Guys wanted to let you know that I resolved this issue, the problem was in the PowerPoint setup, somehow I had a checkmark on Protected View within Trust Center. The checkmark was checked at Enable Protected View for Outlook Attachments.



I appreciated you guys response but finally I was able to resolved it. Honesly I don't know how that command had the checkmark.

Thanks to all,

Frank

Frank, Thanks, you saved me a lot of time. I also had a user that had the preview protect boxed checked in the trusted center.
