Before adding a domain to Azure ensure that the DNS Records are configured correctly, and have propagated. Click below to view the current DNS Records, where new domains should be pointed to.

Login to portal.azure.com (You need Administrator permissions to view this page).

You should see a row of labelled icons, click on App Services.

From here navigate to guestdiary-webbuilder-2 > Custom domains (preview).

Then click the button, Add custom domain.

In the panel to add a custom domain, choose these options:

Now you can enter the new domain, first without www, and click Validate.

If you get an error here, it is most likely because the DNS Records have not propagated yet, or they are not configured correctly. If it validates without any issues, go ahead and click Add.

Azure will begin the process of adding that. Meanwhile you can add the www version of the domain.

Click the button Add custom domain again, and select the same settings as before. This time, enter the domain with www at the beginning. Try again to Validate, and Add the domain, same as before.

And that's it! You can click the little bell icon in the top right of the screen to see how it's getting on. It will usually complete within 2-3 minutes.

If the domain has been added to Azure successfully, but you're still not seeing the website appearing at the domain you've added, make sure the domain has been added in the webbuilder itself!

To do this login to myguestdiary.com, and navigate to the property. Then in the left menu, go to Website > Settings. Here you'll be able to see a list of Website Addresses. Make sure the domain is added here, both with and without www, and then drag one of those domains to the top of the list (usually the www version).

Now that you've added the domain to Azure, you can add an SSL Certificate to it. View the article below on how to do that.
