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

Same issue here. I have two identical devices, both Samsung Galaxy S20 FE. Both running the same software versions / updates. Both using the same Outlook App. Both using the same wireless connection. One of the phones I have had for 4 years and it is working perfectly. The second phone is new and will not connect, giving the same [9hehw] error over and over. I have a Mac Book and I'm using MAIL with the same account and it works. I have verified the passwords and credentials are the same across all devices. I have tried this with two-step verification enabled, as well as with it turned off. I have also tried setting up the email in the Android Mail app instead of Outlook. It has the same issue as the Outlook App. "Checking incoming server settings..." and then fails with "Couldn't Verify Account."

So Microsoft, if you're actually paying attention to anyone with this issue, let me repeat:

• This is NOT an internet connection issue.
• This is NOT a credential issue.
• This is NOT an app issue
• This is NOT Android issue.
• This is NOT an issue with out of date software
• Using two-factor authentication doesn't matter

This *is* an issue with your system somewhere. Stop offering useless canned responses and escalate this.

This happened to my wife's Samsung phone around July 5, 2024. Authentication error for one email, then it spread to her other emails. It is related to a new Samsung update and conflict with an outdated Outlook Mobile app. Note, there is no updated version of the Outlook Mobile app. There is also no update by Samsung to fix this. MS support is of no help. Their best advise is to uninstall Outlook and then re-install, but if you do this you lose everything and still will not be able to sign in.

I could not find any work arounds.

Here is the only solution that worked: uninstall the Outlook app and use the native Samsung Mail app that comes with your phone.

I am telling you this today, because it just recently happened to my Samsung phone.

Still no updates for Outlook and no updates from Samsung.

Cannot seem to find any answers.

Oh well, I guess it is time to dump my mobile Outlook app.

I am having the same problem and it also started on July 5, 2024. Have tired uninstalling and reinstalling Outlook app. I have a Microsoft Exchange email account and can't get it working on my Samsung G21. I can still get emails in Outlook on my Samsung Galaxy tablet, my laptop, and my desktop. Just not working on my phone.

All credentials and network strength are fine.

I am having the same problem.

After some problems with the Outlook android app, I cleared data, uninstalled and reinstalled, pretty much everything I could think of, now when trying to add my existing email account to the app, I get a log in error, despite using exactly the same login credentials which I have on the desktop a version of Outlook which works fine.

I am out of ideas.

I am having the same issue as above same error screen. Can anyone help.
