How to Fix Missing OneDrive Attachments in Yahoo Mail on iPhone
Question details
The user is unable to select files from OneDrive when trying to add an attachment to an email in the Yahoo Mail app.

- Product
- Yahoo Mail and OneDrive
- Device & OS
- iPhone
- Scenario
- Attempting to attach a file from Microsoft OneDrive to an outgoing message within the Yahoo Mail mobile app.
- Observed behavior
- The OneDrive integration disappears from the Yahoo Mail attachment picker entirely, even though the standalone OneDrive app works perfectly on the same device.
Ensure your iPhone has a stable internet connection and that you have the current login credentials for both your Yahoo Mail and Microsoft OneDrive accounts.
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Integration issues between third-party applications can occasionally occur due to expired authentication tokens or outdated software versions.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.
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.
Open the Yahoo Mail app, tap on your profile icon in the top left corner, and navigate to 'Settings'.
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.
Compose a new email, tap the attachment (paperclip) icon, and check if the OneDrive option has successfully reappeared in the list of available sources.

Use a OneDrive Sharing Link (Workaround)
If direct integration fails, you can manually generate a secure link to your OneDrive file and paste it directly into your email body.
Manage and Share Documents Easily with WPS Office
While dealing with integration issues between mail clients and cloud drives, consider switching to WPS Office for a smoother document management experience. WPS Office is a highly compatible, free Microsoft Office alternative that allows you to easily edit, manage, and generate sharing links for your documents directly from your iPhone without relying on complex third-party app integrations.
- 1. Download the app: Search for WPS Office in the App Store and install it for free.
- 2. Open your files: Use WPS Office to easily open, edit, and manage your documents in a unified interface.
- 3. Share effortlessly: Tap the share button on any document to quickly copy a secure link and paste it into Yahoo Mail or any other messaging app.
