The call came in at 8:03 a.m. on a Monday. A paralegal had been reorganising a shared matter file library the previous afternoon and had accidentally bulk-deleted a folder containing 800 documents across 12 active client matters. The files were gone from the library. The partner handling the firm's largest active matter had a court filing deadline in 48 hours.
About the Organisation
Meridian Legal is a mid-sized law firm with 130 staff across three offices. Like many professional services firms that migrated to Microsoft 365 in recent years, their document management relies heavily on SharePoint Online. A central SharePoint site holds matter files, precedent libraries, and correspondence, organised by practice area and client reference.
IT is a two-person team. There is no dedicated SharePoint administrator. Natasha, the senior IT officer, manages Microsoft 365 alongside the firm's broader infrastructure. She was familiar with SharePoint but had never needed to perform a recovery of this scale under time pressure.
Why Native SharePoint Recovery Fell Short
The first instinct was the SharePoint recycle bin. Natasha logged into the affected site and opened the recycle bin view. The problem was immediately apparent: 800 deleted documents appeared as individual line items, mixed in with dozens of other recently deleted files and folders from unrelated activity in the same library. The native recycle bin has no way to filter by folder origin, deletion event, or batch operation. Sorting by "deleted date" helped narrow the list, but items deleted by the paralegal were interleaved with items deleted by other users that same afternoon.
Restoring 800 items individually was not viable. Even at 10 seconds per item - selecting, right-clicking, confirming - that would take over two hours and required perfect identification of which items belonged to which client matters.
The second option Natasha considered was PnP PowerShell. The module includes cmdlets for scripting batch restores from the recycle bin. But writing a reliable script from scratch under time pressure, against a production environment, carried real risk. A scripting error could restore files to the wrong location, create duplicates, or - in the worst case - trigger further deletions.
Microsoft support was the third option. SharePoint Online data recovery through a support ticket is possible in some scenarios, but it involves an unpredictable wait time and no guarantee of completeness. With a filing deadline 48 hours away, that was not an acceptable path.
How ShareMaster Solved It
Natasha had installed ShareMaster six months earlier for a storage cleanup project. She opened Recycle Master and connected to the affected site collection.
Recycle Master's indexed recycle bin view loaded all deleted items with their full metadata: original path, deleted by, deletion timestamp, and file size. Natasha applied two filters simultaneously. First, deletion date: yesterday between 2 p.m. and 5 p.m., the window when the paralegal was working. Second, original path: containing the folder name used for client matter files. The 800 documents appeared as a clean, filtered list, completely separated from everything else in the bin.
"I could see all 800 files in one view, sorted by original folder, with the deletion time confirmed. It took about three minutes to get to that point."
Natasha selected all 800 items and clicked Restore Selected. ShareMaster restored every file to its original location in the library, preserving the original folder structure. Every file landed in the right place, with no duplicates.
Total restore time: approximately 11 minutes.
By 9:20 a.m., the partner handling the urgent matter had confirmed that all documents were back and intact in the correct folder. The filing deadline was never at risk.
After the Incident
Once the immediate recovery was complete, Natasha took two follow-up actions.
She used Report Master to export a permission matrix for the affected library, showing every user's access level. The audit revealed that several paralegals had been granted Contribute access - which includes the ability to delete files - when they only needed Read or Edit. Natasha tightened permissions across the affected library and two similar libraries in the same site.
Meridian Legal also formalised a short protocol: any bulk deletion of more than 20 items in a matter library now requires a second confirmation from the IT team before proceeding. The SharePoint library was configured to require check-out before editing, adding a further friction point for accidental bulk operations.
What This Scenario Illustrates
Accidental bulk deletions are one of the most common SharePoint incidents in professional services firms. They happen during matter file reorganisations, end-of-year archiving, library restructuring, and migrations. SharePoint Online's 93-day recycle bin window means the data is almost always recoverable - but the speed of that recovery depends entirely on how quickly you can identify and isolate the right items.
The native recycle bin is adequate for restoring a handful of specific files when you know exactly what you are looking for. It is inadequate for bulk recovery scenarios where items need to be identified by path, actor, or time window rather than by name.
The difference between a 90-minute resolution and a half-day incident - or an unrecoverable one - is the ability to search and filter the recycle bin with precision. For a step-by-step walkthrough of the recovery process, see the guide to recovering deleted SharePoint files.
