A VCS file contains information about events in your Calendar. This information can be imported into other calendar applications. If you are a Mac user and would like to be able to open your VCS files from iMeet® Central in Outlook instead of iCal by default, follow these steps:
1. Find your VCS file via "Finder".
2. While holding the control key, click on the VCS file (two finger click on trackpads) and select "Open with".
3. Select "Other...".
4. In the "Choose Application" window, select Microsoft Outlook.
5. Make sure the "Always Open With" checkbox is checked.
6. Click "Open"
Now any VCS file will open in Microsoft Outlook by default. You can always change this setting at your discretion.
