Manage senders for impersonation protection license required and impact?
![](https://techprofile.blob.core.windows.net/images/WsWYoGdWukeBW66msAr6qQ.png?8D8128)
Does anyone know what the minimum license required to utilize the Manage senders for impersonation protection like below?
Because I have 300+ users to add, and not all of them using E3 or E5, some of them are using just F3 and E1 or Exchange P1 licenses.

Only the F3 or E3 license may not work.
You could refer to: Microsoft Defender for Office 365 security product overview
