Using Classic Outlook on Windows for personal email, calendar, and contact management
That's an interesting suggestion. But my Gmail calendar doesn't show up as an Internet Calendar, but is a Shared Calendar using the shareable calendar link. As a Shared Calendar it seems with the Cached Exchange turned off, that it doesn't update the calendar at all, even with new events, let alone update changes to existing events.
Yes, have the same issue. I don't show a cache option at all. I'm running Windows 11, Office 365. When I add the calendar, which I've removed and reloaded several times, it just shows a static snapshot of the current google calendar (using the secret iCal method), but then does not update additions or deletions (definitely not within hours of the change, so suspect never).
It's almost like Windows does not want to play nice with Mac/Google and the iCal option.
I have also added the google email inbox to see if that was the source of the static view, but it did not fix the issue.
