Keep in mind... One source of confusion in previous versions of Exchange Server, as far as the message size limits are concerned, is that created by the content conversion process. Content conversion happens when Exchange converts an internet/MIME message into MAPI/Exchange format, and vice versa. Content conversion generally increases the message size - roughly by 30%. If you set a maximum message size of 10Mb., and wonder why a 9 Mb. attachment didn't make it through, consider the content conversion overhead, as also message headers (which are computed along with the DATA portion of the message to calculate the message size), and any actions taken by Transport Rules. :)
