    Dear Clark Maisie,

    Based on your description, the error code 0x88ffc00a is commonly associated with a problem communicating with the OneDrive or SharePoint sharing service when attempting to share a file directly from an Office application.

    First, please try the following:

    1. Confirm that the workbook is saved in OneDrive or SharePoint Online.
    2. Close the workbook and navigate to the file in OneDrive or SharePoint.
    3. Try sharing the file directly from the file location.
    4. Perform an Online Repair of your Microsoft 365 installation and test again. For reference: Repair an Office application

    If the issue still persists, please let me know:

    1. Does the issue occur with one specific workbook in Excel or all Office files when you try to share them?
    2. Are you able to successfully share the same file directly from OneDrive/SharePoint on the web?
    3. What is your current Office version?
    4. If possible, please take a screenshot and share it with me.

    I look forward to your update. The additional information should help me identify the next troubleshooting steps.

    Thank you very much for your valuable time and your cooperation.
