Does OggSync support a one way sync from Google?
Not directly, but it can be done. You will need to create a new gmail account for OggSync to use, then share your Google calendars with that Gmail account in READ ONLY mode. Then point OggSync at the read only gmail account. Q) I’ve set up OggSync to sync a Google calendar, but events aren’t appearing on my phone (or in Outlook). A) If you have recently changed accounts, verify that your calendars are still checked in the “select which calendars sync” page.
