I've tried changing "Calendar" to "ITOoO" (one of my new outlook calendar groups), but I get the error:
Office365.V2CalendarPostItem failed: The method 'V2CalendarPostItem' has an invalid value for paramete 'Subject'
Now I am assuming this is because the app could not find my defined calendar "ITOoO", but I can not figure out how to change the calendar to anything other than the stock "Calendar" "Birthdays" and "United States Holidays".
I've been told that Outlook is set to sync changes about every 4 or 5 hours in this organization; however, these changes have been made about 20 hours ago, and still no luck.
Am I doing something wrong? If I got the group ID, and then the Calendar ID from that group, would that work?
