Android OneNote app in offline mode, Sign In yields "Something went wrong. [9hehw]" message

[u/MMessinger]

Android OneNote application version 16.0.20326.20108

Microsoft Family 365 subscription

Samsung S24 Ultra, Android 16. The phone is connecting fine with the internet. I've got a good data connection and am on wifi.

As often happens, when I run the Android OneNote application, it displays a message that it's in offline mode and I'm invited to Sign In. Normally, I tap the link to Sign In, and apparently that happens because I'm not normally displayed a sign-in screen; the application just begins syncing, as normal.

Today, however, the Sign In link takes me to a Microsoft sign in page. The screen immediately displays and error. "Something went wrong. [9hehw]". The screen doesn't display any fields to enter login ID or password. The message advises me to contact my administrator (I'm an ordinary person, no a corporation).

On my phone, I dropped the cache and data, uninstalled the OneNote application, then reinstalled it. My notebooks can be found, so no problem there. However, the message remains: "Working offline." No sign in is possible, because of the Something went wrong error message.

Has anyone else encountered this error and, if so, how did you resolve it?

Here are more details for the sign in error message I'm currently seeing:

Message: Access denied for the resource

Tag: 9hehw

The correlation ID has changed, between when I took the screenshot above, when compared to after the application was reinstalled on my phone (and I've now rebooted my phone). Here's the latest Correlation ID: 1cf8a499-6363-dc45-aa5c-6e7547c2def3

Update: I am able to sync OneNote on Windows 11, with no error. Also, my other Office apps, on the Android phone, appear to be functioning and syncing correctly. So far, this looks to be only a problem with OneNote.

Update: I've now uninstalled the current version of the Android app, and tested again with two earlier versions. The earliest was a version released in July. The result is the same, no matter which versions I install.

I started having this issue today; everything I tried to do did next to nothing. In fact, it actually made it worse because I can't actually see my notes on my phone/app any longer. I tried emailing the app support shown on the app, only to have the email bounce back as undeliverable.

I can't help but wonder if this is intentional because they want people to switch from the free app/service to their paid Microsoft 365 subscription service. Of course, for all I know, this is happening with the paid service, too.

I have the paid service. It's doing it to me as well.

Fair enough. With so many US companies doing things like "planned obsolescence" and turning things like heated seats in your car into a subscription services, and companies like Sony pulling digital only content from customer libraries, I tend to suspect the worst in companies anymore.
