Move your custom domain to Office 365

Outlook.com no longer supports new custom domain sign-ups. Therefore, the domains.live.com website and Windows Live Admin Center are being retired. You can continue to login to Outlook.com with your existing custom domain email addresses. After July 2014, domain administrators will no longer be able add or remove email accounts in your domain. Domain administrators are encouraged to move to Office 365 to get enhanced features and capabilities for modern enterprise-class mail, collaboration and communications.

Microsoft Office 365 service provides everything you need to manage email, calendars, contacts, documents, and team sites for your custom domain. Whether you’re using your custom domain for a small organization or a larger business, Office 365 will work across devices, from anywhere, and deliver a consistent, fast experience for all your domain account holders.

Office 365 subscriptions

Domain administrators who use the Windows Live Admin Center will receive an offer for a complimentary subscription to Office 365 for business. By simply clicking on the link in the email, you can take advantage of this excellent offer to try Office 365 for your organization. We think you’ll enjoy the breadth of features available to you.

Please don’t wait to redeem your Office 365 subscription offer. The offer expires July 15, 2014.

If you need help redeeming the offer, please contact Office 365 billing support.

Moving to Office 365

After you redeem the offer for a free three-month subscription to Office 365, follow these steps to start the service:

  1. Save the URL in your domain registrar that your MX record currently points to (for example, 12345678.pamx1.hotmail.com). If you later decide to switch back to Outlook.com, you'll need this record.

  2. Move your domain. Get more info on how to Add your domain to Office 365.

    If you need additional assistance with moving your domain, see Troubleshoot issues after changing your domain name or DNS records.

  3. Move your custom domain account holder data.

    Custom domain account holders can continue to use their email addresses to access other services that require a Microsoft account, such as Windows 8.1, Xbox, OneDrive, and Skype.

    After you have set up your custom domain in Office 365, email sent to your account holders will arrive in Office 365 instead of in Outlook.com. Existing email already delivered to Outlook.com will remain there.

    Your custom domain account holders have the option to move their email history, contacts, and calendars from their Outlook.com inboxes to their new Office 365 accounts. Each individual account holder must move their own data. As domain administrator, you'll need to instruct your account holders to move their email, if they want.

    Each account holder can follow these steps to move their email:

    1. Sign in to your Office 365 account at Mail.Office365.com or Outlook.Office365.com.

    2. On the top menu bar, click the settings icon Office 365 settings icon, and then click Office 365 settings.
    3. Click software, select a Language, and then click install.

    4. Once Office 2013 is installed, configure Outlook 2013 with the new Office 365 account info.

    5. In the section Use Outlook to move information between accounts follow the directions to export data from the desktop version of Outlook into Office 365.

    6. See Help users move email and contacts into a new Office 365 for business account for more information.

    For more information regarding the Outlook Web App, go to http://help.Outlook.com/.

If your account holders need assistance, please ask them to contact you as the domain administrator. Then, you can contact support through the Office 365 community.

If you're managing multiple domains, the Office 365 service supports the addition of up to 900 separate domains. Get info on attaching multiple domains to the service.

When the free subscription expires

If you choose to redeem the complimentary subscription to Office 365, you’ll receive a notification to renew the subscription prior to expiration. We think you’ll want to continue with the Office 365 service. But, if the service doesn’t meet your needs, you can return to using the Outlook.com email service by simply changing your MX record back to the URL you saved when you when you first moved to Office 365.

If you decide to return to the Outlook.com email service and discontinue use of Office 365, you won't be able to add or remove email accounts from your domain. Each account holder will still have the Outlook.com email history prior to the move to Office 365.

Account holders can move their email from their Outlook Web App back to Outlook.com:

  1. Export email from Outlook Web App to a PST file on their PC.

  2. Use the mail migration tool to import data from the PST file to their Outlook.com inbox.

Evaluating Office 365 options

Office 365 offers several options for custom domain administrators who want to continue to manage the email addresses in their domains. For more information about the subscriptions, review the Office 365 comparison guide.

Continuing with Outlook.com as your email service

If you decide that Office 365 doesn't meet your needs and you don’t redeem the complimentary subscription, your domain account holders will continue to have access to Outlook.com and other Microsoft services with their existing email accounts. No data will be lost. After July 2014, when the Windows Live Admin Center is retired, you'll no longer be able to add or remove email accounts for your domain.
