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'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:

This is how your records should look like:




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:



Once you've done so, press Save All Changes in both sections.

Then, please make sure to verify the changes in Microsoft365 Admin center by selecting "Verify". It typically takes around 30 minutes for record changes to take effect, but sometimes it can take a bit longer.

Give it some time and a few tries to pick up the change.

That's it!
