Get a latest delta token:\n   ```\n   GET /drives/{drive-id}/root/delta?token=latest\n   Headers: Prefer: deltashowremovedasdeleted, deltatraversepermissiongaps, deltashowsharingchanges\n   ```\n\n2. Share a file located inside a folder hierarchy (e.g., `root/folder/sub-folder/sample.jpg`) with a specific user.\n\n3. Query delta with the token from step 1:\n   ```\n   GET /drives/{drive-id}/root/delta?token={token}\n   Headers: Prefer: deltashowremovedasdeleted, deltatraversepermissiongaps, deltashowsharingchanges\n   ```\n\n## Actual result\n\nThe response contains 4 items. Only the file has `@microsoft.graph.sharedChanged`, the parent folders do not:\n\n```\nFOLDER root       — @microsoft.graph.sharedChanged: NOT PRESENT\nFOLDER folder     — @microsoft.graph.sharedChanged: NOT PRESENT, shared: {scope: users}\nFOLDER sub-folder — @microsoft.graph.sharedChanged: NOT PRESENT\nFILE   sample.jpg — @microsoft.graph.sharedChanged: true, shared: {scope: users}\n```\n\n## Expected result\n\nPer the documentation:\n\n> \"all items that appear in the delta query response due to permission changes have the @microsoft.graph.sharedChanged: True OData annotation\"\n\nParent folders that appear as hierarchy context (not due to their own permission change) should either:\n- Have `@microsoft.graph.sharedChanged` set when they are **directly** shared, OR\n- Be excluded from the response when they are only hierarchy context\n\nCurrently, folders **never** receive the annotation regardless of whether they were directly shared or appear as parent hierarchy. **This makes it impossible to distinguish parent folder noise from real folder permission changes.**\n\n## Additional testing\n\nTested all header combinations against the same delta token:\n\n| Headers | Result |\n|---|---|\n| deltashowremovedasdeleted, deltatraversepermissiongaps, deltashowsharingchanges | 4 items, annotation only on file |\n| Same + hierarchicalsharing | Identical 4 items |\n| Same + deltaExcludeParent: true | Identical 4 items |\n| Only deltashowsharingchanges | Identical 4 items |\n| No Prefer headers | 0 items |\n\n## Environment\n\n- API version: v1.0\n- Authentication: Application permissions (client credentials)\n- Service: SharePoint Online","author":{"url":"https://github.com/o-shevchenko","@type":"Person","name":"o-shevchenko"},"datePublished":"2026-02-18T18:12:47Z","url":"https://github.com/microsoftgraph/msgraph-sdk-java/issues/2548"}
