Re: Teams Webinar registration link fails

It would be great to understand the true cause/solution to this issue. Seems like a bug in Teams. 

I have over 100 people registered for my webinar in 2-weeks and as the organizer of the webinar no longer have the ability to manage the event. Similarly received the "The event is unavailable" error message. I event is still scheduled on the calendar and to my knowledge no cancellation emails have been distributed. 

Potential cause: I noticed that someone, presumably within my organization, attempted to Join the meeting yesterday. Since that, I've not been able to manage or approve new registrations. 

 

Update: Logging out, restarting device and signing back in did not resolve the issue. However, accessing Teams in the web browser experience allows me to manage the event as expected. Seems to only impact the Teams app experience.
