调研方向
未指定源文件或测试。首先使用访客用户刷新的 token 重现 /shares/{share-id}/driveItem 请求，然后将其与 /me 以及 SharePoint Web UI 的访问进行比较，并以链接的 SharePoint issue 作为上下文。完成的要求是：针对反复出现的 401 响应，记录其原因并验证解决方案。

描述
Refernce similar to this in Sharepoint: https://github.com/OneDrive/onedrive-api-docs/issues/1039
Pattern of failure:
Initial API calls fail with 401
After manually visiting the file through SharePoint web UI, API calls work temporarily (1-4 hours)
API calls then fail again after a period of inactivity
Web UI access requires device code authentication flow
What works:
✅ Basic Microsoft Graph calls (/me) succeed
✅ Accessing files through SharePoint web UI works
✅ Token refresh succeeds and produces valid access tokens
What fails:
❌ Microsoft Graph API calls to /shares/{share-id}/driveItem
Issue Type: Microsoft Graph API Authentication
Affected Service: SharePoint Online for Business
User Type: Guest User (External/Cross-Tenant)
Authentication Method: OAuth 2.0 with Refresh Token
API Endpoint: /shares/{share-id}/driveItem
Problem Description:
As a guest user in your tenant, I am unable to programmatically access shared files via the Microsoft Graph API, despite having:
Valid authentication tokens
Proper API permissions granted
Ability to access the same files through the web UI
Detailed Symptoms:
API calls fail with 401 error:
{
"error": {
"code": "accessDenied",
"message": "There has been an error authenticating the request."
}
}
