    Calendar app shows duplicate events


    I've been experiencing a problem with the Windows 10 Calendar app - it shows duplicate events.
    I'm using a Microsoft account (Outlook.com) and have it configured on the computer. Mail app Works ok and syncs. Calendar App shows duplicate events. If I access the same calendar on Outlook.com the calendar shows OK with no duplicates. On another computer with the same Setup the calendar does not show duplicates, Works as expected so this seems a problem confined to this one computer only.

    This Windows 10 instalation is about a month old (installed from scratch - no upgrade from 8) and has all published MS updates instaled and also all app updates.

    Have tried to uninstall the Calendar app, rebooted, reinstall the app, but duplicates persist.

    Any ideas? Thank you.

    Hello and welcome

    Is every event duplicated or just some of them? I have a few duplicated that are usually related to things like birthdays where I have multiple entries for the same person which I have never bothered to sort out but think it comes from the outlook birthday calendar.

    Just some of the events get duplicated. But only envents form the main calendar, can't recognize a pattern, neither recurrent nor otherwise. The events are not birthdays, just "normal" events on the main calendar.
