In today’s world, cloud technology has become an essential part of any business’s digital infrastructure. As an experienced Cloud Architect, I understand the importance of efficiently managing data in cloud environments, and the associated risks of doing so. In this article, I aim to provide an overview of how to export mailboxes from Microsoft 365 to PST files using PowerShell.

Why Export Microsoft 365 Mailboxes to PST?

PST files are the most widely used data format for archiving and migrations, and can be used for a variety of tasks. PST files are also a great option for backing up data and exporting mailboxes from Microsoft 365. The process of exporting mailboxes to PST files is not only beneficial for archiving purposes, but can also help with litigation requirements, recovering lost emails, and transferring emails between accounts.

How to Export Microsoft 365 Mailboxes to PST with PowerShell

In this section, I will discuss the steps you can take to export mailboxes from Microsoft 365 to PST files using PowerShell.

Step 1: Run the Exchange Online PowerShell Module

The first step in the process is to run the Exchange Online PowerShell Module. To do this, you must run the following command:

Step 2: Create the PST File

The next step is to create the PST file. To do this, you must run the following command:

New-Item -Path -Name .pst -ItemType File

This command will export the mailbox to the PST file.

Step 4: Monitor the Export Process

The final step is to monitor the export process. To do this, you must run the following command:
