Using the Exchange Online Message Trace API
January 22 saw the announcement of the beta version of an Exchange Online Graph-based message trace API. The API can retrieve message trace records and their details and offers equivalent functionality to the message trace cmdlets in the Exchange Online management PowerShell module. However, sometimes applications simply want to access data without going through a module, and that’s what this API delivers. The article includes a complete PowerShell script to demonstrate how to use the API. https://office365itpros.com/2026/01/27/message-trace-api/How to Analyze User Email Traffic by Internal or External Destination
After writing a previous article about using PowerShell to analyze message trace data, I was asked about analyzing user (or mailbox) sending patterns to discover who’s sending email and where they’re sending messages to. As in many similar situations, PowerShell is a great tool to use because of its flexibility. This article explains how to generate a per-mailbox report of how many messages are sent and the percentage of internal versus external, plus the external domains the email goes to. https://office365itpros.com/2023/09/26/message-trace-user-analysis/
Applied Transport Rules name not displayed on Message Tracking Logs
Hi, I changed transport rule's configuration. Then, I tested some pattern of test that sending and receiving mails. I want to check if transport rule I changed is applied to mails, but there is not displayed the transport rule's name on message tracking logs. There displayed just like '550 5.2.1 Message deleted by the transport rules agent' instead of the transport rule's name. Not displayed details too. Is that displayed if over time? Also, could you tell me how to check applied transport rule's name in other way? I tried to use below commands but not displayed. Get-MailDetailTransportRuleReport GetMessageTraceDetail Thanks
