Authentication failed error on Outlook application on Android device

Question

I am experiencing this same issue of the Outlook application on my Samsung Galaxy (Model SGH-T959V, Firmware Version 2.2.1).  I first encountered the issue when I updated my Hotmail application a couple of weeks ago.  That Hotmail update then provides no other option than to Upgrade to Outlook.  After installing the Outlook application, I sign in using my hotmail email and password.  The next step asks if I will "let this app access your info" at which point I press the Yes button.  Soon after that, I receive a message that "Authentification failed; Authentication was not successful" with a button to "Try Again."  I have tried again multiple times.  I have also tried uninstalling and reinstalling the Outlook application numerous times for the past two weeks and I run into the same result.

Please fix this issue soon or reinstate the previous version of Hotmail in the Play Store since the Hotmail application was working just fine.

I appreciate your time.

Peace be with you.

Hi StephanieHe @ Sam 1000,

Welcome to Microsoft Community. We apologize for the delayed response.

I can see that you are also receiving the same authentication error when using the Outlook.com app. Let me assist you with this.

In order for us to determine the root cause of this issue, we need to gather some information and clarification. Kindly answer all the questions asked by my colleague Levi on the above post. I have created a private message area for the both of you where you can provide the needed information. You may refer to the private message tab  or you need to click the notification that states “You have a private reply to this message. Click here to read it on our secure private messages section.", be sure that you are signed in to view my message.

We will be waiting for your response.

Hi theepilady,

Thanks for providing the information we need. Before we forward this concern to our support specialist, can you please verify if Two-step verification is enabled on your account? To check, please refer to the steps below:

1. Sign in to your Microsoft account by going to http://account.live.com.
2. On the left side panel, click on Security info.
3. Click on “Turn off two-step verification” under Two-step verification.

If you've enabled Two-Step Verification, you will need an app password to access your account when using mail apps. For more information, you can refer to this article:

App passwords and two-step verification

Let us know how things turn out.

Thanks,
