External OneDrive items access

In Azure Portal (business account) we created an app for OneDrive files and folders management via Graph API and granted both delegated and application permissions for required actions (create folder, list folder, upload file, etc.).

In some cases we need to use application permissions for these. When we try to e.g. list the folder stored on the drive within the same Azure AD, they all succeed.

But we need the app to be used from the external accounts as well. When I try to list the folder on my personal drive I get following error:
"The provided drive id appears to be malformed, or does not represent a valid drive."
(using endpoint https://graph.microsoft.com/v1.0/drives/{drive-id}/items/root/children)

  • The drive ID is correct (returned from /me/drive endpoint while using delegated permissions)
  • The app was allowed to do all the stuff for my personal account
  • Permissions are configured (Directory.ReadWrite.All, Files.ReadWrite.All, Sites.ReadWrite.All, User.ReadWrite.All)
  • Supported account types are "Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox)"

Is there anything else where the app might be limited not to reach the external drive items? Or is the problem anywhere else?
Thank you for any advice!

    Hi @Martin Tomek
    To share the item with external users, you will need to learn about external sharing features of Microsoft. Please refer to following document
    https://learn.microsoft.com/en-us/sharepoint/external-sharing-overview
    After share the item with external users, you can access the item by the graph api 

    GET /shares/{shareIdOrEncodedSharingUrl}

    For more details you can refer to the following document
    https://learn.microsoft.com/en-us/graph/api/shares-get?view=graph-rest-1.0&tabs=http
