An outbound iCalendar feed is a feed from Teamup to another calendar service (or to another Teamup calendar). 

If the feed will not sync or stops updating, here is what to check.

• Is the feed URL valid? Use one of the freely available iCalendar feed validators such as https://icalendar.org/validator.html. There may be a typo or copy/paste error; this is a quick way to make sure the feed URL is correct. 
  • If the feed URL is not valid, go back to the source Teamup calendar and obtain the feed URL again. 
  • If the feed URL is valid, proceed with the next troubleshooting steps to isolate the issue. 
• Try the feed in a Teamup live demo calendar. 
• Try a different browser: If it doesn't work in your default browser, try the feed in your own calendar or a live demo calendar in a different browser. 
• Test the feed in a different calendar, e.g. Apple or Google Calendar. 

• Note that refresh rates are dependent on the calendar receiving the feed: Teamup refreshes the feed source immediately after each change. However, the update frequency a user experiences varies depending on the subscribing calendar program.
