In MS Exchange 2003 I have a public folder discussion with an excel attachment. The public folder is shared with three people. I am a publishing editor and one of the other users is the owner. The title of the document is MayerAccount. When I open the attachement through the dicussion for the first time it names the document MayerAccount (1). Lately, when I open the attachment it says MayerAccount(13). It jumped from 6, 7, 10, 12 to now 13. I'm wondering if my computer is keeping an instance of the spreadsheet open even after I close it? I am sure to close the spreadsheet and the discussion to save changes for the other users to see each time I modify the spreadsheet but when I open it again, the number keeps rising. Is it something I am doing?
