    Additionally, you can submit feedback by going to New Outlook (desktop app) > Help > Feedback, then choose the appropriate category and select Submit once ready.

    New Outlook does not support all the legacy SharePoint calendar integration features that Classic Outlook did, especially with older SharePoint environments. The available guidance in context focuses on Classic/Outlook 2016 behavior and fixes; it does not provide a supported method to make an “old SharePoint” calendar sync reliably with New Outlook.

    Where syncing is supported (Classic Outlook / Outlook 2016), issues are typically resolved by:

    • Applying the required Office updates (for example, the January 3, 2017 update for Outlook 2016 that fixes the “Unsupported server” error when syncing SharePoint calendars).
    • Avoiding unsupported scenarios such as recurring items sent via email into a SharePoint calendar, which cannot be synchronized to Outlook.

    For New Outlook specifically, context does not describe any supported configuration or workaround to enable full calendar sync with older SharePoint calendars. In practice, this usually means:

    • Use Classic Outlook to connect and sync with the old SharePoint calendar (via Connect to Outlook in SharePoint), or
    • Manage the calendar directly in SharePoint (web) instead of relying on New Outlook sync.

    If Classic Outlook is available in the environment, using it for this scenario is the only approach described in the provided material that supports SharePoint calendar synchronization.
