OneNote Mobile for iPhone - RE: "Login failed, error: 400" Error

  • Comments 63

First of all thank you very much for your interest in OneNote Mobile for the iPhone, there has been a tremendous response thus far.

We have received reports from customers who are hitting an error on initial login, with the following message: "Login failed, error: 400".

The team has been investigating the issue and believe we have identified the cause. We are working on an update. However the underlying cause is an intermittent issue, due to overwhelming interest in the app. The workaround is to keep trying to sign in, once you get past this error then OneNote will sync without any problem.

Thank you for your patience and interest in OneNote, we all apologize for the inconvenience.

    Why no other markets? Even Canada falls under the standard office license. I can see small developers doing this, but te product you tie into works here so why notake te app available? It's only a region checkbox, nothing huge an logistical..

    Back to evernote I go...

  • There's nothing more frustrating than downloading an app and then having it not work right off the bat.  I've been trying over and over to get this to work and I keep getting error 400 and 500.  If I'm getting error 500, I wonder what the other 499 errors are for.

    If I can't get it to work shortly, I'm going to delete the app and forget I ever had it.

  • Had to try to login about 25 times, then it fails to sync notebooks.  How can you not make sure the product works before launching.  Typical Microsoft.

  • Epic Fail, Microsoft. Did it occur to anyone to test this product before releasing it?

  • I clicked "Sign In" three times in rapid succession and it let me in on the third.

    Good luck!

  • Keep trying?  You guys are smarter than that.  Or maybe not.  Life is too short.  Fix it.  It NEVER should have been released.  You all should be MORTIFIED at this abysmal failure

  • After 2 years of waiting I'm so excited that OneNote has been released on the iPhone... but I've since moved on to Android. Any updates on an Android version of OneNote?

    (I'm sure you've all seen the numbers on Android vs iPhone users: mashable.com/.../iphone-android-nielsen)

  • I finally managed to sneak into the login line for OneNote.  Although I didn't realize it when it happened.  I had been tapping the sign in button on the app and waiting for the error message to pop up, tap the cancel button, tap the sign in button, etc. etc. for over an hour.  I would periodically look at my phone, see that it had errored out and try again.

    I guess that I finally did get through to the log in server but I didn't get any type of notification one way or the other.  The screen just sat there looking like it was waiting for a response from MS that I had signed in or errored out again so I just ignored it.  I had to go somewhere so I closed the app and went about my business.

    An hour later I tried it again and was surprised to see that I had apparently been let into the system because the app was working.  So far it seems to be working fine.  I guess that MS simply way underestimated the number of people that would want a free app and didn't have the resources it needed to get people logged in on release day.  Not a great first impression, but it seems to be working just fine now.

  • It works on iPad, once on iPhone awesome!!!!

    Please please pweez make iPad app.. I will pay formore functionality for a iPad version.

    This is big!!  Especially for college notes. I will call it my onenote pad!!!

  • Why can't I see my onenote 2007 notebooks? Does this only work with onenote 2010?!?

  • Some comments on the OneNote app (besides the obvious -400 and -500 errors):

    1. I have a notebook over 80megs in size on the skydrive, the syncing started over 3G and while there was a button to interrupt the sync i did not know if i should've. This ate up battery life in huge chunks. Basically it would be nice if some kind of time/size estimate was provided PRIOR to initiating sync.

    2. Even after the sync was done, it takes an extremely long time to sync a single page (just text) over 3G. Not sure if it's my connection, the algorithm to validate what needs to be synced or the MSFT servers.
