【Exchange server】Get-MailTrafficTopReport

#在EXO中有Get-MailTrafficTopReport，官網： https://docs.microsoft.com/en-us/powershell/module/exchange/get-mailtraffictopreport?view=exchange-ps 這個report能夠很直觀的查處必定時間內每一個郵箱的發送量，可是在本地Exchange服務器中卻沒有。

#如下腳本調用了Exchange服務器的get-messagetrackinglog，以及.count()方法，來拿到和EXO get-mailtraffictopreport同樣的發送數據

#There is Get-MailTrafficTopReport in EXO, official website: https://docs.microsoft.com/en-us/powershell/module/exchange/get-mailtraffictopreport?view=exchange-ps This report can be intuitively investigated for a certain period of time The sending volume of each mailbox, but not in the local Exchange server.

#The following script calls the get-messagetrackinglog of the Exchange server and the .count() method to get the same sending data as EXO get-mailtraffictopreport

#The below parts needs to be your Exchange server accepted domains
#如下是您本地Exchange服務器上配置的域名
$AcceptedDomains = @("speridian.com","truecoverage.com","sesameindia.com","speridiantec.onmicrosoft.com","finalign.com")
#================================================
#No need to modify the below parts
#如下部分無需更改
