Troubleshooting: Unblock URLs required for CRM Online

Microsoft Dynamics CRM Online uses several Microsoft URLs to help provide security, services, and features. However, your computer or your organization’s computer network may block access to some of these URLs. Blocking any of the required URLs will cause Microsoft Dynamics CRM Online to operate incorrectly or not at all.

You may see a network or server error message if your computer or your organization's network blocks the URLs you need. The error message might look like one of these:

  • "The specified Microsoft Dynamics CRM Server address (URL) is not responding. Ask your administrator to verify that the server is turned on, and then try again."

  • "There is a problem communicating with the Microsoft Dynamics CRM Server. The server might be unavailable."

You can unblock these URLs on your computer by adding them to a list of approved sites in your browser.

ImportantImportant
If the following procedure doesn’t unblock the URLs required for Microsoft Dynamics CRM, ask your system administrator to unblock the URLs on the organization’s network.

  1. On the Explorer bar, click or tap the Tools icon (the white gear shape), and then click or tap Internet options.

  2. Click or tap the Security tab > Trusted sites > Sites.

  3. In Add this website to the zone, type the URL for your CRM Online organization. For example, https://contoso.crm.dynamics.com

  4. Click or tap Add > Close > OK.

For a list of other URLs you may need to add to unblock, see Internet accessible URLs required for Microsoft Dynamics CRM 2011 or 2013 and connectivity
