Measures reported by EXOTranRuleTest

You can use mail flow rules (also known as transport rules) to identify and take action on messages that flow through your Office 365 organization. Mail flow rules are similar to the Inbox rules that are available in Outlook and Outlook on the web. The main difference is mail flow rules take action on messages while they're in transit, and not after the message is delivered to the mailbox. Mail flow rules contain a richer set of conditions, exceptions, and actions, which provides you with the flexibility to implement many types of messaging policies.

A mail flow rule is made of conditions, exceptions, actions, and properties:

  • Conditions: Conditions identify the messages that you want to apply the actions to.

  • Exceptions: Exceptions, optionally identify the messages that the actions shouldn't apply to.

  • Actions: Actions specify what to do to messages that match the conditions in the rule, and don't match any of the exceptions.

  • Properties: Properties specify other rules settings that aren't conditions, exceptions or actions. For example, when the rule should be applied, whether to enforce or test the rule, and the time period when the rule is active.

All messages that flow through your organization are evaluated against the enabled mail flow rules in your organization. To know whether any of these messages match a configured rule, and if so, which rule it is, use the EXOTranRuleTest test. This test evaluates incoming and outgoing messages against configured transport rules, and reports the count of messages that conform to any of the rules. Detailed diagnostics of the test reveal which messages match which rule and what action has been taken on such messages. This enables administrators to review and evaluate their rule and action configurations, and figure out if rules need to be fine-tuned.

Outputs of the test : One set of results for each event type related to transport rules.

First-level descriptor: Event type

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Total_hit Indicates the number of messages that conform to transport rules. Number The value of this measure is a sum of the values of the Inbound rule hits and Outbound rule hits measures.
Inbound_rule Indicates the number of incoming messages that conform to transport rules. Number Use the detailed diagnosis of this measure to know which incoming messages matched which rule and what action was taken on them.
Outbound_rule Indicates the number of outgoing messages that conform to transport rules. Number Use the detailed diagnosis of this measure to know which outgoing messages matched which rule and what action was taken on them.
Unique_senders Indicates the total number of unique senders of messages that match one/more transport rules. Number  
Unique_receivers Indicates the number of unique recipients of messages that match one/more transport rules. Number
