While trying to back up emails I seem to have lost them. Following the HELP page in Mail (Mac OS X program) I moved the MAIL folder from LIBRARY to the desktop. I failed to press OPTION while I was doing this, as the HELP page advised. So now, in Mail the identifiers of the messages are there, but the messages aren't and an error message appears saying that the emails have not been downloaded from the server, that I need to be online, etc. I am on line, have done "get mail", all of the obvious things. I've tried to locate the original MAIL folder with Spotlight. The server is at verizon.net The MAIL folder has reappeared in LIBRARY, but it is empty. I'd be very grateful for any help or re-direction.
