This script exports the email aliases in $export_names to a file with a yyyymmdd date stamp.

The BadItemLimit is jacked really high because when a mailbox is 24+ GB and has a lot of weird Chinese and other character sets that make the export think it's corrupt.

I'm finding I like powershell.

$export_date = $(get-date -f 'yyyymmdd')

$export_location = "\\servername\mailbox_exports\"

$export_names = @("jamesm", "ruperts", "mandyb")

ForEach($name in $export_names) {
	New-MailboxExportRequest -Mailbox $name  -FilePath ($export_location + $name + $export_date + ".pst") -BadItemLimit 1000 -AcceptLargeDataLoss
}
