Update Apps and Reauthenticate OneDrive

Keeping both applications updated and manually refreshing their linked connection often restores the missing attachment option.

Integration issues between third-party applications can occasionally occur due to expired authentication tokens or outdated software versions. Reinstalling the apps may not clear the cached connection state, which is why a manual reauthentication is necessary.

1
Update both applications

Open the App Store on your iPhone, search for both Yahoo Mail and Microsoft OneDrive, and tap 'Update' to ensure you are running the latest versions.

2
Access Yahoo Mail settings

Open the Yahoo Mail app, tap on your profile icon in the top left corner, and navigate to 'Settings'.

3
Re-link OneDrive

Look for the connected accounts or cloud storage section within the settings. If OneDrive is listed, disconnect it and then reconnect it by following the Microsoft sign-in prompts.

4
Verify in the attachment picker

Compose a new email, tap the attachment (paperclip) icon, and check if the OneDrive option has successfully reappeared in the list of available sources.

Update Apps and Reauthenticate OneDrive
Contact Yahoo Support: If the OneDrive option remains unavailable after updating and reauthenticating, you may need to contact Yahoo Mail Support directly for further assistance regarding this specific integration bug.
