This Exchange Server Database file (EDB) is composed of Private and Public folders. Private folders are mailboxes that contain system and user mailbox data. On the other hand, Public folders are used for sharing data with other users in your organization, through shared access to the Exchange data.

      Why Export Public Folders to PST?

      Public folders are critical for an organization when it comes to effectively storing, organizing, structuring, and sharing Exchange data between users. Public folders help users to share files and data with multiple users across the organization.

Thus, a regular backup of Public folders is needed to safeguard this data from any kind of corruption or data loss. As PST format is widely supported, you may use it for migration.

      1. Correct!

        New-MailboxExportRequest command doesn’t support public folders. My in-house admins are using Outlook’s Import/Export for exporting Exchange 2010 public folders.

      2. I am not comfortable with PowerShell queries. Is it possible to verify the performance of a software in the free demo?
