Create DNS records at Dreamhost for Office 365

Check the Domains FAQ if you don't find what you're looking for.

If DreamHost is your DNS hosting provider, follow the steps in this article to verify your domain and set up DNS records for email, Lync, and so on.

After you add these records at DreamHost, your domain will be set up to work with Office 365 services.

To learn about webhosting and DNS for websites with Office 365, see Use a public website with Office 365.

Note

Typically it takes about 15 minutes for DNS changes to take effect. However, it can occasionally take longer for a change you've made to update across the Internet's DNS system. If you're having trouble with mail flow or other issues after adding DNS records, see Troubleshoot issues after changing your domain name or DNS records.

Add a TXT record for verification

Before you use your domain with Office 365, we have to make sure that you own it. Your ability to log in to your account at your domain registrar and create the DNS record proves to Office 365 that you own the domain.

Note

This record is used only to verify that you own your domain; it doesn't affect anything else. You can delete it later, if you like.

  1. To get started, go to your domains page at DreamHost by using this link. You'll be prompted to Sign in.

Now that you've added the record at your domain registrar's site, you'll go back to Office 365 and request Office 365 to look for the record.

When Office 365 finds the correct TXT record, your domain is verified.

  1. Choose Setup > Domains.

  2. On the Domains page, choose the domain that you are verifying.

Add a TXT record for SPF to help prevent email spam

Important

You cannot have more than one TXT record for SPF for a domain. If your domain has more than one SPF record, you'll get email errors, as well as delivery and spam classification issues. If you already have an SPF record for your domain, don't create a new one for Office 365. Instead, add the required Office 365 values to the current record so that you have a single SPF record that includes both sets of values.

Follow the steps below.

  1. To get started, go to your domains page at DreamHost by using this link. You'll be prompted to Sign in.
