have you tried office diagnostics yet? That should be the first step.

does this happen for every attachment - from gif to jpg to pdf to word and
excel files or does it only happen with some file types?

Hi guys,

I have been unable to view attachments of any file type using Outlook 2007
on Vista Ultimate.

* When I try to view an attachment, for example a GIF file, I get a
message box saying "The operation Failed. An object could not be found."
* When I try to save the attachment, I get a message box saying "Cannot
save the attachment."
* When I try to "preview" the file, I get a page with a message saying
"This file cannot be previewed. Try opening the file in the program in
which it was created."

I can, however, view, preview and save the same files on Windows XP /
Office 2003. Is anyone able to shed any light on this please?
