I had configured thunderbird on 4 pc which is connected direct from my mail server and email account on all are same. All things are working fine except on one pc thundirbird. I have 4 pc one of them create mail and save in draft folder(which is on the mail server) all of pc or thunderbird get that mail in draft folder from mail server. But only one thundirbird not updating it shows that there is mail on draft but after like changes have been made on another computer it doesn't show the changes still show the last created draft.
