How to sync drupal event calendar with Outlook Calendar

i am using drupal events calendar and i am creating events. Now i want to view these events automatically in the Microsoft Outlook calendar when i look into my outlook.

Currently i am exporting the drupal calendar events as calendar.ics files and then importing them in the outlook manually. How can i automate this process?

I开发者_高级运维 am sure that Outlook can import files of format ".ics" and so i am just curious to know how can i import an ics file into my Outlook, or put in other way, how to add events to outlook calendar with php ?

• With Outlook 2007, you can subscribe to ical calendar (you just have to provide url to your ics file).
• With Outlook 2003, you can use a plugin to sync with ics file : http://remotecalendars.sourceforge.net/

PS: not a drupal issue.
