Corrupt Outgoing E-mail Attachments from within SageCRM

Outgoing e-mail attachments sent from within SageCRM are OCCASIONALLY corrupt when the recipient tries to view. It seems to be specifically with .doc & .docx (not PDF). If the same attachment is sent through Outlook (or anything but CRM), the attachment is not corrupt and is viewable. If I send the same attachment multiple times through CRM, that exact attachment will come through successful one time and corrupt another. Wondering if anybody else has ran into this? Any insight is appreciated. Thanks.
