Answer 1

To change your domain/email address in Microsoft 365 without canceling your account, you can follow these steps:

1. Add your new domain: Go to the Microsoft 365 admin center, navigate to Settings > Domains, and select Add domain. Follow the steps to confirm that you own the domain.
2. Change user email addresses: Once your domain is added, go to Users > Active users. Select the user whose email address you want to change, then on the Account tab, select Manage username and email. Edit the username to reflect the new domain and ensure the correct domain is selected.
3. Sign out and back in: After making these changes, sign out of Microsoft 365 and then sign back in with the new email address.

Make sure to update any necessary DNS records for your new domain to ensure email delivery works correctly.

Hi @Tinayia Washington, 

Thank you for posting your question in the Microsoft Q&A forum. To better understand your request and provide better support, could you clarify a few details:  

• I noticed your question is tagged under Microsoft Copilot | Microsoft 365 Copilot | Development, so I’m not entirely sure about your environment and would like to confirm. Are you using Microsoft 365 for Business, or is this for a personal account? 
• Do you want to change the primary domain for your entire organization, or are you simply looking to update your own email address? 
• Is your domain currently managed through Microsoft 365 or by a third-party provider? 

These details will help me point you in the right direction. Please feel free to reply whenever it’s convenient and I’m here and happy to assist further if needed.
