    Hi,

    ActivityMimeAttachment table does not store the file contents. For all emails, the attached file contents are stored into the Attachment table. You can see the attachmentid (Foreign Key of Attachment table) in the metadata of ActivityMimeAttachment entity : http://msdn.microsoft.com/en-us/library/gg327995.aspx

    All other attachments except Email Attachments are stored in annotation entity (AnnotationBase DB table) and the file contents are uploaded into the documentbody string attribute in Base64 string encoded format.

    Judging based on name, columns and a couple of quick queries, it is an out of the box table that stores meta information on file attachments for messages that isn't stored for a typical file record in the annotationbase record.
