Dear Tim,
I’m sorry to hear that you lost your photos. You can restore deleted files or folders in OneDrive by following these steps:
1) In the navigation pane, select Recycle bin.
2) Select the files or folders you want to restore by pointing to each item and clicking the circle check box that appears, and then click Restore. Tip: If you’re using OneDrive with your personal account, you can select Restore all items to restore everything in your recycle bin. This option isn’t available in your work or school OneDrive. (more on that here:
https://support.microsoft.com/en-us/office/rest...)
Deleted files remain in the OneDrive Recycle Bin for 30 days. So if you deleted them recently, you should be able to recover them.
You can also check your backup: If you have a backup of your OneDrive files or your device, check if you can restore your photos from there.
Best Regards,
George A.
