Export all mailboxes from an Exchange Server, 5 at a time
Thanks to StackOverflow for some help with the logic on waiting for a job to finish
$mailboxes = Get-Mailbox
ForEach ($mailbox in $mailboxes){
$running = @(Get-Job | Where-Object { $_.State -eq 'Running' })
if ($running.Count -ge 8) {
#too many jobs, we'll wait for the first to complete
$running | Wait-Job -Any
}
#there weren't too many jobs, or a job just completed, let's go
Start-Job {
New-MailboxExportRequest -Mailbox $mailbox.Alias -FilePath "\\SERVER01\PSTFileShare\$($mailbox | select -Expand Alias)_Export.pst"
while ((get-mailboxexportrequest -mailbox $mailbox.Alias).Status -eq 'InProgress'){
"Mailbox export in progress, waiting"
start-sleep 60
}
}
#End of this Mailbox
}
#lets wait for everything to finish
Wait-Job * | out-null
# Process the results
foreach($job in Get-Job)
{
$result = Receive-Job $job
Write-Host $result
}
