Outlook Calendar Events Does Not Sync On Zoom Web For Upcoming Meetings

[jonesitss]

One of my users has been having issues with Outlook Calendar invites not showing up on Zoom web calendar and upcoming meetings. My users are mainly using Mac devices. I noticed that users who are assigned co-hosts to events don't have their calendar events showing up on their upcoming meetings.

The events show up on the Zoom app and their Outlook calendars, but it does not appear on Zoom web.

As an admin, I enabled bi-directional sync, but that still did not sync the one-off Outlook calendar events to their Zoom web calendar. 

We're running on O365 Business Standard licenses as well for Outlook.

Are there any troubleshooting steps I can take to remediate this issue?
