Hi Mary!Its a common problem after the last upgrade. Microsoft support advices to check the ost file for inconsistencies (read more info https://support.microsoft.com/en-us/help/2526306/synchronization-problems-occur-in-outlook-and-in-outlook-web-app ). But I also recommend you to think over using a 3-rd party tool for Outlook syncing. I am using AkrutoSync and Im very satisfied with it. The contacts sync automatically between PC and mobile as well as the other data. If interested read this http://www.akruto.com/sync-outlook-contacts-with-android/
