Why does Microsoft Dynamics CRM Online require access to https://www.crmdyntint.com?

andrew.punnett asked:

The list of “Internet accessible URLs required for connectivity to Microsoft Dynamics CRM Online” is comprised almost entirely of Microsoft owned domains.

However, I cannot understand why access to the URL https://www.crmdyntint.com is required. Visiting this URL with a web browser just displays a generic domain parking page with ads, which makes me worry about the security of the domain. According to a Whois lookup the domain is owned by a Hong Kong based firm named China Capital.

Does anyone know why access to https://www.crmdyntint.com is required by Microsoft Dynamics CRM?

My answer:

The list is probably outdated. That domain was just registered two weeks ago.

Creation Date: 2018-02-19T07:00:00.000Z

So it’s likely a previously expired domain that was used for something else.

The KB article was last updated almost a year ago.

Personally I would not bother to whitelist this URL.
