Organizing and accessing contact information in Outlook.com
Hello, I am so glad I stumbled upon this thread! I am experiencing the same problem, and possibly worse than some. If I don't delete the duplicates every couple of days, they multiply to over 12,500, and I only have 140 contacts!
Brian Tillman, if you could PM me, perhaps you can connect me with the person/team that is investigating this, and I can contact them via internal channels? I can help troubleshoot it in real time, if they wish.
