Hi Luis,
I have solved my problem.
Went to Tools/Trust Center/Add ons, at the bottom there is a blue arrow
clicked on this and then pressed up. It brought me up a list of 4 items. I
turned them all off (unticked them) and then tried my emails again. The
attachments opened. Then it was trial and error which one was blocked it,
turned them off & on in turn see which one prevented it. Ended up it was the
Symantec Antivirus Protection one.
Hopefully this will help you out too.

As has been said countless times in this newsgroup, do not install the ail
scanning feature of any AV program. It causes more problems that it cures.

I had a similar problem in outlook 2003 - but I did not have Norton installed
and the Add-on Names did not look like they were associated with my Virus
protection.
I disabled all of the add-ons and I was then able to read email attached.
I think it may be a corrupt add-on or one that was written for Outlook
before one of the "Security Updates". I would advise removing them all first
to see if any are causing the problem.
PS: the ability to read was affected by an automated update. I had
previously been able to read emails as attachments, then I was not able to. I
do not know when as I do not typically get forwards in this manner (about 1
every 6 months so ...).

That's a symptom of Google Desktop Search. Do you have that installed?
