Since I started using Wireless Sync, my Exchange calendar has become unreliable. Specifically, if someone else cancels or moves a meeting, Wireless Sync sometimes puts it back the next time it synchronizes. Lots of similar problems.

I have a "delegate" in Exchange, my secretary, who works with my calendar from her own Outlook, and I'm sure this complicates things.

I'm thinking of making the calendar sync one-way, i.e. Outlook will push data to the Treo but not the other way around. How can I do this?
