Outbound Messages

This page provides a snapshot of the rate of messages going out of your Exchange network. Outbound messages are messages that your Hub or Edge Transport servers receive via remote procedure call (RPC) and then send via SMTP. The dashboard uses Message Tracking logs to present this data.

The page has line charts that display both outgoing message rate (in messages per minute) and volume (in kilobytes per second).

It also has panels that display the top remote IP addresses and domains, as well as the top senders by message count and volume.

How to use this page

• If you click on a node in either of the line charts, the Splunk App for Microsoft Exchange brings up the base search that produced the events at that point in time, along with the events that occurred at that point.
• To learn about the activity of a top remote IP address, click the IP address's name in the "Top Remote IPs" list. The Splunk App for Microsoft Exchange loads the "Message Activity by IP Address" page for the selected IP address.
• To learn about the activity of a top remote domain, click the domain's name in the "Top Remote Domains" list. The Splunk App for Microsoft Exchange loads the "Message Activity by Domain" page for the selected domain.
• To learn about the activity of a top sender, click the recipient's name in the "Top Senders by Message Count" or "Top Senders by Volume" list. The Splunk App for Microsoft Exchange loads the "Message Activity by User" page for the selected user.
