When export an Exchange Online mailbox to PST is a different thing. The New-MailboxExportRequest<\/b><\/a> cmdlet is available for Exchange Server. But it isn’t the standard PST export method for Exchange Online. For Microsoft 365 mailboxes, administrators can use Microsoft Purview eDiscovery or Outlook-based export methods, it depends on the mailbox & export requirements.<\/span><\/p>\n

So you’re stuck with Purview eDiscovery, Outlook manual export, or PowerShell wrapping the same Purview backend. If you’ve already tried those, you know the pain. If you haven’t, here’s the short version: they’re built for legal investigation, not IT operations.<\/span><\/p>\n
