Change of outbound IP addresses
The outbound IP addresses of the EU Hub can dynamically change when Microsoft renews key major components within their infrastructure. Neither EMVO nor SSR have any control over this activity.
For this reason, all OBPs have been previously advised to use and reference European Hub end point URLs instead of absolute IP addresses.
Please review your internal set up and ensure that should an outbound IP address change, you will not be adversely affected.
