I have two almost identical systems one at home and one at work. At home I am running version 1.0. I am able by accessing Tools... Account Settings... Server Options... to set messages to be left on the server until I delete them. That way we are able to view the same files both at the office and home until they are deleted.

The problem is that the system at the office is newer and I assume would be running a later version of Thunderbird and there does not seem to be a box or check box to set the messages to be left on the server.

How do you set the server option on later versions of Thunderbird...

Thanks
