MessageStats reports show the message values in two categories: logical and physical. In the report column headings, the term physical identifies the physical message counts. If messages are not labeled as physical, they are logical messages.
For example, in the Mailbox Activity | Summary report, the message columns are labeled as Physical Messages. The term physical message is used to provide message counts in a manner similar to how Exchange handles a message. When a user opens Outlook, creates a message with five recipients and clicks Send, there is one physical message that Exchange tries deliver to each recipient.
Exchange may create copies of the message so that each recipient can receive the message. This process is called bifurcation and is performed when different recipients receive copies of the same message. A logical message is a message in which each recipient is counted as a separate message. For example, if a mail message is created in Outlook and is sent to nine recipients, MessageStats would count that as one physical sent message and nine logical sent messages. From a delivery standpoint (received messages), the logical and physical counts are the same since a delivery event can only happen to one mailbox.
For information about internal and external messages, see How Does MessageStats Determine Internal and External Messages? .
Here are the standard reports (using the tree node names) that show physical message counts:
