and/or middleware). With such a large variety of complex setup possibilities, it can be a bit tricky to resolve this type of issue.
Chris De Herrera (Pocket PC FAQ; Microsoft MVP) has a very thorough ActiveSync Troubleshooting Guide which (along with the several other articles he has posted about ActiveSync) can be a huge help when rolling out or troubleshooting a mobile email solution. Some of the material is a bit dated, but most of it still applies in most situations. Our IT and Engineering departments have found this FAQ to be a valuable tool in many situations; hopefully it will help a few of you out as well.
