joyce Bashed at the keyboard and said:
All of a sudden I'm unable to open any attachments. What
can I do to fix this problem in outlook?
I presume you are talking about "Outlook Express" if this is the case:
In Outlook Express go to Tools, Options, Security, and uncheck "Do not allow
attachments to be saved or opened that could potentially be a virus".

You may need to read this next bit also:
*Why some file types and not others*
That's a decision Microsoft has made.
Fortunately, if you disagree, it is possible to add or subtract file types
from the Internet Explorer unsafe file list.
In Control Panel, double-click the Folder Options icon.
On the File Types tab, scroll through the list and highlight the file type,
forexample PDF, and click Advanced.
Remove the tick in the box marked "Confirm open after download".
Now you can have Outlook Express disallowing access to potentially unsafe
files, but excluding Adobe's PDF files.
