PowerShell scripts for Exchange Online reports

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
Get-MailTrafficReport -Direction Inbound -StartDate 06/13/2019 -EndDate 06/15/2019

This cmdlet lists all the Microsoft 365 mailboxes in the organization.

SendAs permission report

This cmdlet shows which users have SendAs permissions configured.

Mail traffic report

Get-MailTrafficReport -Direction Inbound -StartDate 05/15/2019 -EndDate 05/30/2019

This cmdlet retrieves statistics on all incoming messages between May 15, 2019 and May 15, 2019.

Get-MailTrafficReport -StartDate 05/15/2019 -EndDate 05/15/2019 -Direction Outbound | Format-Table Domain, Date,EventType,Action,MessageCount

Mailbox size report

Get-MailboxStatistics -Identity John

This cmdlet retrieves the size of the mailbox owned by the user John, the number of messages it contains, and the last time it was accessed.

M365 Manager Plus' preconfigured reports

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.

M365 Manager Plus, our Microsoft 365 reporting, auditing, monitoring, and management tool, comes with over 700 preconfigured reports on Exchange Online, Azure AD, Skype for Business, OneDrive for Business, Yammer, and other Microsoft 365 services.
