Create DNS records at Dynadot for Office 365

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

These are the main records to add. (Need more help? Get support.)

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

If you have a SharePoint Online Public Website, you can set it up to use your custom domain for the website URL address, like www.your_domain.com.

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 Dynadot by using this link. You'll be prompted to sign in first.

    Dynadot-BP-Configure-1-1

  2. Under Manage, choose the name of the domain that you want to edit.

    Dynadot-BP-Configure-1-2

  3. In the Name Servers row, choose your domain_name.

    Dynadot-BP-Configure-1-3

  4. In the Domain Record (required) section, find the boxes for the new record, and then type or copy and paste the values from the following table.

    (Choose the Record Type value from the drop-down list.)

    Record Type

    IP Address or Target Host

    TXT

    MS=msXXXXXXXX

    Note   This is an example. Use your specific Destination or Points to Address value here, from the table in Office 365.
    How do I find this?

    Dynadot-BP-Verify-1-1

  5. Choose Save DNS.

    (You may have to scroll down.)

    Dynadot-BP-Verify-1-2

  6. Wait a few minutes before you continue, so that the record you just created can update across the Internet.

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. Go to the manage domains page.

  2. On the manage domains page, select the domain that you are verifying and then, in the Action column for that domain, choose Start setup.

    O365-BP-Verify-1-2

  3. On the Add this TXT record to show you own domain_name page, choose Okay, I've added the record.

    O365-BP-Verify-1-3

  4. Choose Next.

Add a TXT record for SPF to help prevent email spam

  You cannot have more than one TXT record for SPF for a domain. (If your domain has more than one SPF record, it may result in email errors, as well as delivery and spam classification issues.) If you already have an SPF record for your domain, then add the required Office 365 values to the current record so that you have a single SPF record that includes both sets of values. Need examples? Check out these details and sample SPF records. To validate your SPF record, you can use one of these SPF validation tools.

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