Hello,
our Exchange acts strange when it comes to attachments. The behavior seems to be random. Sometimes in OWA and Outlook the attachment icon is not visible but the attchment is in fact there because when this mesage is forwarded it appears again and in Exchange message has the right size. One of the attachments is PDF si it has nothing to do with DAT files which was my first suggestion. Can anyone help? Thank you.
Pete
