Simulate exactly who loses access before you reset permission inheritance — every name listed, guests first — and export the impact list before the reset will even run.
Inheritance365 and Unlock365 live inside the WhoHasAccess365 web part — shown here on a real SharePoint page.
Impact simulation lists every name, guests first
Export required before the reset is allowed to run at all
Includes bulk check-in for files left checked out by people who've gone
Every SharePoint call this tool's code makes — the same table checked by the build and by the verifier script in the download.
| Call | Method | Destructive? |
|---|---|---|
| …/lists(…)/items(…)/resetroleinheritance | POST | Gated behind exporting the impact simulation first |
| …/GetFileByServerRelativePath(…)/CheckIn(…) | POST | No — checks in or discards a checkout only |
Full cross-tool table and the shipped verifier script are on the main safety audit page.
