#以下脚本可以使用PowerShell导出比较直观的快速报告，和GUI相似，适合服务器运维定期导出报告使用

#O365 There are two types of mail tracking reports:
#1. One is for quick reports (no delay in export), and the corresponding commands are get-messagetrace and get-messagetracedetail
#2. The second type is the delayed detail report (usually there is a 1 hour delay, but it will be more detailed), and the corresponding command is get-historicalsearch

#The following script can use PowerShell to export more intuitive and fast reports, similar to GUI, suitable for server operation and maintenance to export reports regularly
