Setting up Office 365 with a Namecheap domain

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


1. Sign in to your Namecheap account.

2. Select Domain List from the left sidebar and click on the Manage button in front of your domain name:



3. Go to the Advanced DNS tab and click on the Add New Record button:



4. Here you will need to make the 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 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.
