Important
Starting February 1, 2026, organizations using premium custom HTML templates for Teams Events email notifications must set up and verify their sending domain in Microsoft 365. Without this, custom templates can't be used, and event emails must originate from an authenticated, customer-owned domain.
Overview
With a Teams Premium license, you can decide whether event organizers and co-organizers can edit email templates for their webinars and town halls. With email templates, organizers and co-organizers can manage waitlists, remind attendees about webinars they registered for, and provide clear instructions for attendees before, during, and after the event.
Your webinar organizers and co-organizers can edit the following email communication templates:
- Attendee cancellation
- Attendee pending approval
- Attendee registration
- Attendee rejection
- Attendee waitlisting
- Event recording available
- Webinar cancellation
- Webinar date time update
- Webinar reminder
For more information on the webinar email communications experience for your users, see Manage webinar emails in Microsoft Teams.
Your town hall organizers and co-organizers can edit the following email communication templates:
- Event invitation
- Event recording available
For more information on the town hall email communications experience for your users, see Schedule a town hall in Microsoft Teams.

Through PowerShell, you can manage whether organizers and co-organizers can edit email templates for their webinars and town halls. The -AllowEmailEditing parameter in the CsTeamsEventsPolicy cmdlet controls whether your users can edit email communication templates.
The following example turns off -AllowEmailEditing so organizers and co-organizers can’t edit any email templates:
Set-CsTeamsEventsPolicy -Identity <policy name> -AllowEmailEditing Disabled
