Had a new PC set up with MS Office 2013 programs.  Outlook 2013 Word and Excel attachments do not open.  Program opens, but to a blank screen.  This includes my attachments created on the same computer.  Boxes in "Trust Center" are unchecked.  Problem persists.  It is possible to save the attachment, then open Word or Excel and see the saved file, but this is time consuming and annoying.  Outlook 2013 should just open its attachments from the message without a thousand extra steps.  Thank you.

I recommend that you post this in the Outlook Forum:  http://social.technet.microsoft.com/Forums/en-US/outlook/threads

Hi Gish,

Thank you for your question.

Did this issue occur in OWA?

We could open outlook->File->option->Trust Center ->Microsoft Outlook Trust Center->Trust Center Setting->Attachment Handing->Attachment and Document Preview

Then we make sure all option have check. And didnt uncheck Turn off Attachment Preview, or rebuild the profile to check if the issue persist.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Jim
