How do I enable attendee email after publishing a webinar

Dear @Michael Maji

Based on your description, the reason the “Enable attendee email” option is greyed out is because the webinar event site has already been published. In Microsoft Teams, this specific setting can only be configured before publishing the webinar. Once the site is published, the setting becomes locked and cannot be modified for that event. For reference: Manage webinar emails in Microsoft Teams

Because attendee emails were not enabled at the time of publishing, the system will not send registration confirmations, reminders, or other automated emails for this webinar. This is why your test registration did not trigger any notification emails.

At this stage, there unfortunately isn’t a way to enable attendee emails for the existing webinar. The recommended approach is to create a new webinar and ensure that “Enable attendee emails” is turned on before publishing. Once enabled and published, Teams will automatically send registration confirmations and reminders to attendees.

If recreating the webinar is not feasible, you may need to manage communications manually (for example, by exporting the registration list and sending emails separately).

I also recommend double-checking this setting for future webinars before publishing to avoid the same limitation.

I hope the information shared is helpful. Thank you for your understanding, and please let me know if you would need any support when recreating the webinar
