Using OE version 2, Tried to put the Store Folder and WAB for one computer on another Lan computer. When I try to make the change, the choice is grayed out. There is a way to do this using a Register change on xp, but it's not available when starting from Win7. Any ideas?

You can change mail storage and wab paths using the new tray icon menu:

But i would not suggest using a network path instead of local path.
And that, because problems may occur, like if network folder is not connected and you open oe, it will create new mail folders to default path.
Also the speed will be slower because network drives speed is much slower that local hdd's.
