Export Public Folder to PST: Methods, Steps, and Technical Guide

When Companies Export Their Data to PST Files

Moving to Another Provider

Companies may export Public Folder data to PST when moving from one email provider to another. This helps them preserve important emails and shared information before switching to a new environment and reducing infrastructure costs.

Preserving Important Data

Companies may export Public Folder data to PST before making major changes to their Exchange environment. This creates a separate copy of important emails and shared information that can be stored for future access.

Reducing Infrastructure Costs

Organizations may switch to a more affordable email system when the expenses associated with hardware and maintenance get higher. The process of exporting Exchange Public Folders to PST can secure all important email messages and shared information before the migration to a new environment.

What Data Can You Export Exchange Public Folders to PST?

Here is the list of data that companies usually export from Public Folders for backup, migration, or future access: 

Data Type	What It Contains
Emails	Messages, replies, forwards, and attachments are stored in Public Folders.
Contacts	Names, email addresses, phone numbers, and other contact details.
Calendar Items	Shared appointments, meetings, events, and related details.
Notes	Shared notes and other text-based information stored in Public Folders.
Tasks	Shared tasks, due dates, status, and task-related information.
Other Items	Other supported Exchange items are stored within Public Folders.

 

Manual Methods to Export Public Folder to Outlook PST

The following manual methods can be used by organizations and IT professionals to export Public Folder data to Outlook PST files without third-party software. With the required technical knowledge, they can use the built-in Outlook and Exchange options.

1. Export Public Folder to PST Using Outlook

Outlook allows users to export a PST file using its built-in import and export options. This method works well for smaller exports where users manually select the required folders and data. It is a direct option when you only need to export a few folders without using additional software.

Steps to export Exchange public folders to PST Using Outlook:

1. On your system, open Outlook and click File from the menu. Then, click Open & Export.
2. Choose the Import/Export option.
3. Select the Export to a file option, then click Next.
4. Choose Outlook Data File (.pst), then click Next.
5. Select the Public Folders that are required to export, then click Next.
6. Go to the location as needed to save the PST file. Select the option to handle duplicate items, then click Finish.
7. Once the Public Folders are exported, go to the location to find the saved PST file.

This method works for users who are familiar with Outlook, but it takes more time when exporting large Public Folders or working with accounts that are not fully synchronized.

2. Export Exchange Public Folders to PST Using PowerShell

PowerShell provides Exchange administrators with commands to manage and monitor Public Folder migrations. It can be useful for handling large environments and migration tasks, but exporting Public Folder data directly to PST requires additional methods or tools.

Steps to Export Public Folders to PST Using PowerShell:

1. First, assign the required Mailbox Import Export role to the administrator by running the following command:

New-ManagementRoleAssignment –Role “Mailbox Import Export” –User “Administrator”

 

2. Run the following command to export the Public Folder mailbox data to a PST file:

New-MailboxExportRequest -Mailbox “PublicFolderMailbox” -FilePath “\\Server\PSTs\PublicFolder.pst”

 

3. After the export starts, use the following command to check its status:

Get-MailboxExportRequest | Get-MailboxExportRequestStatistics

 

Export Public Folder to Outlook PST Manual Methods Limitations

• Large PST files can be an issue: Microsoft recommends keeping PST files below 50 GB, which is the maximum supported size for current Outlook versions. Larger exports may need to be divided into multiple PST files.
• A UNC network share is required: Exchange mailbox exports need a UNC path to save the PST file. The Exchange Trusted Subsystem must also have the required Read/Write permissions on the shared location.
• The right role is required: The Mailbox Import Export role must be assigned before creating a mailbox export request. This role is not assigned to role groups by default.
• Large exports can take time: The export time depends on the amount of data, network conditions, and MRS throttling. Large Public Folder exports can therefore take several hours to complete.
• PST is not the preferred migration method: Microsoft recommends using batch migration when moving Public Folders to Microsoft 365. PST-based migration can also cause Public Folder mailboxes to grow quickly during the process.
• The Exchange setup matters: The available export method depends on the Exchange Server version and how the Public Folders are stored. Modern Exchange uses Public Folder mailboxes, while older versions may use a legacy Public Folder database.
