Email is the most used form of business communication. Important details like client information, project files, and transaction information are often exchanged via email, making employees’ mailboxes some of the most targeted entities by hackers. To ensure mailboxes are secure, IT admins often use PowerShell scripts to retrieve details on Exchange Online mailboxes, mail traffic, mailbox sizes, and more. Below are some PowerShell scripts used to get information on Exchange Online mailboxes.Inbound mail traffic report

It's true that PowerShell scripts can fetch data that the Microsoft 365 admin center cannot. However, as you can see in some of the examples above, the more granular the data you need is, the longer the PowerShell scripts get. IT admins have to take care of the code syntax, figure out which parameters to use, and verify the correctness of the code manually before executing it; this adds to operational overhead, requiring more work hours.
