 ## Cause 2: Firewall blocking connectivity
 
-If you use Dynamics 365 (online) with Exchange on-premises, ensure your firewall allows connectivity from the list of IP ranges documented in [Microsoft Dynamics CRM Online IP Address Ranges](https://support.microsoft.com/help/2728473) including the referenced [Azure IP Ranges](https://support.microsoft.com/topic/microsoft-dynamics-crm-online-ip-address-ranges-0b22a844-e61d-443b-482f-945de79f764d).

If the **Test & Enable Mailboxes** is successful for your mailboxes, you can disregard the results from the **Test Connection** dialog.
