You can add a Zoom Meeting to your Google Calendar events directly from Google Calendar using the Zoom for GSuite Addon.   This tool also allows you to quickly update Zoom meetings created in Google Calendar.  Any Zoom meetings created with the Zoom Chrome Extension must be updated in the Zoom Web Portal:  https://stonybrook.zoom.us

Notes about using Zoom with Google Calendar (using the Zoom for G Suite Add-on)

• When using the add-on, make sure you are not signed in to multiple Google account with the add-on installed. This will cause issues when scheduling Zoom meetings using the add-on.
• If you are rescheduling a Zoom meeting from Google Calendar, edit the calendar entry and change the meeting date/time. Do not drag and drop the calendar event or copy the meeting details to a different calendar entry.
• If Zoom Meetings started from/created in Google don't work correctly, clear your browser cache, remove all browser cookies, sign out of the add-on and then sign back in and reauthorize it (if prompted).
