There is a new IP address in use for our InboxCast service endpoint. The new IP address is 220.127.116.11
This new IP address was assigned by Microsoft's Azure without notice to our service. We apologize for any inconvenience this may cause.
If you are restricting access to your CRM by limiting the external endpoint IPs that can connect, you will need to update your firewall rules to permit this new IP address to have access inbound and outbound. (Please note that this new IP replaces the IP address 18.104.22.168.)
