If you need to use Microsoft Outlook, but prefer Time & Chaos, ChaosSync for Outlook will allow you to synchronize the Telephone Book, Appointments and To Do items in Time & Chaos with the Contacts, Calendar and Tasks databases in Outlook.
Once installed, the ChaosSync for Outlook program will appear on the Accessories menu within Time & Chaos. When launched, it automatically uses the current Time & Chaos databases and your default Outlook database.
All that remains for you to choose is the appropriate direction of sync for each section. You can have it do nothing, Time & Chaos overwrites Outlook, Outlook overwrites Time & Chaos or full Synchronize between the two.
