@kala cheng

First of all, the PST file size must be larger than the mailbox. Even if you export an empty mailbox, you can see that the PST file size is not 0, because the file structure takes up some space.

About the recoverable items, you could use "-ExcludeDumpster" to bypass them when create export request:

For more detailed information about it, you could have a look about this article: New-MailboxExportRequest

    So, first, it is required to grant the permission before starting the export process. In the below section, you will find a method to grant the permission first through the Exchange Admin Center. But, this method is only available till 2010 versions.

    1. To start the process, go to the Permissions then click on the Admin Roles.
    2. Now, open the Recipient Management properties of the group to give the Mailbox Import Export permissions. After that, go to the Roles option and select the Mailbox Import Export role and Add role.
    3. Now Login again to view the changed settings and Now Select the Mailbox, you want to move.
    4. Finally, right click on the user Mailbox and select option “Export to PST File after that then you can export your recoverable files to the PST format.
    5. Provide the Destination Path, of Share Folder to save the resulted PST File.

    Regards,
    William

    Hi @kala cheng ,

    If you use the Exchange Management Shell for exporting, you can select folders to export.

    New-MailboxExportRequest -Name "Kathleen Reiter Export" -Mailbox kreiter -FilePath "\SERVER01\PSTFiles\Kathleen Reiter.pst" -IsArchive -IncludeFolders "#Inbox#" -Priority High

    You can also reduce the size of mailbox by using the mailbox cleanup tool.
