Google Calendar – Does Outlook Sync Tool Support Multiple Users?

There doesn't seem to be any way to get more than 5 notifications for one event in google calendar.

One workaround that may be useful is to create two (or more) events starting at the same time as the event you (really) want to remember, and then add five reminders to each of those.

There's an article on this here. I've not checked that it works, but it seems pretty straight forward. The essence is that instead of importing the calendar, you add the URL of your event feed as a public calendar - here's a summary of the steps:

1. In Facebook click on "Events"
2. Click on "Export Events" and copy the URL
3. In Google Calendar go to "Add" under "Other calendars" and choose "Add by URL"
4. Paste the URL you copied from Facebook and click "Add"

If you run into issues with private events not showing properly then check out eventbusyfix.info. This site acts as an inbetween to clear the private flag and enable Gmail to show them properly (Thanks to prestomation for this tip)

Hope that helps!
