List of Microsoft / Office 365 IP ranges
My organization uses the Office 365 mail scanning service, but we also use a phishing simulation service to do phishing tests on our employees. Office 365 is creating a lot of false positives, so we wish to block the Microsoft IPs on the phishing service itself, but I can't find an up-to-date list of IPs anywhere.
I did see this article, but the IPs I needed to block were not in here: https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide
Is there another place I should be looking?
According to Microsoft, we need to take care both IPs and FQDN for whitelisting or bypass handling
