Hello!
This page http://technet.microsoft.com/library/dn635176%28v=exchg.150%29.aspx depicts a DLP template as a document that contains some definite word pattern (The patent template contains the blank fields “Patent title,” “Inventors,” and “Description” and descriptions for each of those fields—that’s the word pattern.), and any information ADDED to this pattern will be treated as "sensitive information".
"The patent template contains the blank fields “Patent title,” “Inventors,” and “Description” and descriptions for each of those fields—that’s the word pattern. When you upload the original patent template, it’s in one of the supported file types
and in plain text. The DLP agent uses an algorithm to convert this word pattern into a document fingerprint, which is a small Unicode XML file containing a unique hash value representing the original text, and the fingerprint is saved as a data classification
in Active Directory."
For the testing purposes I uploaded this template to my Exchange (Sensitive.docx):

Now I can't send ANY docx file in an attachment, not only the documents derived from this template - why?
Thank you in advance,
