File won't transfer from PC to phone

Check the OneDrive storage for the same personal Microsoft account used by Phone Link, because the “15 GB” you checked may be Google Drive or a different Microsoft account.

1. Check the account used for the transfer

1. On the PC, open Phone Link → Settings → Account and note the Microsoft account.
2. On the iPhone, open OneDrive, select the profile icon, and compare the signed-in account.
3. If they differ, add or switch to the Phone Link account and check its storage.
4. Open OneDrive once to force synchronization, then retry with one small file.

Phone Link for iPhone does not support work/school accounts, so this must be a personal Microsoft account.^1^ If that account has exceeded its Microsoft storage allowance, OneDrive cannot upload or synchronize new files.^2^

Since the account you already checked has plenty of space, do not delete files unless it turns out to be the account actually used by Phone Link.

2. Update Phone Link and retry through Start

1. On the PC, open Phone Link → Settings → About → Check for updates.
2. Install any update, close Phone Link, and reopen it.
3. Open Start, select the connected iPhone, and choose Send Files.

Windows 11’s Start-menu iPhone transfer requires Phone Link version 1.25032.82.0, a Microsoft account, and a Bluetooth Low Energy connection. The feature is also being gradually rolled out, so it might not yet appear on every PC.^3^

If Send Files works from Start but File Explorer → Send to Phone still produces the storage warning, use the Start-menu route and report the Explorer-specific failure through Win+F → Apps → Phone Link.

3. Repair Phone Link if both routes fail

Repair preserves the app’s data:

1. Open Start → Settings → Apps → Installed apps.
2. Find Phone Link.
3. Select … → Advanced options → Repair.
4. Reopen Phone Link and test again.

If Repair does not fix it, return to the same page and select Reset. Reset removes the app’s local configuration, so the iPhone will need to be paired again.^4^

4. Rebuild the iPhone-side OneDrive connection

Use this only if OneDrive on the iPhone is signed into the correct account but does not synchronize normally:

1. Remove OneDrive from the iPhone.
2. Reinstall it from the App Store.
3. Sign in with the same personal Microsoft account used by Phone Link.
4. Open OneDrive and allow synchronization to complete before retrying.

Microsoft lists reinstalling OneDrive as the recovery step when its iOS app is not syncing, launching, or operating correctly.^2^ A closely matching Phone Link/iPhone case also recommends re-pairing the iPhone and reinstalling OneDrive after storage has been ruled out.^5^

If the error remains after confirming the account, updating, and resetting, include the Phone Link version, file type and size, and a screenshot of the complete alert in the Feedback Hub report.
