Mailflow Receive Test - Exchange to ExO (Hybrid)

Summary

This monitor focuses on measuring the Quality of Service (QOS) of a hybrid Exchange deployment. The monitor implements an end-to-end functionality probe to verify mail flow between an OnPremise mailbox (Exchange Server) and an Exchange Online mailbox.

Metric value 0 indicates correct receipt of the test email. Metric value 1 indicates an error. If there is a failure, the metric options indicate the following details:

Reason, Exchange Online Database Name, Recipient, Sender User Name and GUID of email.

Metric requires other metrics of the group to run. Please see "Configuration"
