Zoom meeting changes or cancellations not updating on client's outlook calendar.

My client is experiencing calendar issues between Zoom, Google Calendar and Outlook. Calendar invites are sent via Zoom, and when canceling or making changes to these invites (in Zoom), the updates are reflected correctly in Google Calendar but not in Outlook. This issue is happening the most with recurring invites, where the updates either don’t sync properly or fail to reflect the changes in Outlook. Has this happened to anyone else and if so have you figured out a work around?
