EPG flagged Microsoft Office 365 IPs - Add IPs to allow list

This article applies to the following products:

  • Messageware EPG 2019
  • Messageware EPG 2016
  • Messageware EPG 2013

Overview

Microsoft Office 365 utilizes a range of dynamic IP addresses that connect to data centers worldwide. Occasionally, these IPs may be flagged by Spamhaus or EPG.


Solution

To ensure uninterrupted connectivity, please add Microsoft IPs to EPG by following the steps below:

  • Navigate to EPG Admin

    • Click IP Filtering > Allow List, and add the relevant Microsoft IPs to ensure they are not blocked by security filters.
    • Make sure that the IP Allow list set to "Enabled"
    • Once the IPs are added, click Save

 

These are known Microsoft Office 365 IPs and can be safely whitelisted if mistakenly flagged.
