Whatever the reason, exporting an Outlook 365 mailbox to PST is a pretty simple process. Here are a few different ways that you can export PST from Office 365:
Export Mailbox to PST From Office 365 – PowerShell Method
The PowerShell method is a command-line interface that offers more control over the entire process as compared to eDiscovery because it is a manual method. In addition, the eDiscovery PST export tool exports Office mailboxes in the .pst file format that is not supported by all email clients.
There are a few limitations to the PowerShell method:
-
- The PowerShell method only works for mailboxes that are less than 50 GB in size.
- You can only export one mailbox at a time using this method.
- This method can only be performed if you are an Office 365 administrator.
You can perform the following steps to export Office 365 mailboxes to PST using PowerShell:
1) First, click to open the Microsoft Exchange Management Shell.
2) After that, you need to connect to your Microsoft 365 organization by using the following command:
Connect-EXOPSSession
3) Now, you have to create a remote Mailbox Export Request by using New-MailboxExportRequest cmdlet as shown below:
New-MailboxExportRequest -Mailbox “Test Mailbox” -FilePath “\\SERVER01\PST\Testmailbox.pst”
4) Once the above command gets executed successfully, you will see a message that says, “The mailbox export request was created successfully.”
After this, you can check the status of your export request by using Get-MailboxExportRequest cmdlet as shown below:
Get-MailboxExportRequest
You will see a list of all running and completed export requests, as well as the export progress on the MS exchange server. If you want to check the status of a specific export request, you can use the following command:
Get-MailboxExportRequest -Identity “Mailbox Export Request” | Get-MailboxExportRequestStatistics

Office 365 Export PST File Size Limit
Office 365 is a powerful tool for businesses of all sizes, but one of its most useful features is the ability to export Office mailboxes to a PST file. This can be helpful when moving data to a new computer or backing up important files. It can also be helpful for those who need to migrate to protect their data integrity and safeguard against data loss and file corruption.
However, there is an intrinsic limit to the exported PST file size that can be exported from Office 365. The maximum size for an exported PST file is 50 GB. This limit applies to both free and paid versions of Office 365.
If you need to export more than 50 GB of data, you will need to split the PST file into multiple files. This can be done using a utility such as PST Splitter. Splitting a large PST file into multiple smaller files can make it easier to manage and transfer the data. It also helps to prevent problems with corruption or data loss.
To split a PST file, you will need to create a new PST file and then drag and drop the data from the old PST file into the new one. Once all of the data has been moved, you can delete the old PST file.
You can then export each of the smaller PST files from Office 365. This process can be repeated until all of the data has been exported.
