查询在邮箱上设置的转发功能：

Get-Mailbox -server MX01 -Filter {ForwardingAddress -like '*'} | Select-Object Name, ForwardingAddress | Export-Csv "D:\Scripts\Forwarding.csv"

查询在OUTLOOK信箱上设置的邮件规则转发：

Get-InboxRule -Mailbox "James Bond" | where {$_.RedirectTo} | fl MailboxOwnerID, RedirectTo

or

Get-InboxRule -Mailbox "James Bond" | where {$_.ForwardTo} | fl MailboxOwnerID, RedirectTo

检查所有邮箱中是否有设置转发/规则

脚本：

Set-AdServerSettings -ViewEntireForest $True

$mbxs = Get-Mailbox -server MX01 -ResultSize Unlimited

ForEach ($mbx in $mbxs){

Get-InboxRule -mailbox $mbx.primarySMTPAddress | where {$_.ForwardTo -or $_.RedirectTo} | fl MailboxOwnerID, ForwardTo, RedirectTo

}
