The error message you're encountering indicates that you are experiencing authorization issues while trying to synchronize a SharePoint calendar with your Outlook desktop. To resolve this problem, you can follow these steps:
Verify your permissions: Ensure that you have the necessary permissions to access and synchronize the SharePoint calendar. Check with your SharePoint site administrator or IT department to confirm that you have the appropriate rights.
Check SharePoint calendar permissions: Make sure that the SharePoint calendar itself has the correct permissions configured. Verify that you have at least "Read" access to the calendar. The site administrator or owner can check and adjust the permissions settings for the calendar.

Select each entry related to SharePoint or Office 365 and click "Remove" or "Remove from vault."
Restart your computer and try synchronizing the SharePoint calendar with Outlook again.
