Hello. I would like to be able to select what program like windows
media player or nero player to use when opening my attachments in
outlook 2003, Were do I go to find it. Many Thanks. Terry.

Outlook uses whatever is set up as a Windows file association....this isn't
an Outlook issue. Change the file associations you wish - go to control
panel, folder options, file types. If you're saying you want to switch 'on
the fly' you won't be able to do that - you'd need to save the attachment,
and then use "open with" in the context menu when you right click on it.
