Using Classic Outlook on Windows for personal email, calendar, and contact management
I too am having this issue. Using the new Outlook on Windows 10.
I synced my Google calendar to Outlook by adding an internet calendar and using the secret address in iCal format. I am able to see all of the currently existing events that were already created in my Google calendar on Outlook.
However, I do not see any changes I make to existing events or new events I create.
I've already tried the delete/re-add method in Outlook. That is not an acceptable solution, and it also didn't even work.
