New installs of Office 2000, Professional we find users cannot open Office attachments received in Outlook. If they save the document, open Word or Excel then they can open the document. This also occurs if they try to open a document from Explorer.
The error message they receive is “The system could not find the file specified.” At this point, Word or Excel will open in the background. If they click the attachment again it will open. The work around we have found is to keep Word or Excel open. Then everything will open on the first try. However, this is not the way it should work.
