Follow these instructions if you want Office 365 to manage your Office 365 DNS records for you.
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: 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.
To get started, go to your domains page in Domainnameshop by using this link. You'll be prompted to log in.
Choose My Domains.
Choose the domain that you want to edit.
Choose the DNS records tab.
Choose Show advanced settings.
In the boxes for the new record, type or copy and paste the values from the following table.
Note: This is an example. Use your specific Destination or Points to Address value here, from the table in Office 365.
Choose the + (Add) button.
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.
On the Domains page, choose the domain that you are verifying.
On the Setup page, choose Start setup.
On the Verify domain page, select Add a TXT record instead, and then choose Next.
Note: 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.
