Setting up Office 365 with a Namecheap domain

The option to use a custom domain name with Office 365 is only available for Office business packages.

To map your Namecheap domain with an Office 365 account, you need to do the following:

1. Go to Office 365 Admin center.

2. Mouse over to the App Launcher icon and select Admin from the list:





3. Click on the Setup option on the left and hit the Start Setup button:





4. Click on the Let's get started link:





5. Insert your domain name in the format domain.tld and click Next:





6. Copy TXT Value generated for your domain (MS=ms53476746 in our case):





 7. Go to your Namecheap account to set it:

- select Domain List from the left sidebar and click on the Manage button next to your domain:





- go to the Advanced DNS tab and click on the Add New Record button:





- select TXT Record for Type, insert @ for Host and paste a verification string for Value:





- use the Save All Changes button.Wait about 30 minutes for the newly created record to be accepted globally and get back to your Office account to proceed further with the setup:





If the setup is successful, you will be able to add new users who will use Office 365. Just put in the First and Last name into the corresponding fields along with the email address:





Choose the option you need on the next screen and click on the Next button:





Select the No, I have an existing website or prefer to manage my own DNS records option and click Next:





Here are the records required to use Outlook for email, calendar and contacts:





To add them for your domain, get back to your Namecheap account and make necessary changes in the Host Records and Mail Settings sections.

In the Host Records section, you will need to add the following ones:

In the Mail Settings section, select the Custom MX option and create the record for @ Host pointing to [yourdomain-tld].mail.protection.outlook.com (nctest-info.mail.protection.outlook.com in our case)  with 0 Priority.

This is how your records should look like:





Once you've done so, press Save All Changes in both sections and go back to your Office account in several minutes to confirm this change by clicking on Okay, I've added the records link.


Congratulations! The domain name is now associated with Office 365:







That's it!
