You need to use the web browser interface of Teamup to access the iCalendar feed URLs. Read more about security, sync frequency, data range about outbound iCalendar feeds. You can view the events on an iCalendar feed, but you cannot modify them. Keep in mind that this is a one-way read-only synchronization.

This means that the calendar feed goes out from a Teamup Calendar to another calendar service, or to another Teamup Calendar.

ICalendar feeds are read-only and provide a periodic automatic synchronization between the source calendar (Teamup) and another calendar application.

To learn about inbound iCalendar feeds, see this article. This article describes how to set up outbound iCalendar feeds. You can set up a feed from your Teamup Calendar to other calendar applications such as Google Calendar, Microsoft Outlook or Apple’s iCal.
