A Microsoft file hosting and synchronization service.
Hi, I'm John! I will help you with this.
Just to clarify, are the files not syncing from the PC to the iPhone/iPad, or from the iPhone/iPad back to the PC?
Also, are you signed into the same Microsoft account on all devices?
On the PC, check if the OneDrive app shows a sync error. You can click the OneDrive cloud icon near the clock and see if it says "Sync pending," "Not signed in," or any error message.
On the iPhone/iPad:
- Open the OneDrive app > Tap your profile picture > Confirm the same account is signed in
- Check if Camera Upload or Files On-Demand is enabled
To help narrow down the issue further:
- Is this a personal Microsoft account or work/school account?
- Are the files visible on OneDrive online at https://onedrive.live.com ?
- Did this start recently after an update or password change?
If possible, share a screenshot of the sync error message. Please blur any personal info.
