OneNote for Android – Sign-In Failure (Error Tag 9hehw / Code 0), Missing Recent Pages, and Random Page Merging

Issue Summary

I am experiencing three serious and potentially related issues with the Microsoft OneNote Android app across multiple Samsung Android devices:

OneNote reports "Working offline. Sign in to sync," but attempting to sign in results in an "Access denied for the resource" authentication error.

The Recent Pages tab does not display any recent pages.

OneNote pages are randomly merging with other pages. This occurs across both older and newly created notebooks and has been occurring daily.

These problems started several weeks ago and affect multiple Android devices. OneNote continues to work normally on my Windows PC and through a web browser.

Because the same problems occur across multiple Android devices while desktop and web access remain functional, this does not appear to be an isolated device configuration or notebook issue.

Issue 1 – Android OneNote Sign-In / Sync Failure

On the OneNote Android app, the Recent Pages screen displays:

"Working offline. Sign in to sync."

When I select Sign in, authentication fails and OneNote reports:

"Access denied for the resource."

The application does not successfully authenticate or restore synchronization.

Error Details

Message: Access denied for the resource.

Error Tag: 9hehw

Code: 0

Correlation ID: 24ec32dd-ab6c-8d48-a65b-6c382b23ab05

Timestamp: 2026-08-29T12:02:53.000Z

DPTI: 49d2831405dcd6ad

The sign-in attempt effectively results in an authentication loop and prevents the Android OneNote client from properly reconnecting to the account.

Issue 2 – Recent Pages Are Missing

On the Android OneNote app, the Recent Pages tab does not display my recent pages.

This appears to be related to the app being stuck in the "Working offline. Sign in to sync" state.

Recent pages and notebook access work normally through OneNote on Windows and through the web.

Issue 3 – Random OneNote Page Merging

I am also experiencing a separate but potentially related problem where OneNote pages are randomly merged with other pages.

Characteristics of this issue:

It occurs across different notebooks.

It affects both older notebooks and newly created notebooks.

It can occur on different pages.

It happens randomly and therefore cannot be consistently reproduced on demand.

It has been occurring approximately daily.

It began during the same general period as the Android synchronization/authentication problems.

Because the behavior is intermittent, I have not been able to identify a specific sequence of actions that reliably reproduces it.

This issue is particularly concerning because it can affect the integrity and organization of notebook content.

Devices Affected

The problem is reproducible across all of my Android mobile devices:

Samsung Galaxy S26 Ultra

One UI 8.5

All available system and application updates installed

Samsung Galaxy Z Flip 8

One UI 9.0

New device set up within the past week

All available system and application updates installed

Exhibits the same OneNote problem despite being a newly configured device

Samsung Galaxy Tab S10 FE

One UI 8.5

All available system and application updates installed

The fact that the same issue occurs on three separate Android devices, including a newly configured Galaxy Z Flip 8, makes a device-specific hardware or local Android configuration problem unlikely.

Access That Continues to Work Normally

The Microsoft account itself remains accessible through other OneNote environments.

I have verified that:

My Microsoft account and Microsoft subscription are active.

OneNote works normally on my Samsung Galaxy Book 6 Ultra Windows PC.

OneNote/OneDrive access through a web browser works normally.

My notebooks remain accessible through desktop and web access.

The authentication/synchronization failure therefore appears to be specific to the Android OneNote client or the authentication/token process used by the Android application.

Troubleshooting Already Performed

I have already performed extensive troubleshooting without resolving the issue:

Verified that the Microsoft account and subscription are active and functioning.

Confirmed successful OneNote access from Windows.

Confirmed successful OneNote/OneDrive access through a web browser.

Cleared OneNote local application data and cache on the Android devices.

Cleared/reinitialized relevant browser/WebView components.

Removed system-level account/link integrations, including Link to Windows, to force fresh authentication rather than reuse an existing broker token.

Retested authentication after clearing the local application state.

Tested OneNote on multiple Android devices.

Tested on a newly configured Galaxy Z Flip 8, which produces the same failure.

Confirmed that all affected Samsung devices have current software updates.

None of these actions resolved the problem.

Why This May Require Escalation

Given that:

the same authentication error occurs across multiple Android devices;

one of the affected devices is newly configured;

Windows OneNote continues to function;

browser-based OneNote/OneDrive access continues to function;

the Microsoft account and subscription are active;

clearing Android application data and forcing fresh authentication did not resolve the problem; and

the Android client specifically reports "Access denied for the resource",

the evidence suggests a problem with the authentication/token exchange used by the OneNote Android client rather than a simple local cache or individual-device problem.

The error details, particularly the Correlation ID and timestamp, may allow Microsoft to trace the failed authentication request in its logs.

I would appreciate having this case escalated to the appropriate OneNote/Microsoft identity engineering team so that the authentication failure can be investigated.

I would also appreciate confirmation as to whether the missing Recent Pages and random page-merging behavior could be consequences of the Android client remaining in an offline or partially synchronized state.

Primary Error for Engineering Investigation

Error: Access denied for the resource Tag: 9hehw Code: 0 Correlation ID: 24ec32dd-ab6c-8d48-a65b-6c382b23ab05 Timestamp: 2026-08-29T12:02:53.000Z DPTI: 49d2831405dcd6ad

Please investigate the corresponding authentication request and advise whether this represents a OneNote Android authentication/token issue or an account-side resource authorization problem.

Hello everyone, I want to apologize for the silence here. We have been hearing the reports and have been performing investigations behind the scenes. We have identified the root cause and are actively rolling out a fix to our backend. Please do not uninstall or reset OneNote. You will simply need to restart the app. The rollout will take some time, so it may take a day before everyone sees the fix.

This does not affect core Notebook sync, but rather supplementary features such as the Recent Pages list. You can still edit and sync your OneNote sections and pages, but the recent list will be outdated until the fix reaches saturation.

I apologize for how long it has taken us to resolve the issue.

    Addendum

    I wanted to share how I ended up here, in case it sounds familiar to anyone else:

    Support Round 1: I spent two hours with an initial Microsoft support agent who ultimately could not resolve my issues. Suddenly, the agent provided a canned "solution" that didn't address any of the three problems I was experiencing, stated that the issue was resolved, and abruptly ended the chat session.

    • Support Round 2: Armed with my case number, I started a new chat with a second agent. After explaining that my previous session was cut short and providing the case number, I was asked to repeat everything from scratch. After another two hours, that agent finally advised me to post my issue here on learn.microsoft.com.

    So, here I am—and it's clear from the comments that many of you are experiencing this exact same thing. However, given that this is a community space, I'm wondering: has anyone here actually had a Microsoft representative or engineer respond to a thread like this? If not, does anyone know how we can get official traction on this?

    Why I Looked Beyond OneNote - Sharing if you're interested

    Since this isn't the first time I've had issues with OneNote, and Microsoft doesn't seem to support fixing it promptly, I explored other options. I didn't want any monthly subscription fees, which limited my choices—tools like Evernote, which I used before and found reliable and excellent, are subscription-based.

    Why Google and Samsung Didn't Fit

    • Google: I evaluated Google's ecosystem, but it didn't fit my workflow. While Google Keep has a great mobile app for Android, Google does not offer a standalone, native desktop application for Windows (relying instead on a web-based/PWA interface). Furthermore, Keep uses a flat system of labels and colour codes rather than traditional hierarchical notebooks, and it lacks the advanced table formatting and rich document layout tools that I depend on heavily.
    • Samsung Notes: I also tested Samsung Notes on mobile and PC. Although it was nice and offered automatic sync without a subscription, it lacked the advanced formatting I depend on, especially for tables and proper hyperlink functionality.

    Discovering Joplin & The Migration Process

    I then discovered an open-source tool called Joplin and installed it a few days ago. After extensive testing, I am now migrating all my OneNote notebooks, sections, and notes over to it. I was able to export my notebooks directly from OneNote and easily import them into Joplin, which made the migration super smooth and painless.

    Joplin's overall structure is built around notebooks (folders), and I can easily replicate OneNote's section functionality by creating nested folders via drag-and-drop. I've found I get all the same core functionality of OneNote while breaking my dependence on Microsoft.

    Final Thoughts & Syncing

    While I liked OneNote and used it for about 2 years, having it broken like it has been lately—along with a lack of proper support or any indication that issues are being addressed actively—left me looking for something more reliable with better support. Even though Joplin is open source and has adequate community support, if you are like me and need something stable, I thought I'd share my path in case it's useful.

    Syncing is seamless; I'm using OneDrive, but it also supports other cloud-based sync options for different devices like Dropbox, or optional paid cloud services for those who need team collaboration.
