Troubleshoot issues with verifying your custom domain in Office 365

Confirming to Office 365 that you own your domain can be challenging. There are lots of detailed steps to go through on several sites, and the DNS system is slow and nitpicky. If you’re having trouble getting past the domain ownership step, read on to see if the steps here help. (Why does Office 365 need to confirm that I own my domain?)

Office 365 can’t verify that I own my domain

What you see:

You’ve followed the steps in the portal to verify your domain, but you’re still getting an error message that Office 365 can’t confirm that you own your domain.

Why it happens:

This could be caused by any of several things:

Incorrect record.    The “verification” record you add has to match exactly what Office 365 is looking for. And because the DNS hosting websites where you add that information are often cluttered and hard to navigate, it can be tricky to get all the right info in the right places.

Time delays.    After you add the verification DNS records for your domain, it can take up to 72 hours for the new record to be “visible” to Office 365 because of the way the DNS system does updates. And if you realize there was a typo in the record and you go back to fix it, the new update can also take up to 72 hours to finish updating across the system.

Domain already used.    If you previously added your domain to another Office 365 offering and it hasn’t gotten removed completely, that can keep Office 365 from being able to add your domain and confirm that you own it.

What you can do:

Look at the DNS record for your domain.   Check that you've created the Office 365 DNS verification record correctly.

Make sure it’s been 72 hours.    It’s frustrating to have to wait so long after you’ve added the record, but DNS can be very slow to update across all the network servers. If it’s been more than 72 hours since you made changes and Office 365 still can’t verify your domain, try removing and adding the verification record again. You can follow the steps in the portal or check out the step-by-step instructions in Help for when Office 365 manages your DNS records or when you manage your DNS records at your DNS hosting provider.

Check the status of the domain in the portal.   

  1. Sign in to Office 365 with your work or school account.

  2. Go to the Manage domains page.

  3. If the Status column next to your domain shows any issues or incomplete setup, click the link in the Action column.

Make sure your domain name isn’t already being used.    For example, if you signed up for Office 365 Small Business and now want to use Office 365 Enterprise or Office 365 Midsize Business instead, your domain may still be set up with the Office 365 Small Business subscription. Check that subscription to make sure your domain has been removed, and then sign in to the new subscription and follow the steps in the portal to add your domain.

Check out the Office 365 Community.    If your domain ownership still isn’t squared away, try posting a question in the Office 365 community forums. They’re a great resource, including Microsoft support agents who can help if you’ve tried the steps here and are still stuck.
