Setting up Office 365 with Crucial Hosting

To make it easier to get in touch with us, from the 24th of March 2016 all support tickets will need to be submitted from your Crucial Control Panel.

As many customers advance their online presence, we have seen many of them utilize Office 365 for their email hosting. As a popular service, please see below for information as to how to setup Office 365 when hosting your website with Crucial.

Before you begin

Some important notes:

  1. Some of the DNS settings that you will need to setup are unique to you and Office 365 will tell you what the proper settings are. While the information on this page will serve as a generic guide, it will not be 100% accurate. Always refer to the details provided within your Office 365 administrator portal.

  2. If your DNS Nameservers are not Crucial's, these steps will not apply to you. To check this, begin by performing a whois lookup on your domain: (*.au only) (Global) (Global)

    And compare the nameservers to ours as listed here:

    If using Crucial's nameservers, the steps below will be applicable to you. Otherwise, the changes will need to be made on your DNS Nameserver host.

  3. Office 365 is a Microsoft service. We cannot and do not access, provide support for, or manage your Office 365 products or services. This information serves as a guide only.


Adding and Verifying Domain

First, log in to the Microsoft Office 365 Portal.

On the left-hand menu, click Domains.

Then, on the page, click Add Domain. If you've already attempted this before, and the domain is already listed, click the 'Start Setup' link beside it in the list.

On the Add a Domain page, follow the steps to add your domain. 

In either case, you will then be given a TXT record to setup the domain. At this point, you will want to open a new browser window/tab and navigate to your cPanel page. The easiest way to do this is to go to http://www.your.domain/cpanel

When logged in, locate the Advanced Zone Editor


Go back to Office 365 and take note of the TXT record to add. It will be something like: MS=ms12345678. This code is unique to you.

Then add the TXT Verification record into cPanel for your domain.

The record should appear in the list:

Finally, go back to Office 365, and click on the "Ok, I've added the record" link. This will check for the TXT record in order to verify the domain. It will advise when this was completed successfully.

Adding Office 365 Records

First, proceed through the Domain setup on Office 365. This involves setting up user accounts and addresses. When complete, Office 365 will take you to the third step.

Office 365 will eventually ask if you want to set up the DNS records for you. This involves changing your nameservers from Crucial's (or anyone elses) to Office 365. This may be a valid option for you, but this is outside the scope of this article.

Otherwise, select No, and click Next.

On the following screen, you can select which services you intend to use. At a minimum you'll likely only need the first option "Outlook on the web for email, calendar, and contacts". But if you want Skype for Business and Mobile Device Management, select those as well. Then click Next.

The following screen will display the records you need to add.

Return to your cPanel in the other browser window or tab. Access the Advanced Zone Editor once more.

Access the Advanced Zone Editor and add the CNAME and TXT records, as per the details given in Office 365.

Next, return to the Home page within cPanel, and then access the MX Entry page.

Then, add the MX Record as provided on the Office 365 portal. Do note that the MX record is unique to your domain.

Some important notes:

  • It is best to delete any other MX entries you have.
  • Under the Email Routing heading, ensure this option is set to Remote or Automatic.

When complete, the MX records should look like this:

Finally, you should now be able to go back to Office 365 and complete the setup by clicking "Okay, I've added the records". Office 365 will then check the records and inform you if successful. At this point, emails will now begin to be delivered to your Office 365-hosted service, and you will be ready to add your email accounts on your computers and devices.
