To change the primary alias from an outlook.com domain to your main email domain on a Microsoft Live.com account, you need to ensure that you have the necessary permissions and that your main email domain is properly set up in Microsoft 365. Unfortunately, Microsoft 365 Family subscriptions have limitations regarding domain management compared to business subscriptions.
Here are the steps you can take:
- Check Domain Setup: Ensure that your main email domain is added to your Microsoft 365 account. You can refer to the documentation on how to add a domain to Microsoft 365.
- Change Primary Alias: If your domain is set up correctly, you can attempt to change the primary alias by going to the Users > Active users page in the Microsoft 365 admin center. Select the user and manage the username and email addresses.
- Limitations: Keep in mind that if you are using a Microsoft 365 Family subscription, there may be restrictions on changing the primary alias to a custom domain. This could be why you are experiencing issues with Teams meeting invites.
If you continue to have problems, consider reaching out to Microsoft Support for assistance specific to your account type and configuration.
