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 1

hello

Ive read all previous posts and havent seen the exact issue i am having. I get the authentication failes message although I am able to access my email acct. The problem is I get the notification twenty for seven every 15 or so minutes. what can I do to make it stop? Or do I need to just use the gmail acct that came with my phone and dump my msn acct   .... which I have had for several years.  I just dont want to hear that notification buzzer go off when I can't determine what is causing it.

thank you

Answer 2

Was there ever a resolution to this issue?  I recently had to re-download the outlook.com app and set up my hotmail accounts.  It keeps telling me Authentication Failed Try Again.

I've uninstalled and re-installed this app 2 more times and the same issue.

No resolution yet, sad to say, I did get a case number and the assurance that there would be a responce in 24 hours... but that was 4days ago. At this stage of the game I don't know if microsoft.com is even microsoft or msn or if I'm communicating with somebody on the other side of the planet.

Answer 4

Just to help others (NO thanks to the Microsoft team [as usual]) :

I had the problem and solved it by shutting off the 2-step verification process under the outlook account settings.

once it was off - everything synced back to normal, no hassles, no problems verifying passwords or settings.

Answer 5

Just wanted to advise (assuming its the same problem others are having)....

If you have two factor enabled, the mail apps wont work with your hotmail password. You gotta go get an app specific password for each mail app you use.
