I have been fooling around with this minor problem on and off for weeks. I am using Windows 10 and Office 2013. My Outloook file shows that I have 13,000 emails. That goes back 2 years and is far more than I need to have load every day. Outlook frequently asks me if I want it to perform an Auto Archive. I tell it yes every time. Nothing indicates that it has done anything even 24 hours later. I noticed that about 90% of the emails shows UNREAD. That is not true, but thinking that Windows needed to see read emails I tagged them all READ. I manually ran Auto Archive. Next day? Same 13k emails showing. Any clues to assist me?
