Introduction

Managing junk email and safe sender settings is crucial for ensuring important emails don’t get lost in the spam folder. In Microsoft 365 Exchange Online, PowerShell can be a powerful tool to manage these settings. This guide walks you through how to fetch and update the Safe Senders list for a user using PowerShell. This tutorial is especially helpful for Microsoft 365 administrators who want to automate and manage user preferences.

Prerequisites

Before running these scripts, ensure you are connected to Exchange Online PowerShell. You can connect using the following command:

Script 1: Export Safe Senders List

This script extracts the Safe Sender list (also known as Trusted Senders and Domains) for a user.

PowerShell Script:

– Export-CSV : Saves the output to a CSV file for easy viewing.

Script 2: Add Safe Sender Email

Use this script to add a specific email address to a user’s Safe Senders list.
