OggSync works in the following configurations:

Most any configuration should work, however you must avoid sync loops such as this:

Once you’ve downloaded OggSync free trial, it will appear in your Outlook toolbar:

Choose “Configure Sync” and a window will appear which looks like this:

It may or may not have your Outlook Calendars Listed, if it does not use the “Add Folder” to add the calendar to the list.

OggSync can sync:

  • Private Calendars
  • Public Calendars
  • Exchange Public Calendars
  • Other Calendars

Once in the list, you can choose a simple sync mode, or opt to change to advanced sync mode. Generally you only want advanced if you are syncing multiple Google calendars to a single Outlook calendar.

If you are upgrading OggSync from a prior version, first uninstall the older version in the Control Panel ~ Uninstall Programs window.

If you were a prior user of OggSync, installing version 10 will reset your free trial, your previous license should transfer automatically assuming you are using the same email address, if not, contact
