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

If Crazy Domains 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.)

• Add a TXT record for verification

• Add an MX record to route email

• Add six CNAME records

• Add a TXT record for SPF to help prevent email spam

• Add two SRV records

After you add these records at Crazy Domains, 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 Crazy Domains by using this link. You'll be prompted to log in first.

   

2. In the My Account section, choose Domains.

   

3. On the Domain Names page, in the Domain section, choose the name of the domain that you are updating.

   

4. In the DNS Settings section, choose the drop-down list icon.

   

5. Choose Add Record.

   

6. Choose TXT Record from the Add Record drop-down list.

   

7. Choose Add.

   

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

   Sub Domain	Text Record
   (Leave this field empty.)	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?

   

9. Choose Update.

   

10. 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 Domains page.

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

   

3. On the Setup page, choose Start setup.

   

4. On the Verify domain page, choose Verify.

   

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 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. Need examples? Check out these details and sample SPF records. To validate your SPF record, you can use one of these SPF validation tools.

2. In the My Account section, choose Domains.

   

3. On the Domain Names page, in the Domain section, choose the name of the domain that you are updating.

8. In the boxes for the new record, type or paste the values from the following table.

   Sub Domain	Text Record
   (Leave this field empty.)	v=spf1 include:spf.protection.outlook.com -all Note: We recommend copying and pasting this entry, so that all of the spacing stays correct.
