Command Line Parameter Changes in Outlook

As part of SP3 for Outlook 2003 (and included in SP1 for Outlook 2007) we’ve made a change to the way command line parameters are parsed to ensure Outlook is always doing the right thing. As part of this change, a less common way of attaching files to new e-mail messages through command line parameters with Outlook may be broken in some solutions.

Previously, Outlook under some circumstances would handle an implicit command line parameter without a switch. For example, if a command line argument was provided without a switch, and was a path to a folder in the file system, Outlook would treat the argument with an implicit /select switch flag, displaying that folder in the Explorer window. If the argument was a path to a file on the file system, Outlook would use an implicit /a switch and attach the file to a new message.
