My Outlook calendar won't display the events on the daily or weekly calendar. The event shows up in the side bar but NOT on the main calendar.

This is a personal M365 on a Mac.

Please advise

    Hi @Danielle Whitmore

    Since the event appears in the sidebar but not in the main calendar, please first sign in to Outlook.com Calendar using a browser and check whether the same event appears there.

    • If the event displays correctly on the web: the Outlook for Mac cache may be out of sync. In Outlook, select Tools > Accounts, choose the account, select Manage, and then Reset Account. Outlook will download the synchronized data again. Please note that locally stored information not yet synchronized may be removed. Clear the cache in Outlook for Mac
    • If the event is also missing from the web calendar: please confirm which calendar the event was saved to and whether it belongs to another connected account.

    Also, please let us know your Outlook version and whether the missing items affect all events or only specific ones.
