When users send signatures with a logo, the pictures get changed to: "<< OLE Object: Picture (Device Independent Bitmap) >>". Using exchange server 2008 and windows server 2008. I have not found this issue anywhere else.

Embedded pictures are removed as these can contain malware and might act as flags for Spam.http://www.techtalkz.com/microsoft-outlook/435052-screenshot-changed-text-ole-object-picture.htmlRaj

Hi, I agree with Rajnish. The Embedded pictures are removed and replaced as OLE Object: Picture (Device Independent Bitmap).
