Inbound messages and Outbound messages reports in the new EAC in Exchange Online

The Inbound messages report and the Outbound messages report in the new Exchange admin center (new EAC) display information about email entering and leaving your organization. Specifically, the Inbound messages report shows information about email coming into your organization from the internet and over connectors. The Outbound messages report displays information about email leaving your organization to the internet and over connectors. Both reports also show the TLS encryption level that's being used.

Note

By default, the report shows data for the last 7 days. If the report is empty, try changing the date range.

  • Message volume: Shows the number of inbound or outbound messages to or from the internet and over connectors.

  • Messages by TLS used: Shows the TLS encryption level. If you hover over a specific color in the chart, you'll see the number of messages for that specific version of TLS.
