Hi, @Santiago Marín
I’m afraid I have some bad news. Since the photos were deleted around May and they are no longer in the OneDrive Recycle Bin, they are already outside OneDrive’s normal recovery period.
For a personal Microsoft account, deleted files are normally kept in the OneDrive Recycle Bin for 30 days. "Restore your OneDrive" can also only go back within the last 30 days.
If the photos were permanently deleted from OneDrive after that period, unfortunately Microsoft cannot restore them.
The only remaining possibility would be if another copy still exists somewhere else, such as an old phone, another computer, an external drive, or another backup.
I know that’s not the answer you were hoping for, especially with photos that important to you.
Thanks!
