Microsoft's Mac OS X Exchange client, Entourage, operates in a syncing cached mode where it downloads server-side data, stores it locally, and occasionally synchronizes that data with Exchange. This setup in effect provides a local backup of your Exchange data that you can read when offline. At the university for which I provide computer support, I have seen more than one case where server-side issues have made the local backup of contacts and calendar items look very useful. Unfortunately, Microsoft does not provide any way to export or restore from cached Exchange data in Entourage.

If you find yourself in a similar situation, here's a workaround that takes advantage of Entourage's integration with Apple's Sync Services:

This method is for use when a user has an Entourage identity with an Exchange account that contains locally cached contact/calendar data that differs from and is preferable to the server-side Exchange data. This method will restore the locally cached Exchange contacts and calendar to overwrite the server-side Exchange data.
