Hi IBN,
Good day! Welcome to Q&A forum.
From your description, the user deleted a file in one of SPO site on 14th March 2025, however, cannot find it from the first and second recycle bin.
In SharePoint Online, items are retained for 93 days from the time you delete them from their original location. They stay in the site Recycle (first stage recycle bin) the entire time, unless someone deletes them from there or empties that Recycle Bin. In that case, the items go to the site collection Recycle Bin (second stage recycle bin), where they stay for the remainder of the 93 days unless:
· The site collection Recycle Bin exceeds its quota and starts purging the oldest items.
· The items are manually deleted by the site collection administrator from the site collection Recycle Bin
If you cannot find the deleted files in the second stage recycle bin (Files exceed retention time or are manually deleted), then the file is permanently deleted and cannot be recovered.
This is a guide on how to recover deleted files for your reference:

Alternatively, you can use the PowerShell command to recover deleted files.
