Integrating your FlipperForce Calendar to your External Calendar like Google Calendar, Outlook or iCal is a one-way sync that pushes events from FlipperForce to your External Calendar.
The FlipperForce events that are synced to your External Calendar only allows your External Calendar program read-only access.
To edit a Schedule, Task or Event from your External Calendar simply open up the item and click the link to open it directly in FlipperForce and make changes.
