The error in the interface

It's not because it's moved - OGCS already has identified the calendar item and it only trying to remove the reminder (because you are not syncing reminders). Why it's failing is a mystery though, known only to Microsoft as that message "object could not be found" is directly from Outlook and no further information is provided.

As a workaround, I'd suggest manually removing the reminder in Outlook so OGCS doesn't have a change to sync.

Neither outlook, nor gmail have the event on the day it's trying to update it. I've removed the reminder from the new date but that doesn't stop the error. I've had to uninstall because of this. I'd really like to be able to say to ignore the change or the error so it would have stopped

It would helpful to know the sequence of events. The issue is because the recurring series master is the 18-Oct and the master has been moved (though you're not saying where to). I'm guessing at something like:-

1. Create Outlook recurring series, starting on 18-Oct, includes a reminder 15 minutes before
2. OGCS syncs that to Google without a reminder
3. The 18-Oct occurrence is moved to another date - which one? Did this change sync via OGCS OK?
4. Some other change is made in Google which causes the Outlook master to update, but it fails *

* Note, when I do this, Outlook has to reset the entire series, so the master would move back to 18-Oct - I see OGCS also do this, and then immediately afterwards move it to the new date. It doesn't error for me.

The cux of the issue is the Outlook series has a reminder and you are not syncing reminders from Google. If you manually remove the reminder from the series (not just the individual occurrence on 18-Oct), then I think the error will stop.

* Another note: When manually editing the reminder on an individual occurrence in Outlook, when the series has eg 15 minutes, it actually displays "None". If it's changed to eg 30 minutes, saved and reopened, it shows "None" again. So clearly Microsoft reminders have their own issues 😶
