Create DNS records at Namecheap for Office 365

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

If Namecheap 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.

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

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.

Follow the steps below.

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

  9. 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. Choose Setup > Domains.

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

    Domain name selected in Office 365 Admin Center

  3. On the Setup page, choose Start setup.

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 Namecheap by using this link. You'll be prompted to Sign in and Continue.

  2. On the Landing page, under Account, select Domain List from the drop-down list.
