Hi @Stuart Butler
If they can be shared, how many times can they be used by others, is there a limit?
In webinars, the number of participants can be up to 10,000, the number of fully interactive users is 1,000, and those over 1,000 only have view-only functionality.
can we skip having a registration page for most people (i.e. register ourselves for the event and send the one joining link to the 300 attendees).
There is no way to skip the registration page, attendees are required to fill out the registration form, which is by design. For more details about Teams Webinars, you could refer to: https://learn.microsoft.com/en-us/microsoftteams/quick-start-meetings-live-events
