Additional settings-related features and issues within Microsoft Teams Free
Hello Jennifer. At this time Microsoft Teams does not support a native Bcc (blind carbon copy) option for meeting invitations. This means that whenever you invite a group to a meeting, all the invitees can see each other's email addresses. When you have guests who are external parties, and especially when inviting very large groups, privacy can be a concern. The best headache free workaround is to send individual calendar invitations from Outlook. Each invitation should still include the same meeting link, and each invite can go to one recipient at a time, but in the end it will behave like Bcc. Each invitation will show on the individuals calendar and the invitee's will not know those others included on the guest list for the meeting.
Best regards,
