I'm trying to fathom out why folders keep vanishing in Windows Mail on\nVista Home Premium.\n\nThere are three email accounts in use. One uses the normal Inbox and\nfolders have been created for the other two, to serve as their own\n'Inboxes' with message rules set up to direct appropriate incoming mail\ninto them. So far so good and it all works fine. But after a few weeks,\nthose folders disappear along with all the mail they contained. There's\nno sign of them in the Deleted Items or any other folder and they're\nnowhere to be found on the computer, nor any of the emails they contained.\n\nThis has happened at least three times now and although I've set it up\nagain and it's working, I fully expect the folders to vanish again in\nthe next several weeks! Needless to say, it's causing considerable\nannoyance to the people concerned that so much email keeps getting lost.\n\nIs this known to happen with Windows Mail? Other than reverting to\nhaving all email in the regular Inbox, which they really don't want,\nwould anyone have any suggestions that might help?
