While using MS Outlook my system get restarted because of Outlook updating. After restarting the system, when I access MS Outlook latest version. I don’t understand what happened with my mail. Before updating, in my inbox mailbox, there were 2000+mails but after updating there are 4000+ mails. I was shocked how my mails get doubled. Every email is repeating means duplicate emails in Outlook. To fix this issue I searched on the internet and found few references which are helpful according to Outlook expert team.
