If the user wants to export Office 365 online mailbox to PST for free, then using the eDiscovery PST Export is the only solution. Other methods are also there, which are technically sound solutions to export Outlook 365 mailboxes.

Those are:

Using the PowerShell command, the user can synchronise an Office 365 Outlook Online account with a desktop-based MS Outlook. And then using the Import / Export feature, one can export Office 365 emails to PST using Outlook.

Script delegation full access, Outlook Online binds to the delegated mailbox, and exports to PST. Technically very likely possible, but I think no one ever tried to do it. Well, after trying scripts, I found that it is quite complex to Export PST.

Note: There is no such PowerShell script available to directly export PST from Office 365. However, you can use PowerShell to Export Exchange On-Premise to PST.

Export an On-Premise Exchange Mailbox to PST Using PowerShell

Here’s a basic PowerShell script to export an on-premises Exchange mailbox to a PST file using the New-MailboxExportRequest cmdlet:

Step 1. Connect to Office 365 Exchange Online

Open PowerShell on your computer and run it as an administrator. Use the following command to connect to your Office 365 Exchange Online account:

   $UserCredential = Get-Credential

   Connect-ExchangeOnline -UserPrincipalName <UserPrincipalName> -UserCredential $UserCredential

   Note: Replace <UserPrincipalName> with the actual user’s principal name.

Step 2. Export the Mailbox to PST

Once you are connected, you can use the `New-MailboxExportRequest` cmdlet to export the mailbox to a PST file. Here’s an example command:

   New-MailboxExportRequest -Mailbox <MailboxName> -FilePath \\Server\SharedFolder\mailbox.pst

 Note: Replace <MailboxName> with the actual mailbox name and provide the appropriate file path for the PST file.

Step 3. Monitor Export Progress

You can use the Get-MailboxExportRequest cmdlet to monitor the progress of the export request:

   Get-MailboxExportRequest

Step 4. Remove the Export Request (Optional)

Once the export is complete, you can use the Remove-MailboxExportRequest cmdlet to remove the export request:

   Get-MailboxExportRequest | Remove-MailboxExportRequest

Note: Make sure to replace <UserPrincipalName> with the actual user’s principal name and `<MailboxName>` with the mailbox you want to export. Also, provide the appropriate file path for the PST file.

Remember that you need to have the necessary permissions and Exchange Online PowerShell modules set up on your system to run this script.

So, to make the task easy, the automated solution is recommended over other methods.

Using Outlook, you can export data into a PST. However, before you begin, you have to ensure a few things. There are a few prerequisites for this method.

In the very first step, you have to configure your Office 365 account with POP configuration in Outlook.

By default, Outlook is set to download email for the past 1 year. You can change this setting if you need to export all your Office 365 emails collectively. Open Outlook, click on Account Settings> Account Name and Sync Settings, and move the slider to All.

Step-by-Step Guide to Export Office 365 Mailbox Using Outlook

Step 5. Select the name of the email account to export, only a single account can be exported at a time. Make sure that the Include subfolders check box is selected. This ensures that everything in the account will be exported: Inbox, Calendar, Contacts, and Tasks. Choose Next.

Step 6. Click on the Browse button to specify the destination location to save the Outlook Data File (.pst). Enter the desired file name, and click on the OK button to continue.

Step 7. Click on the Finish button to export Office 365 mailbox to PST using Outlook.

Prima facie of this method seems simple, but there are various shortcomings of this method.  Some of them are as follows:

You must have the technical knowledge to configure your Office 365 email account in Outlook with POP configuration.

Additionally, you can only export a single account at a time; for multiple-user data export, this method is not practical.

It does not export metadata of mailbox items such as folder properties (views, permissions, and AutoArchive settings), message rules, and blocked sender lists.

For instance, if you’re using Cached Exchange Mode, then this method will only export the items in your current cache.
