Teams Webinar Attendees report

Question

Hi All,

I am organizing a teams webinar and i am unable to view the number of people that have registered for the webinar. The participant report has stopped updating. So now i do not know how many people have registered. It stopped updating after i started the webinar during our practice.

How i do get an up to date report on the number of participants/attendees.

Hi @Arnold 

Welcome to the Microsoft Q&A forum. 

Thank you so much for taking the time to sharing your situation. 

Based on your description, it sounds like registration is still functioning correctly, but the Participant/Attendance report stopped updating after you launched the webinar during your practice session. This occurs because Microsoft Teams creates a separate report for every session tied to the same webinar, including short test sessions, which can cause the live registration view to appear frozen or incomplete. 

Although the test session report can’t be removed or overridden, you can access accurate, up‑to‑date registration data, you just need to check it in the correct section. 

Here’s what you can do: 

1/ Before the event (check registration only): 

• Open Teams > Calendar > double‑click your webinar > go to Registration > Attendee status to track page views/registrations/cancellations. 
• You can see: View webinar reports in Microsoft Teams 
• This is the right place for pre‑event numbers, it’s not attendance. 

2/ After the event ends (get accurate attendance): 

• Open the past webinar from Teams > Calendar > select the Attendance (or Reports) tab > Download the CSV. 
• That post‑event report includes start/end times, attendee count, roles, and per‑attendee duration for the actual webinar. 
• A short test session will appear as its own separate session, just don’t select it. 

3/ If you still see only the practice minute: 

• Make sure you’re on the correct occurrence (Teams keeps unique reports per instance). 
• Confirm you’re the organizer (only organizers can view webinar reports). 
• Ask your IT admin to verify that the Attendance & engagement report policy is On in the Teams admin center. 

For reference, you can see: 

• View webinar reports (Registration & Attendance) 
• Manage meeting attendance reports 
• Admin policy for Attendance & engagement report (if reports don’t appear for organizers)
