OK, here's what I think you mean,
click start/all programs
Move the mouse up to the Startup Folder and right click on it, and select
explore
Now leave that window temporarily and click start again, and move the cursor
up to outlook express, and right click and select copy, now move the mouse
to the explorer window which has the startup folder open, right click in it
and select paste.
You should now have created a shortcut to outlook express in the startup
folder.
Right click on the shortcut and select properties. Select the shortcut tab,
and click the arrow to the right of the run window and from the drop down
menu select Minimized.
That should do it.
