OneNote Android app sign-in failure with Error Tag 9hehw and Code 0 (Entra ID authentication token rejection), Recent Pages not displaying

Andre Fortier 140

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.

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.

I have been experiencing the same Issue 1 for the past several days on Android. I can access one note ok from Windows and have cleared cache and many of the same fix attempts to no avail. I still can use android onenote but my changes do not merge onto the windows OneNote.

I get the same login error 9hehw on Samsung Galaxy S22+, but it only affects sticky notes, not OneNote. I get to both apps accessed with the same Android App Icon. I just switch from one to the other by tapping on the contact icon in the upper left corner. OneNote syncs fine. Sticky Notes says I'm working off-line.

I'm having the same issue regarding OneNote for Android unable to sign in/sync – Error 9hehw.

I also can access OneNote on my laptop and via the web. I tried signing out and signing back in on my phone and it didn't help.

Using Google Pixel 7a

I'm having the same problem synching OneNote on my android phone (Samsung) with Sticky Notes on my PC. It is really frustrating. Same Error message.

J'ai le même problème sur un Huawei 30. L'onglet Sticky note demande de se reconnecter mais il y a alors un message d'erreur (9hehw). Je n'ai plus accès aux sticky notes sur mon téléphone. Cela fonctionne sur windows.

My company Microsoft 365 account works perfectly on the same phone, including Sticky Notes

But with my both personal accounts, OneNote Notebooks work normally but Sticky Notes fail with Access denied for the resource, Tag 9hehw, Code 0. This therefore appears to affect personal Microsoft accounts rather than a specific personal account or device.

I am using a Google Pixel 7 and have just started getting the sync/sign-in message "Tag: 9hehw"

Works fine on Win11 PC

Works fine on iPad

Odd things:

Even though it showed the error, text I added on OneNote app on Pixel did share to desktop OneNote

If I use the "Notebook List" and click on each note book it does seem to restore live data without a sign-in error on my Pixel

So if I don't use "Recent Pages" I can use the app on Android as before

I removed onenote and installed (after clearing storage) and old version

Logged in and recent pages there all good. After some time it will also give the same error.

If I clear storage and install the latest version then I get nothing on the recent pages.

I too am facing the same issue on my android. Keeps showing "Working offline. Sign in to sync your notes." in spite of already being signed in. Pages are not loading. Have tried signing out & signing back in, clearing cache, reinstalling. Even from a different account. Keeps showing the same error: Something went wrong. [9hehw].

A fixed has been applied now. I found I just needed to clear the cache and the data on the app and then log back in on my phone and it was fine. Sticky notes are working again no error.

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.

Thank you very much for the update and for getting this issue resolved.

I initially still had the problem after the fix was rolled out. On my Android devices, I went into the OneNote app settings, opened Storage, and cleared the cache only. After relaunching OneNote, I was able to log in to the Sticky Notes server successfully.

I can also confirm that the Recent Pages list is now displaying and updating properly.

Everything appears to be working correctly on my devices now. I appreciate you and the team investigating the issue and providing an update to the community.

It is fixed for me. I did have to clear the Android app's cache, but once I relaunched OneNote, all is working!

Clear the cache and the data stored in the app and then when you load it if it doesn't automatically connect click sign in but it should be working now you may need to restart your phone

Mine just started fully working again yesterday without having to do anything. Assume an Android update auto-installed.

here is the ACTUAL solution, I had a full OneDrive (5gb/5gb used) so OneNote could no longer sync and produced this weird error 9hehw, the solution was to download all files and folders from OneDrive, as zip files (it creates these automatically), then delete all files and folders from OneDrive itself, then upload the contents of the "Documents" folder from inside the downloaded zip, which included my OneNote files, this restored the use of OneNote and preserved all of my years of notes, sticky notes and notebooks, including converted Samsung Notes files.

You can then upload any files you want to put back into OneDrive, as required, in addition to your OneNote files. Remember to open the newly created "Documents" folder in your now empty OneDrive, and upload all folders found in the downloaded version of this folder, as when you empty out OneDrive, it will recreate the "Documents" folder with nothing in it.

Once you have done this, open the Android app (OneNote) and your notes, sticky notes, notebooks and for example, converted Samsung Notes files, are now back into the app were they were originally. All preserved perfectly.

Same problem for me on a Samsung Galaxy S23 that only started happening in the last day or two.

I have the issue with the OneNote Sticky Notes sign-in and error code, but I see something mentioning a permissions issue:
```
**Correlation Id:** cdc1adb5-971e-ee4a-923d-695862b68927

**Timestamp:** 2026-08-31T09:03:04.000Z

**DPTI:** 2b9e14c1c1fa7bbe

**Message:** Access denied for the resource.

**Tag:** 9hehw

**Code:** 0
```
I've tried clearing the app cache, restarting the phone, signing in and out etc, but nothing fixed that.

In my case I have NOT (yet) noticed any page merge issues as all my pages are still syncing correctly between Android and Windows desktop. It is just the recent pages that stopped updating and kept giving the Sticky Notes warning and subsequent sign-in error.

Also the same issue with Pixel 8 pro. Have tried all of the suggested ways to fix the problem (logout in all 365 apps, empty cache). Nothing has changed. So please Microsoft, it's in your side. Fix it or i will switch to Google or another app with cloud synchronisation that works.

Same issue and message as above from Pixel 10 Pro. My old Pixel 6 works does the same thing. I have been able to work around it by selecting the Notebook List tab instead of the Recent Pages. Under Recent pages, it gives a message: "Working offline. Sign in to synch notes". And when I try, it gives me the same error. But if I switch to the Notebook List tab, it accesses the notebooks and pages, and synchs with my PC.
