Pinnin Folder List

[Louise]

Does anyone know how to "pin" the folder list so that
when you open an email to read it, the folder list
remains on the screen? Any help is appreciated.

I've tried that. Buy when you open a message it takes up
the entire screen. I'm looking to have the message open
on the right side of the screen and still have the folder
list visible on the left. Thanks for your help.
