My users are complaining of disappearing Calendar events in Outlook. It's not just recurring events, but other ordinary events too. The user that lost his Calendar entries also has a PDA which uses ActiveSync.
Given all that, my question is - where do I start on this? What likely event ID's should I troll through? The problem is that they want it solving quickly in a minimal amount of time, but I could be working on this one all night and still not pull up anything meaningful!
