Sentral Calendar has ical/ics support, and this can be used to view your Sentral Calendar in an external system, such as Skoolbag, Microsoft Outlook, or any program that supports ical/ics subscription.

Important to Note
To modify Calendar preferences, you need to be either either an Administrator or the owner of the calendar you want share.

To enable a Sentral Calendar to be viewable via an external system, you need to ensure that the following has been setup.

• Login to Sentral and use the module menu to go to the Calendars module
  
• Click the name of the calendar you wish to share publicly
  
• Click the Preferences button above the calendar
  
• Update the View Privileges setting to be Open: Anyone (note that this will mean anyone with the link will be able to see the entire calendar)
  
• Click Save
  
• Click Return to Calendar
  
• In the browser's location field, append the text ?type=ical to the URL
  
• Copy this whole URL to share the public iCal link with others
  

Please note: If you are linking with an external system, the URL should be the publicly accessible URL, which in your case would be using the school's Reverse Proxy address of http://sentral.schoolname.edu.au/webcal... and not any internal school-only links, such as http://1.1.1.1/webcal/...

For Outlook
Different Versions of Outlook may differ slightly, but in Outlook.

• Go to Calendars
  
• Right click on My Calendars
  
• Select Add Calendar, From Internet
  
• Paste in the URL from the process above
