Outlook Android App error occurred during authentication. Please try again later.

I am also having the same issue.
It appears that Microsoft and/or Outlook is confused with who is who or what is what, on the logins and passwords.

I have had my own domain name for over 25 years. My email is thru that domain name. It is NOT a business account. This all got messy about 3-4 years ago when GoDaddy and Microsoft merged the email systems.
It seems the login windows/prompts vary, woording ain't real clear, if it wants my Email password or my Microsoft acct password.

I 'factory reset' my Samsung tablet. I went to add my email in the Outlook app. After putting in the email, it asks if Business/Work or Personal account. To me, it is Personal as it is my own personal email via in past, my own domain name.
...have tried both Business and Personal and after trying, both fail to authenticate.

At some point, some click I did on options, it did seem to have me login to my MS account and now when I go to add an account, it finds my email on the MS side and wants to add it. But still fails to authenticate.

I have also cleared the App cache and deleted the app data, with no effect, except to have to relogin to the MS account at some step.

I have logged in on my desktop browser to the Outlook.Office.Com site ok, logged out and back in, so my password works.

Anyone else feel like the process is screwed up and overlapping?
Sure seems like a lot of efforts here for a very basic, simple, email setup login failing.

I have a software company for the past 40 years. If we have treated our customers in this way we would not be in business. I have many friends that have Apple and are shocked as to these issues, with Outlook on Android, with little urgency!

March 2025 And I was having the same issue.

I could log in to my Outlook .com webmail (via Godaddy) so I knew all the settings were correct.

After an hour of losing the will to live I finally thought that I would just have to use the website via google chrome.

STAY WITH ME! This solved the problem.

I signed in to outlook.com via Google Chrome and then hit the 3 dots in the top right corner to add the webpage to the home screen to make it easier to access in the future.

AS IF BY MAGIC IT OFFERED ME 2 OPTIONS:

1. INSTALL APP
2. PIN TO HOME SCREEN

I selected install app and it downloaded the outlook app (that was already on the tablet and phone) so I clicked it and it opened instantly with all my emails already populated. FANTASTIC!

I then had 2 outlook app icons, one worked perfectly and the second said set up an email account (where this headache all started).

I held down the icon of the none functional one and clicked uninstall (expecting it 2 uninstall both Outlook apps, sods law), it uninstalled and the functional one was still there. I hope that this helps someone.

UPDATE: Teams did exactly the same error. I went in to Settings/ Apps / Teams / Storage, I cleared Cache and Data and then in my case I had to sign in to teams using my personal account and NOT the "Work or School" option.

MS Outlook needs to get this fixed, does this error have to do with two part authentication

Really, turn it off and back on?
