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.
