Question details
The organization needs to determine how to recover attachments from a SharePoint list that were deleted without authorization after being stored for approximately two years.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Recovering unauthorized deletions of long-standing SharePoint list attachments.
- Observed behavior
- Attachments have disappeared from the SharePoint list and need to be restored to their original location for organizational use.
Ensure you have the appropriate site permissions, such as Site Owner or Member, to access the SharePoint Recycle Bin and Site Assets folder. If server-level recovery is required, you must have your Microsoft 365 administrator's contact information ready.
Check the SharePoint Recycle Bin and Site Assets
The first and most accessible method is to look for the deleted attachments in the SharePoint site's standard recovery areas.
When files or attachments are deleted in SharePoint, they are not immediately destroyed. Instead, they are moved to the site Recycle Bin where they can be restored by users with the right permissions.
Open your SharePoint site and click on 'Site Contents' in the left-hand navigation menu or from the gear icon (Settings).
Open the 'Site Assets' folder to verify if the attachment files were accidentally moved or are still stored there.
Go to the 'Recycle bin' (usually found in the site settings or left navigation panel) and search for the deleted attachments.
If the files are not found in the primary Recycle bin, scroll to the bottom of the page and click on the 'Second-stage recycle bin' link to check for permanently deleted items.
Select the missing attachment files by checking the boxes next to their names, and click the 'Restore' button to return them to their original location.
Request Server-Side Recovery via Microsoft 365 Admin
If the files are purged from both recycle bins, a Microsoft 365 administrator must request backend recovery directly from Microsoft.

Frequently Asked Questions
How long are deleted files kept in the SharePoint Recycle Bin?
Files deleted from a SharePoint site are typically kept in the Recycle Bin for a total of 93 days. This retention period covers both the first-stage and second-stage recycle bins combined.
Can I recover attachments if the 93-day recycle bin period has passed?
Once the 93-day retention period expires, files are purged from the standard recycle bins. However, Microsoft support may be able to perform a server-side restoration if an administrator opens a support ticket within an additional 14-day window after the permanent deletion.
Who can access the second-stage recycle bin in SharePoint?
Only Site Collection Administrators or users with Owner-level permissions can access, view, and restore items from the second-stage (or site collection) recycle bin.
