A Microsoft file hosting and synchronization service.
Hello, thank you for reaching out to Microsoft Q&A.
Deleted files from your PC’s local drive are moved to the Recycle Bin on your desktop, while files deleted from OneDrive are moved to the OneDrive Recycle Bin.
In OneDrive, items in the Recycle Bin are automatically deleted after 30 days. Even with an active Office 365 subscription, you can restore OneDrive files only within that 30-day period. Since it has already been two to three months, OneDrive restore will no longer help here.
** If this is a work or school account, there may be a possibility of recovering the files for up to 93 days. However, this does not apply to personal Microsoft accounts.+*
In this situation, you can check the Recycle Bin on Windows to see whether the photos can be restored. You may also try a third-party file recovery tool to recover deleted files from your device and see if it helps.
