Reference: Zoom Limitations for Virtual Classroom Integration

Limitations

Limitation	Description	Recommendation
Licensed users on business, education, enterprise accounts can host only a maximum of 2 concurrent meetings.	If you schedule a third session that overlaps with the first 2 sessions with the same host: Learners will be unable to join the third session on the scheduled date and time. The host will be unable to start the third session until one of the earlier sessions concludes. A cohost will be able to abruptly end the ongoing 2 sessions and start a third session. This limitation can cause significant disruptions for both learners and hosts. To mitigate these issues, Workday adds these to help you manage and optimize the scheduling of virtual classroom sessions, ensuring a seamless experience for all participants: A new Organizer field on the Schedule Course Offering task. This allows you to select an instructor whose Zoom account will be used to generate a Zoom link. A critical validation on the Schedule Course Offering task to prevent scheduling conflicts. If you attempt to schedule a virtual classroom session with an organizer with a start date and time that overlaps with another existing session with the same organizer as the host, Workday triggers an error prompting you to select an alternate time.	Workday strongly recommends that you update the course offering and add the lesson level instructor and organizer after you identify an instructor to avoid limitations from Zoom related to concurrent meetings.
Only up to 100 requests per Zoom account per day.	If you exceed the limit, Workday fails the integration event.	Workday recommends that you don't use 1 Zoom account to schedule more than 100 virtual classroom lessons per day.

Additional Considerations

Settings	Description
Meeting co-host	To designate someone as a host during the meeting, you need to enable the Co-host option in your Zoom tenant.
Zoom email settings	Zoom automatically sends emails to alternative hosts, whether you enable calendar integration or not. Workday recommends that you disable email settings in Zoom if you enable calendar integration.
Integration system update	If you edit a course offering to update the integration system from Zoom to Microsoft Teams for a virtual classroom lesson, the virtual classroom lesson will still reflect on the Zoom application for the organizer and instructors.
Zoom and Microsoft Teams integration systems	If you use both Zoom and Microsoft Teams integration systems and you add the Organizer class report field to the calendar message template, Workday populates the Organizer field only in Zoom calendar invites and the field remains blank in Microsoft Teams calendar invites. For a course offering with a virtual classroom lesson, if you use Microsoft Teams integration without an instructor and update the integration system from Microsoft Teams to Zoom, the integration event will run and complete but with errors. Workday will create a Zoom meeting link but won't delete the Microsoft Teams meeting ID.
