Create a mechanism where all Smart Cloud Org Owner(s) & Business Owners have the ability to export a full and complete list of all members within their own Smart Cloud communities which will include the full list of members and their information.
The Use case is due to regulatory procedures, the Community owner is trying to re-validate the Community Membership for audit purposes but can't since they have no access to Guest Emails.
The only way to obtain additional information would be to contact the Community owners who invited the user and request more information. Only if a guest user is in your network has agreed to share their information with you can a Community Owner see their email. Currently the org Business owner/admin has no access to this information.
