Report the Renaming Issue to OneDrive Support

Since there is no built-in app setting to prevent this automatic file renaming, contacting support is the recommended way to request assistance and log the issue.

During the camera-roll backup process on iOS, OneDrive automatically renames image files to a timestamp format ending in _iOS.jpg. Because Microsoft does not currently provide an option to toggle this off within the mobile app, escalating your feedback to the development team via official support is the most effective approach.

Understanding the Timestamp Origin: The date and time used in the new OneDrive filename are generated based on the server's time at the moment of upload, rather than the local time the photo was originally captured on your device.

Frequently Asked Questions

Can I turn off the automatic renaming of photos in OneDrive for iOS?

Currently, OneDrive for iOS does not offer an internal app option or setting to prevent the app from automatically renaming photos during the camera-roll backup process.

Why does the timestamp on my renamed OneDrive photo differ from when the picture was taken?

The generated timestamp in the new filename is typically based on the Microsoft server's date and time when the file is processed for upload, rather than the local time the photo was captured on your iPhone.

What information should I include when emailing OneDrive support about this renaming behavior?

You should include exact examples of the original filename (e.g., IMG_3950.jpg) and the renamed file, your specific iPhone device model, iOS version, the OneDrive app version, and the dates of the uploads.
