CodeTwo services endpoints and IP addresses

This article lists all IP addresses used by CodeTwo Email Signatures for Office 365 (CodeTwo Email Azure Service). If your organization uses an endpoint security mechanism (endpoint filtering) that blocks or allows specific endpoints (such as URLs, IP addresses, port numbers, etc.), be sure to allow traffic on the addresses specified below. 

Below you can find the IP addresses of CodeTwo Email Azure Service regions.

Important: We don't recommend using IP addresses listed below in any third-party service (e.g. endpoint security mechanism or smart host). These IPs are updated frequently, so use them only if necessary and make sure to keep your configuration up to date with the addresses provided here. Otherwise, your mail flow may be affected.
