I have been using Office Outlook 2013 Pro for my email client very successfully for perhaps eight or more years and it stores all of those emails I wished to keep over that time. Two days ago the programme closed down after a few seconds and has continued to do so since then. I have been onto various forums etc and have followed just about every piece of advice available - sadly nothing has worked and I cannot access historical and important messages. Any and all advice will be received with enthusiasm and gratitude ! Bill S.
