I recently installed 4 new PCs--all are Windows 8 professional. All 4 have Office 2013. Issue 1: users are getting duplicate emails. I think I have resolved this by unchecking "keep email on server for 14 days" in advanced settings section. They use POP email with their ISP (CenturyLink). Internet connections have been intermittent over the last 10 to 14 days, coinciding with the occurrence of this problem so I think this will minimize the issue--agree or disagree? They only have one email account, only one email address each.
Issue 2: This one I can't understand; Friday when they left they had minimal unread messages in their Inboxes--now this morning they have multiple folders with tons of unread messages, some going back to April 2013 and others as far back as 2012. Have no idea what can cause this--I do know if you import emails (which I did 2 weeks ago) you may get a bunch of emails showing up as unread but can't explain how Friday all is OK, then this morning hundreds of unread emails. Any ideas, suggestions? Thanks.
