    Troubleshoot Outlook Calendar sync

    Events added in Zoho Calendar are not syncing to Outlook Calendar

    When creating an event in Zoho Calendar, make sure you select Outlook Calendar from the Calendar drop-down in the Create Event window. Events added to a different calendar will not sync to Outlook. There may also be a short delay before the event appears — refresh the calendar after a few minutes.

    Clicking Outlook Calendar sync does not start the sync

    This usually happens when your browser is blocking pop-ups. Enable pop-ups for Zoho Calendar in your browser settings, then try clicking Outlook Calendar sync again. Enter your credentials in the authentication window to complete the setup.

    Account sync has expired

    If your Outlook account sync has expired because your Outlook account password was changed, re-authenticate your account to restore synchronization.
