Teams Premium: Unable to edit emails for Town hall & Webinar

Hello @Logan, 

You’re not alone in running into this, especially in multi-domain tenants.  

This message usually means the tenant hasn’t finished setting up a domain for Microsoft 365 notification emails yet, which Teams Premium relies on for Town hall and Webinar email customization. 

Even though the domains are verified, one domain still needs to be explicitly selected and fully configured for M365 notifications in the Microsoft 365 admin center. Until that’s done, Teams will disable the email editing option. 

To set up a domain for Microsoft 365 notification emails, please follow these steps: 

1. Find your Microsoft 365 admin: If you haven’t yet reached out, here’s a helpful guide to locate your Microsoft 365 administrator: How do I find my Microsoft 365 admin? - Microsoft Support  

2. Ask your admin to: 

• Sign into Microsoft 365 Admin Center 
• Navigate to Settings > Org Settings 
• In the Organization profile tab > choose Send email notifications from your domain 
• Select one verified domain (for example: events.company.com or the primary SMTP domain) and set up the Username. 
• Save the configuration 

It’s also important to make sure the domain has the required DNS records in place, including an MX record and SPF with Microsoft included. DKIM and DMARC aren’t strictly required but are recommended. If DNS validation isn’t fully completed, Teams will continue to block editing. 

After the configuration is saved, allow up to 24 hours for the changes to apply. Once that window has passed, sign out and back into Teams, then reopen the Town hall or Webinar and check the Emails section again. 

Once that setup is finished, the Edit links for event and recording emails should appear as expected. 

For your reference: Select the domain to use for email from Microsoft 365 products - Microsoft 365 admin 

Hope this helps clarify what’s happening. Please let me know how it goes or if you have any questions along the way.

The error appears because email template editing for Teams events is controlled by the event email-communications configuration and policy, not just by having Teams Premium licenses.

For organizers to edit webinar and town hall emails, the admin must:

1. Ensure email template editing is allowed in Teams events policies
   • In the Teams admin center, go to Meetings > Events policies.
   • Open the policy assigned to the organizer (or create a new one).
   • Turn Customize event emails to On.
   • Select Save and ensure this policy is granted to the organizer.
   • This corresponds to -AllowEmailEditing Enabled in CsTeamsEventsPolicy.
2. Verify via PowerShell (optional/admin)
   • Run Get-CsTeamsEventsPolicy and check the value of AllowEmailEditing for the policy assigned to the user.
   • If needed, enable it:

          Set-CsTeamsEventsPolicy -Identity <policy name> -AllowEmailEditing Enabled
     

3. Confirm Teams Premium feature access
   • If trial Teams Premium licenses were used, verify they are still valid. Expired trials prevent use of Premium features.
   • If licenses are valid but features still don’t work, run the Teams Premium Details test in the Microsoft Remote Connectivity Analyzer for an affected user to confirm the account meets all requirements.

Once the admin has enabled Customize event emails (AllowEmailEditing = Enabled) and confirmed valid Teams Premium access, organizers should be able to edit webinar and town hall email templates without seeing this error.
