Shared sub folders

[amariepsu]

One of my co-workers is sharing a subfolder with his manager, but when he
opens an unread e-mail or tries to delete it, it still shows as unread in the
manager's subfolder.

He wants to be able to work on the task requested in the e-mail, and then
have it automatically update as read, or have it deleted simultaneously in
both his, and his manager's folder. How do we get it to work?

how do you set up a co-worker being able to view and open a subfolder
