I have windows 8.1 and windows mail. Until circa 5 weeks ago, when viewing my incoming mail, if I deleted an email it immediately disappeared from the viewing pane and from the in box listing. For the last 5 weeks if I delete an email it remains in the in box and viewing pane until such time as I come out of mail and then go back in again, When I do this the mails I deleted have gone. Can anyone advise why windows mail has stopped removing deleted emails from display, when deleted, and only when closing and re-opening mail. Many thanks.
