Hi Vincent,I'm experiencing the same problem with Odoo 10: "ValueError: year is out of range".I spent days in searching a solution about this, I also upgraded to Odoo to 11 but no way.

Did you find a solution meanwhile? It seems that actually, integration with Google Calendar is a mirage for Odoo, as far as these problem keep raising. It seems that NO solution has been found in more than a year...

Thank you

Marco

I have the same issue. It synced a few events back and forth but Odoo did not download my full Google calendar. It eventually stopped syncing completely after an hour and gave me nearly the same error as yours:

KeyError: '23-21171117000000'

This error occurs when I click "Sync with Google" in the calendar app within Odoo. In the technical details, I changed the sync time to 15 minutes and also ran a manual sync. Nothing happened.
