This event can be seen with Event ID 1084. There are several conditions under which this message can occur. For example, some third-party products can cause this message. One of the products is “Secrets for Windows,” which is a client-side encryption application. Basically, the message indicates that the PR_RTF_COMPRESSED property exists, but its size is smaller than the size of the header structure that the stream is supposed to begin with.
Check to see if there is a client-side application that could be manipulating the messages before they are processed by the server. Look for related messages in the application log. Check if there are server-side applications that are processing the mails (for example, an antivirus application).
