Corrupt Office 2007 Attachments
We use Symantec DLP (Vontu) 11 and a large portion of the Office 2007 attachments in our incidents are corrupt. They are of type docx, pptx, and xlsx, and when opened the following message appears: "The file name.xxxx cannot be opened because there are problems with the contents", followed by "The file is corrupt and cannot be opened" in the Details section. Even upon review of the incident it's obvious the file is corrupt without looking at the attachment because the Office 2007 file is detected as a Zip archive. No amount of file maintenance from the desktop can recover the file, so we assume it's a Vontu issue.
Has anyone experienced this issue and managed to resolve it?
