After you add a custom domain for your organization (like fourthcoffee.com), you can send and receive email with the domain (like firstname.lastname@example.org) right in the Office 365 portal. But if you also want to use Office 365 email with your custom domain in your Outlook program on your desktop, you and others in your organization can do that too.
These steps are for Outlook 2013, but you can also set this up with Outlook 2010 or 2007. The steps are a little different, though, and you should make sure you’ve run Office 365 desktop setup first so it’ll work correctly.
- On your desktop, open Outlook: Start > All Programs > Microsoft Office > Microsoft Outlook 2013.
- Click File > Account Information > Add Account.
- Select Email Account, and then type your name and your Office 365 email address (it’s also your user ID) and password.
- Click Next. Outlook checks with Office 365 and sets up your mailbox.
- Follow the rest of the instructions to finish adding your account to Outlook.
Tip You can also set up Outlook to work with your original onmicrosoft.com email address, if you don’t have a custom domain or you’re just trying out the service.
Before you set it up, make sure your Office 365 email is working in the portal
For Office 365 email on your custom domain to work with Outlook on your desktop, email first has to work correctly in the service. If you can’t send and receive email in the Office 365 portal, check for these possible issues. After email works in the portal, try again to set up Outlook with your custom email address.
- If you’re using a Small Business plan and you chose to have Office 365 manage your DNS records: When you added your custom domain, did you finish all the steps in the wizard, including completing the process to change your name server (NS) records to Office 365? That final step allows Office 365 to set up email with your domain for you.
- If you’re managing your own DNS records: Did you set up the MX and CNAME records for Exchange Online at your DNS hosting provider? They’re required for email to work. You also need to create those records if you’re using a Small Business plan and you skipped the last wizard step, (Learn how to set up the email records at many popular domain registrars.)
- If you’re having trouble getting email to work in the portal: If Office 365 email doesn’t work in the portal, it probably won’t work in Outlook on your desktop either. Track down the Office 365 issues first (see the steps in the Troubleshoot problems section below), and then set up Outlook with your Office 365 email address.
- Follow step-by-step instructions to set up email accounts in different versions of Outlook. You can use Outlook 2013, 2010, or 2007 with Office 365.
