The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine whether the SMTP Archive Sink has been installed and enabled:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\ArchiveSink\1\Enable Smtp Messages

If the Exchange Server Analyzer finds that the value for Enable Smtp Messages is greater than 0, a non-default configuration message is displayed.

A value of 0 indicates that the SMTP Archive Sink is disabled. A value of 1 indicates that the SMTP Archive Sink is enabled. Values other than 0 or 1 are not supported.

The SMTP Archive Sink tool is a custom script that enables the archiving of all messages coming into and moving out of a specific folder on an Exchange server. By default, when SMTP Archive Sink is enabled, all messages and their recipients are archived to an .eml file, except for Bcc recipients.

By default, when you enable SMTP archiving with the SMTP Archive Sink, all messages submitted to transport by Simple Mail Transfer Protocol (SMTP), by the Exchange store, or by any other sinks trigger this event. Theoretically, this event can be raised one time for each message, and this event can be archived only one time. The OnMessageSubmission event is raised before the routing or categorizer events. Therefore, these messages are referred to as PreCat messages. By default, messages are archived for this event when the SMTP Archive Sink tool is installed. Messages that are archived for this event contain the prefix file name: ARCH_random number.xml.

If you do not want to archive messages on this Exchange computer, you can set the Enable Smtp Messages registry key to 0, or you can uninstall the SMTP Archive Sink. When you uninstall the SMTP Archive Sink, all registry keys used by SMTP Archive Sink are deleted.
