To ensure that all simulated phishing emails actually reach their intended recipients, advanced delivery must be set up in Microsoft 365 Defender. Doing so only takes a few minutes and we have prepared a step-by-step guide to make things easy for you.
-
Log in to your Microsoft Defender with an administrator account.
-
Expand the Email & collaboration menu, select Policies & rules, and then choose Threat policies.
-
Under Rules, select Advanced delivery.
-
Here, first select the tab called Phishing simulation and then select Edit. A new window titled Edit third party phishing simulations will open.
-
In the corresponding fields, enter the whitelisting information provided in the SoSafe Manager (Settings / Whitelisting) as follows:
-
The domains provided under Envelope sender addresses (technical senders) belong in Sending Domain on the Microsoft page. Note that only the domain, the part after the @ (name@domain.com), should be added here, not the entire address.
-
The IPv4 addresses provided under SoSafe mail servers belongs in Sending IP on the Microsoft page.
-
Simulation URLs don’t need to be configured here, as this setting only applies to non-email simulations.
-
Select Save to finish the process. It may take some time for the changes to take effect.
