#在EXO中有Get-MailTrafficTopReport，官网： https://docs.microsoft.com/en-us/powershell/module/exchange/get-mailtraffictopreport?view=exchange-ps 这个report可以很直观的查处一定时间内每个邮箱的发送量，但是在本地Exchange服务器中却没有。

#以下脚本调用了Exchange服务器的get-messagetrackinglog，以及.count()方法，来拿到和EXO get-mailtraffictopreport一样的发送数据

#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

#以下是您本地Exchange服务器上配置的域名
$AcceptedDomains = @("speridian.com","truecoverage.com","sesameindia.com","speridiantec.onmicrosoft.com","finalign.com")
