Setting up future meetings with participants using Teams calendar or Outlook integration
Hello @Karen Rockell
In Teams webinars, the attendee list and the registration list are handled separately. A person who registers for a webinar does not appear in the attendee list until they actually join the event. Registration details are typically available through the webinar management and reporting areas instead. This behavior can also vary depending on whether you are the organizer or a co-organizer.
I have found the Microsoft Article about this issue for you:
View webinar reports in Microsoft Teams
Note:
"Only organizers can view webinar reports. Co-organizer access is currently unavailable."
You can send me a screenshot or describe more about this issue so I can understand your needs better for further assistance. (Please kindly remove all personal information)
Looking forward to hearing from you!
