Create DNS records at 1and1 Internet for Office 365

 Caution    If you’re using Office 365 Small Business, we recommend that you choose to have Office 365 manage your DNS records. No matter which Office 365 plan you use, if you manage your DNS records at 1and1 Internet, there are significant service limitations, and you may want to switch to different DNS hosting provider:

  • The 1and1 Internet website doesn’t support TXT, SPF, or SRV records.
  • 1and1 Internet doesn’t allow a domain to have both an MX record and an Autodiscover CNAME record. This limits how you can configure Exchange Online for Office 365. You can have one of these configurations—but not both at the same time:

  1. Route all incoming and outgoing emails to and from Office 365 (MX record)
  1. Allow users to configure their Outlook profile settings by simply entering their email address and password into Outlook (Autodiscover CNAME record)

If you choose to manage your own Office 365 DNS records at 1and1 Internet despite the service limitations, here’s how to set them up:

If you’ve closed Office 365, start by gathering the information you need to create Office 365 DNS records.

 Note    Typically it takes about 15 minutes for DNS changes to take effect. However, it can take up to 72 hours for a changed record to propagate through the DNS system. If you’re having trouble adding DNS records, see Troubleshoot issues after changing your domain name or updating DNS records.

 Important    If 1and1 Internet is your email provider, when you select Other mail server, the flow of your email may break. To avoid losing email messages, we recommend that you complete these steps in the evening or on a weekend when email usage is low. If your mail flow is affected, you can restore it by clicking Reset after your domain is verified.

  1. Look for the first empty MX record field. This is where you’ll create your MX record; for example, it might have an MX 1/ Priority label.
  2. In the first record field for the new MX record, type or paste the Points to address value.
  3. The second record field (for the same MX record) is the priority field. For it, type a number that is higher than the number of your existing MX records. This creates an MX record that has a lower priority than your other MX records.

For example, if you have set an MX record for mail routing to 10, the highest priority you have, you could set the new MX record to 20. For more information about priority, see What is MX priority?

  1. Click Save.

When this succeeds, you’ll see the Process Successful page.
