Quicken has the ability to synchronize bill and income reminders to Microsoft Outlook. This lets you view Quicken reminders right alongside any other events you have scheduled on your personal calendar. I think this is a useful feature, but it is limited only to Microsoft Outlook users.
I have submitted a feature request to Intuit to add iCAL support for the bill and income reminders. By adding the option to sync the reminders out to a file using the well-supported iCAL standard, non-Outlook users would be able to use their calendar program of choice to view the reminders.
If you think this would be useful, please click on Help -> Submit Feedback right there in Quicken and shoot off a similar request. The more requests Intuit gets for a particular feature, the more likely they are to implement it.
Here is my original request if anyone wants to cut and paste:
Feature request for Quicken Home & Business: Add the option to synchronize bill/income reminders to a specified iCAL file in addition to synchronizing with Outlook. This would allow the reminders to be viewed by a much greater range of calendaring tools and not limit the sync feature to just Outlook users.
Thanks!
