Microsoft attack simulation training Landing page can't load

Question

Dear Microsoft Support Team,

We have been testing the Microsoft Attack Simulation Training feature and encountered an issue during the simulation. Specifically, when we attempt to access the Landing Page via the link generated in the simulation, the page fails to load properly.

Interestingly, when we access the same link using a network that bypasses our firewall, the Landing Page loads without any issues. This leads us to believe that our firewall may be blocking necessary resources or domains required for the Landing Page to function correctly.

Could you please advise us on:

• What URLs, IP ranges, or domains we need to allow through our firewall to ensure the Microsoft Landing Page templates work as intended?
• Are there any specific ports or protocols that need to be opened?

Your guidance would be greatly appreciated so we can proceed with our internal security awareness training smoothly.
