description Learn to verify your domain and set up DNS records for email, Teams, and other services at Namecheap for Microsoft.

Connect your DNS records at Namecheap to Microsoft 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, Microsoft Teams, and so on.

After you add these records at Namecheap, your domain will be set up to work with Microsoft 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 Microsoft, 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 Microsoft 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 Namecheap by using this link. You'll be prompted to Sign in and Continue.

    :::image type="content" source="../../media/1827f9fc-4dc9-4f9d-a392-7817c47b00b3.png" alt-text="Sign in to Namecheap.":::

  2. On the landing page, under Account, choose Domain List from the drop-down list.

    :::image type="content" source="../../media/3f457d64-4589-422c-ae34-fc24b0e819eb.png" alt-text="Select Domain List from the drop-down list.":::

  3. On the Domain List page, select the domain you want to edit, and then select Manage.

    :::image type="content" source="../../media/fb2020d8-707c-4148-835e-304ac6244d66.png" alt-text="Select Manage.":::

  4. Select Advanced DNS.

    :::image type="content" source="../../media/05a4f0b9-1d27-448e-9954-2b23304c5f65.png" alt-text="Select Advanced DNS.":::

  5. In the HOST RECORDS section, select ADD NEW RECORD.

    :::image type="content" source="../../media/8849abfe-deb6-4f6a-b56d-e69be9a28b0f.png" alt-text="Select ADD NEW RECORD.":::

  6. In the Type drop-down, select TXT Record.

    [!NOTE] The Type drop-down automatically appears when you select ADD NEW RECORD.

    :::image type="content" source="../../media/a5b40973-19b5-4c32-8e1b-1521aa971836.png" alt-text="Select TXT Record for the domain verification TXT record.":::

  7. In the boxes for the new record, type or copy and paste the values from the following table.

    (Choose the TTL value from the drop-down list.)

    Type Host Value TTL
    TXT @ MS=ms XXXXXXXX
    Note: This is an example. Use your specific Destination or Points to Address value here, from the table. How do I find this?    		 30 min

    :::image type="content" source="../../media/fe75c0fd-f85c-4bef-8068-edaf9779b7f1.png" alt-text="Copy and paste the values from the table for the domain verification TXT record.":::

  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 Microsoft and request the record. When Microsoft finds the correct TXT record, your domain is verified.

To verify the record in Microsoft 365:

  1. In the admin center, go to the Settings > Domains.

  2. On the Domains page, select the domain that you're verifying, and select Start setup.

    :::image type="content" source="../../media/dns-IONOS/IONOS-DomainConnects-2.png" alt-text="Select Start setup.":::

  3. Select Continue.

  4. On the Verify domain page, select Verify.

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 Microsoft. Instead, add the required Microsoft values to the current record so that you have a single SPF record that includes both sets of values.
