Email addresses from attendee list in Post Meeting content are wrong

[Molly Upbin]

When I download the attendee list from post-meeting content, most off the attendee's addresses show as some version of this: "458d1fa7-9e72-4e1b-bd08-f57715dec74a@guest.webex.localhost". 

Is this a bug in Webex, or is there a setting I can modify so I capture all attendee's correct addresses? Not being able to capture the attendee's email addresses is impacting my ability to send follow-up content.

The May 45.3 release stopped prompting unauthenticated guest attendees for their email address by default. This was an intentional change to reduce attendee friction/confusion. This was included in list of April 2025 announcements on the What's New in Control Hub help article (which admins should subscribe to updates for IMO). Administrators can re-enable it for a Webex Meetings site under Common Options > Security > Other > Email address; however, it is not a meeting host-accessible setting. You may want to consider requiring attendee registration instead - which you can customize.

Thanks for your feedback, Johnathan. I understand how to customize it when setting up a meeting/webinar from the User Hub, however, I normally set up meetings via outlook. It is possible to have the customization applied to setting up meetings in outlook, or will I always have to go to the Hub to schedule meetings if I want registration information? Thank you
