After exporting emails, how can I view or remove pending export requests?

Use `Get-MailboxExportRequest` to list all export requests. To remove a specific request, use `Remove-MailboxExportRequest -Identity 'user\MailboxExport' -Confirm:$false`. To remove all requests, use `Get-MailboxExportRequest | Remove-MailboxExportRequest -Confirm:$false`. Requests are automatically retained for 30 days by default, but you can override this with the `-CompletedRequestAgeLimit 0` parameter when creating the export.
