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

For some reason when my outlook app is not showing new emails, so I searched online and the advice on Microsoft site was to clear the apps cache and storage (which I did)

This has obviously removed all my setting on my phone so when i go into the app again it asked me to log in again, when i click this is automatically detects my outlook email address, I clock on this (it doesn't ask for password BTW - but i did try to just enter my email and password but same error message) but then just come up with an error saying " error occurred during authentication. Please try again later"

I am using the latest version of Outlook for Android app (27 Feb 2024) - 4.2405.2 (42405820).

I am using Android 14.

I started experiencing this issue today, Feb 27, 2024 as soon as I downloaded the Outlook app for Android.

I can log in successfully to this Yahoo Mail account, using Outlook for Windows, web etc. Only Outlook for Android is a problem.

I had issues with Google and Outlook accounts but then somehow they were resolved when suddenly the Outlook was able to sign in, even when there was the same error message displayed.

How can this be fixed, I need access to my emails asap

Thanks

    Thanks for your reply KING142. As much as I wish you could connect, it's a relief to rear that someone else has tried all the steps suggested but still cannot get it to work correctly. This is really a "conundrum" for me because I can use Outlook on my Mac and on my Samsung S24 to work, but I keep getting that error on my Samsung S9 tablet.

    Fixed this in Android by going to the phone's Settings - Passwords, Passkeys & Accounts, and removing the Microsoft email account.

    Then, long press on the Outlook app and went into the app info settings. tap on storage and clear the storage for the app to reset.

    After doing this, when Outlook detected the Microsoft account, it was not listed as an Outlook account any longer and showed as a Microsoft 365 account instead.

    For iOS, I assume the steps would be similar. Remove the account from the phone's settings and accounts list, and then remove and reinstall the Outlook app (Since there is no clear storage option)

    Hope it helps.

    A great response to Microsoft. Today I have tried countless times on my new A56 to get outlook to work on it and nothing. Thank you for your persistence.

    Hi David, Thanks for your explanation about this issue. Sadly for me, I am certainly NOT tech cavy, so just wondering if you might be able to break this down just a bit more. I suppose I am afraid that I may mess up your instructions and the mess up everything along the way. Perhaps if I look long enough someone may have produced a video showing all these steps for the 'lay' people like me ;) Again, thanks for your help.
