How to Fix OneDrive Mobile App Tenant Switching Problems

When you use the OneDrive mobile app with multiple work or school accounts, switching between Microsoft 365 tenants can fail. The app may show a blank screen, refuse to load files, or prompt you to sign in repeatedly without success. This problem occurs because the app caches authentication tokens and tenant metadata from the previous session. This article explains the exact causes and provides step-by-step fixes to force a clean tenant switch on both iOS and Android devices.

Why the OneDrive Mobile App Fails to Switch Tenants

The OneDrive mobile app stores authentication tokens from the last successful sign-in. These tokens are linked to a specific Microsoft 365 tenant. When you try to add or switch to a different tenant account, the app may reuse the old tokens instead of requesting new ones. This causes the app to show the wrong tenant’s files or fail to load any content at all.

The app also caches tenant-specific metadata such as site URLs, library names, and sync status. If the cache becomes corrupted or contains stale data from a previous tenant, the app cannot properly render the new tenant’s file structure. This results in blank screens, infinite loading spinners, or repeated sign-in prompts.

On iOS, additional issues arise from Safari’s shared credential storage. The OneDrive app uses the system browser for authentication. If Safari holds old session cookies from a different Microsoft account, the login flow can get confused and fail to complete. On Android, the WebView cache can cause similar problems.

Steps to Force a Clean Tenant Switch on the OneDrive Mobile App

1. Sign out of all accounts in the OneDrive app
   Open the OneDrive app. Tap your profile picture or the Account icon in the top left corner. Scroll down and tap Sign Out. Confirm the sign-out when prompted. This removes all cached tokens for the current session.
2. Clear the app cache on iOS
   On iPhone or iPad, go to Settings > General > iPhone Storage. Scroll down and tap OneDrive. Tap Offload App to remove the app but keep documents and data. Then tap Reinstall App from the same screen. This deletes the app’s cache and temporary files without deleting your local documents.
3. Clear the app cache on Android
   Open Settings > Apps > OneDrive. Tap Storage. Tap Clear Cache. Do not tap Clear Storage unless you want to reset all app data including saved credentials. After clearing the cache, force stop the app from the same menu.
4. Clear browser data on iOS
   Go to Settings > Safari. Tap Clear History and Website Data. Confirm the action. This removes cookies and session data that can interfere with Microsoft login.
5. Clear WebView cache on Android
   Open Settings > Apps > Chrome or Android System WebView. Tap Storage. Tap Clear Cache. This removes cached login pages that may contain stale tenant information.
6. Restart the device
   Power off your phone or tablet completely. Wait 10 seconds. Power it back on. This clears any residual processes that may hold old authentication state.
7. Sign in to the correct tenant account
   Open the OneDrive app. Tap Sign In. Enter the full email address of the account belonging to the target tenant. On the login page that appears, verify that the tenant name shown matches the organization you want to access. If the wrong tenant appears, tap Use another account and re-enter the email. Complete the multi-factor authentication if required.
8. Add additional accounts if needed
   After the first account is connected, tap your profile picture. Tap Add account. Repeat the sign-in process for each additional tenant account. The app should now show separate sections for each account under the profile menu.

If Tenant Switching Still Fails After the Main Fix

The OneDrive app shows a blank screen after switching accounts

A blank screen usually means the app cannot load the tenant’s file list due to a corrupted local database. On iOS, offload the app again and reinstall. On Android, go to Settings > Apps > OneDrive > Storage and tap Clear Storage. This deletes all app data including saved files. After clearing storage, sign in again and let the app fully sync the file list.

The app keeps prompting for sign-in after switching tenants

Repeated sign-in prompts indicate that the authentication token refresh is failing. This often happens when the device clock is out of sync. Go to Settings > General > Date & Time on iOS or Settings > System > Date & Time on Android. Enable Set Automatically. Restart the OneDrive app and sign in again.

OneDrive shows files from the previous tenant after adding a new account

This occurs when the app caches file thumbnails and metadata from the old tenant. Clear the app cache using the steps in the main fix above. On Android, you can also clear the OneDrive app’s data from Settings > Apps > OneDrive > Storage > Clear Data. On iOS, offloading the app is the only way to remove cached thumbnails.

OneDrive Mobile App Account Switching: Comparison of Methods

Item	Sign Out and Sign In	Clear App Cache	Offload App (iOS) / Clear Data (Android)
What it removes	Authentication tokens only	Temporary files and thumbnails	All app data including local files and credentials
Effect on local files	None	None	Deletes offline files that have not synced to the cloud
Effect on sign-in state	Requires reauthentication	Keeps sign-in state intact	Requires reauthentication
Best use case	Switching between tenants normally	Blank screen or stale file list	Persistent switching failures after other methods fail

You can now force a clean tenant switch on your OneDrive mobile app by signing out, clearing the app cache, and restarting your device. If the problem persists, offload or clear all app data and sign in again. For daily use, switch accounts by tapping your profile picture and selecting the correct account instead of signing out completely. This method preserves each tenant’s cached metadata and reduces the chance of switching failures.
