Fix the error “Editing isn't available because your org hasn't finished setting up your email domain for M365 notifications yet”
Recently, a user received the following error message in Teams when trying to schedule a webinar and send email notifications:
Editing isn't available because your org hasn't finished setting up your email domain for M365 notifications yet. Contact your admin for help.
From what I could see, the user was licensed correctly and they have the permissions they need in the Teams Events settings. I searched for the text of the error message, but couldn't find any results on Google.
Here are the steps for how I got it working.
After some looking around, I found that Microsoft changed the requirements on February 1, 2026 to require additional setup in M365.
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.
After reading this note, I was able to find the option in the M365 Admin center.
Before getting started, you must have the Global Administrator role in Entra ID/M365, or a custom role with the MSGraph permission microsoft.directory/organization/allProperties/allTasks
The user will need an M365 license with Teams (any Business or Enterprise license: Business Standard, E3, etc.) and a Teams Premium license.
Also, make sure that you have allowed Teams Webinars for the user from the Event settings page: https://admin.teams.microsoft.com/one-policy/settings/events
- Navigate to the M365 Admin center: https://admin.cmd.ms/ and click Settings > Org settings
- Search for “Teams”
- Click on the “Send email notifications from your domain” option.
- In the configuration pane, enable the “Use a custom send-from domain address” and add something like “noreply” and select your primary domain.
- Click the Save button.
After changing this option, it can take about an hour for the changes to take effect. The user may need to restart Teams and/or log out and back in for the policies to refresh.
