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.

Answer 4

I've changed the phone now, but from memory there was a new Hotmail app available in the store.  I downloaded this and had no further issues, so looks like MS fixed the issue (for me anyway).

hth,
