Trying to open an attachment in Outlook 2000 causes Explorer to open in the c:\winnt\system32 folder

Posted on 2005-05-10

I have a user that regularly receives an attachment from one of our clients.  It is a PDF and is always has the same filename.  He has had no problem opening this in the past.  All of a sudden, when he tries to open (or save) the attachment, instead of Acrobat Reader starting, Windows Explorer starts, pointing to c:\winnt\system32.

Other attachments, including other PDFs can be opened and saved fine.  I have also seen this on another user that regularly received a CSV file that always had the same filename.  His problem was solved when he was upgraded to a new machine running Outlook 2003.

There is nothing wrong with the PDF that doesn't open, as I can forward it to myself and open it correctly, and as I mentioned, all other PDFs are working fine on his PC.

I believe this is a bug in Outlook 2000 and I think I have seen a KB article relating to it, but typically, I can't now find the article.

Any suggestions are appreciated.

    Check this:
    change the default temp folder that Outlook uses to save or open attachments. This is done via editing an entry in the registry.
    The default is stored under HKCU\Software\Microsoft\Office\x.0(based on what version you have)\Outlook\Security
    You then edit the string "OutlookSecureTempFolder". Default is C:\Documents And Settings\UserName\Local Settings\Temporary Internet Files\OLK##... I changed it to C:\Documents and Settings\UserName\Local Settings\Temp\, clicked OK, exited regedit and rebooted the computer. All attachments open without issue now.

    OK i'll try that.  I probably won't be able  to do it until tomorrow morning GMT.  I think I may have tried this on another user, but the reg key gets reset once the user logs back in.  If so, that's a policy or login script and is my problem so i'll still give you the points.

    Just for reference.  He receives this message when trying to save the attachment:

    'Cannot save the attachment.  Can't create file: Dawn Chorus.pdf.  Right-click the folder you want to create the file in, and then click Properties on the shortcut menu o check your permissions for the folder.'

    Needless to say, the permissions are perfectly OK.
