if you google

sync gmail calendar outlook

you will find dozens, maybe hundreds of applications that will sync outlook calendars with the ical format used by google's web based calendar and many others out there. I don't have experience with any of them, but I do know people have gotten them to work without too much trouble. You continue working on outlook, you let anybody else who needs to access your calendar do so with the gmail calendar.

Some are free, some are low cost.
