Hiding email addresses

So you would need to create a separate invite for each person on the calls so that they cannot view each other's emails. There are two ways to do this. You could create each invite manually for each attendee. Alternatively there is a Zoom marketplace app, Salepager, for sending blind carbon copy Outlook calendar invites for Zoom meetings that hides each attendee's email address from the others.

You could create a distinct Outlook invite for each invitee manually. If you want to automate this there is a Zoom marketplace app, Salepager, for sending Zoom invitations BCC without showing to each invitee the addresses of the other invitees.
