Determine the Maximum Recipients per Message value.
Open the Exchange Management Shell and enter the following command:
Get-ReceiveConnector | Select Name, Identity, MaxRecipientsPerMessage
For each Receive connector, if the value of MaxRecipientsPerMessage is not set to 5000, this is a finding.
If the value of Maximum Recipients per Message is set to a value other than 5000 and has signoff and risk acceptance in the EDSP, this is not a finding.
