A shared-library restore that omits recent work needs an evidence-based diagnosis, not a longer imaginary restore window. Audit logs, recycle bins and document versions serve different purposes. Changing one does not recreate missing file data in another.
Confirm the operation and its scope
Record the SharePoint site and library URL, the selected recovery activity and the time the operation ran. Ask whether someone restored a single version, used library restoration, recovered deleted items or invoked a separate backup product. “We restored OneDrive” is not specific enough to explain the result.
Ask contributors to preserve local work and avoid further changes to affected files. Keep independent copies of useful current documents before another operation. Recovery should have a named owner who can reconcile different reports about the same file.
Check available content before changing settings
For an existing document, open its version history and inspect candidates containing the missing change. For an absent item, search the original library and its deleted items. Note moved, renamed or re-uploaded files, because a matching filename alone does not establish continuity with the original.
If the desired work is found, recover only that document when possible. If the current file contains useful later edits, preserve it and arrange a reviewed reconciliation rather than silently replacing it.
Investigate the library restore result
The built-in library recovery uses version history and the recycle bin. Inspect any generated restore log for failed items. Re-uploading a file after deletion is a documented case in which that item’s restore operation can be skipped.
If the restore option is unavailable, ask the site administrator to check permissions and the library experience. Do not enable an undocumented “Document Library Folders” feature or modify tenant-wide settings to make the menu appear.
Separate the recovery window from retention
Do not run Set-SPOTenant -RestoreDuration: this is not a documented parameter for extending library restoration. Audit-log retention does not extend the built-in rollback window to 93 or 180 days. Logs may help establish what happened, but they are not the missing document’s contents.
Have the administrator inspect actual version-history configuration and approved backups. Avoid reducing history or assuming that changing its limits now can recover versions already removed.
Close with verified outcomes
For each outstanding file, record the source checked, candidate chosen and content reviewer. Share specific errors and paths with support rather than repeatedly rolling the entire library backward. A useful final record distinguishes an exact recovered revision from a reconstructed document and an unresolved loss, so colleagues know which result they can safely rely on.
