I have Outlook Express 6 which often reports that "OE removed access
to the following unsafe attachments in your mail....."
When I know the attachmesnts are from a safe source how can I obtain
them?

Hi Geoff,

I had the same problem for awhile, which had me totally baffled. 
Here's how I finally solved it for myself:  In OE6, click on "Tools,"
then on "Options," and then on "Security."  There is a square check
box next to a rule that says, "Do not allow attachments to be saved or
opened that could potentially be a virus."  If that box is check,
uncheck it, close OE, then reopen it, and your problem should be
solved.

If this method works, and you would like to accept it as the answer to
your question, let me know and I will be glad to post it as the
answer.
If not, perhaps another Researcher will have something different for
you to try.  Good luck and best wishes,

Hi geoff57:

I had the same problem too a while back.  I used the method byrd has
suggested and it does in fact work.  This function on Outlook is sort
of a blessing and a curse.  While it does prevents malicious files
(containing viruses) from being downloaded via e-mail, it also keeps
out legitimate attachments.

It should be noted, that the disabling of the option will let virus
infected attachments onto your system.  These attachments should be
dealt with by a virus checker like (Norton Anti Virus or Macafee).

Hope this comment helps.

The method suggested by Byrd will enable you to open all attachments. 
It is also possible to enable opening only attachments with certain
file types, which may be a bit more secure.

Instructions (for Windows XP) adapted from
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q291387&:

Click Start, point to Settings (or click Control Panel), and then
click Control Panel (or switch to Classic View or View All Control
Panel Options).

Double-click Folder Options.

On the File Types tab, click to select the file type that you want to
allow, and then click Advanced.

Click to remove the check mark from the "Confirm open after download"
check box.
