Summary:
When iCal Feed is used, only the respective user's TimeOff is listed in the Calendar instead of showing all users TimeOff Bookings, but other users TimeOff Bookings are showed in the Web TimeSheet TimeOff calendar.

Cause:
While Generating the iCal Feed URL the option to exclude other user's TimeOff is selected. This option is enabled by Default.

Resolution:
Uncheck Only include my time off option before Generating the iCal Feed URL.
