If you have a custom domain powering your blog (say, for example) and you’d like to have an email address that is customized for that domain (like you can create this type of email address using Microsoft Office 365. We’ll show you how.

Create an Office 365 Account

First, you’ll need to create an account by going to and sign up for the Small Business plan or higher to be able to use their business email service.

Add Your Domain Name to Office 365

Once you’ve logged in to your Microsoft account, you need to tell Office 365 which domain you want to use for your email. To do this, click the Domains option from the Admin menu inside your Office 365 account.


From there, you’ll be able to enter your domain name into the text box provided and click the Next button to continue.


Once you’ve done that you’ll be given asked to verify your domain using a TXT record.

Verify Your Domain Name

The first step is to confirm that you own the domain name you’re trying to use for your email.
You’ll see that you are provided a TXT record type or the MX record type. We only need to use one of these to verify the domain name, so we’ll go ahead and use TXT.

Copy the value from of the record (MS=XXXXX) so we have it in our clipboard.

Back in, Go to My Site → Domains and click on the relevant domain. Then click Name Servers and DNS → DNS Records and add a new TXT record with the value copied from Office 365.


Back in the Office 365 Admin screen, we’ll see a button which says Verify. When we click this button Office 365 will check your domain to see if it’s been verified.

It can take a little while before Office 365 is able to find the record to verify your domain so don’t worry if it doesn’t find it right away. Go and grab yourself a cup of tea and try again in 15-30 minutes. You can try again in 15-30 minutes when the record has had time to update.

Set Up Your Online Services

The third step of Office 365′ setup wizard is to set up your online services. The first option requires you to change the name server records at your domain registrar, which is We don’t want to do this, because it means your custom domain name will no longer work with your blog.

Instead, we need to choose the second option to manage your own DNS. Click Next after choosing this option to continue.


Remember when we added a TXT record earlier? Here, you’ll be doing something similar. The next screen, titled Update DNS settings, will give you several DNS records, which you’ll need to enter in your account, under My Site → Domains.

Set Up Custom DNS

In this step we’ll update our DNS records back at your dashboard so that you can start sending and receiving emails in Office 365 from your custom domain email address.

On this screen you’ll see a lot of complicated looking records. Don’t worry, it’s really easy to add these to your DNS records.

Let’s start at the top with MX record. We can see it has a Priority of 0 and a Points to Address value that includes our custom domain name.


Let’s copy that value to our clipboard and head back to our DNS editor in the dashboard.

Select MX from the drop down and leave the first text box empty.  Paste the value you copied into the second box and then put 0 in the priority box. Click Add New DNS record to add the record.


Back on the DNS records page at Office 365 we have several CNAME records to add. The first one has the Host Name oalled autodiscover. We can copy the Points to Address value and add another entry to the editor back at


Choose CNAME from the drop down and in the first box enter the hostname, which was autodiscover. In the second box, paste the value you copied and click Add New DNS Record to add this record in.


There are 5 more CNAME records which we can copy over in exactly the same way.

Now we’ve done all of the CNAMES we have one TXT record left and two SRV records. Let’s copy the TXT value first since we already did one back earlier.


Choose TXT from the drop down, then paste your value into the second text box, clicking Add New DNS Record to complete the entry.


The last records we need to add are the SRV values. These are a little more complicated since we have a lot more values to work with.

Let’s take the top record first and work through it step by step.


Choose SRV from the drop down and leave the first text box blank. In the Service box, enter the value sip and choose the TLS protocol from the drop down menu. Fill in the Priority value of 100 and Weight value of 1. Enter the Target Host value and Target Port number of 443 in the last two fields. Click Add New DNS Record to complete the entry.


Now we can go ahead and tackle the second SRV record using the exact same format. To finish our DNS record off, we just need to go back to the Office 365 page, click Verify.

Office 365 will check the updated records and let you know which records if any, haven’t been found yet.


These records will take a few minutes to update and in some cases they can take up to 72 hours to completely update. Perhaps have another cup of tea while you wait?

You can click Verify again to check whether the records have now been updated.

When the records have successfully been updated, you’ll see a confirmation message on the screen which says that from now on any emails sent to addresses using your custom domain name will arrive in your Office 365 account.

Just click Finish and then you’ll be all done completing the setup of your custom domain email.
