Question

Microsoft Outlook & Authenticator not working on my Android Phone

Eren Gülümser 5

Hello,

I cannot access Outlook & Authenticator applications on my Android phone.

I've tried reinstalling the apps and tried different networks but that didn't help.

You need to uninstall the recent update for "Android System WebView." Here is how to do it:

__Steps to Fix:__

Open your Android phone's Settings.

Go to Apps (or App Management depending on your phone brand).

Scroll down or use the search bar to find Android System WebView. Tap on it.

Tap the three vertical dots in the top right corner.

Select Uninstall updates.

Open Microsoft Authenticator to confirm it works instantly.

Dear Jaineel,

Thank you for your suggestions. Just to say - I have been facing this issue for the past few week now and have tried:

uninstalling-reinstalling Outlook/Onedrive/Authenticator

uninstalling updates from above apps themselves and WebView

creating Secure Folder and moving the apps there

logging out of all my microsoft accounts

All these seem to work for a few minutes but then the problem finds its way back to me. By going through Reddit communities, it seems that it is something many users have been facing forthe past 2 weeks but remains largely unacknowledged by Microsoft.

I have somehow managed to fix this issue, but I am not sure Jaineel's steps are the 100% solution to this. Leaving the steps I've taken to maybe enlight other people on solving this issue :

I use Galaxy S23, first thing I did was restart the phone but it does some kind of "soft restart" which executes very fast. So this didn't fix my issue

I posted this question here and tried Jaineel's solution. Didn't work.

I re-updated Android System WebView, restarted, also didn't work.

Tried to do force restart with volume down and power button pressed for like 10 seconds, and voila ! Now it works

Hope this helps, I guess fiddling around may work out. Also while trying to fix this issue, I've found that this issue may have something to do with your Google Chrome version as Android often uses Chrome for displaying WebView

Yo Microsoft, get your action together man. The solution you have provided isn't working. It wasn't a problem before and it shouldn't be a problem in the future. Work with Google to solve this ..

Answer 1

Follow these steps on the Android phone to troubleshoot Outlook and Microsoft Authenticator together:

Turn off power-saving / optimization for Microsoft apps
- On some Android devices (especially Huawei and similar):
  - Open Phone Manager (or equivalent system manager app).
  - Go to Auto-launch → Secondary launch management.
  - Enable auto-launch/secondary launch for Authenticator and Company Portal (if installed).
- In Android Settings → Battery or Power saving, disable battery optimization for Microsoft Authenticator, Outlook, and Company Portal so they can run in the background.
Ensure Authenticator can run before Outlook
- Open Microsoft Authenticator (and Company Portal if used by work/school) and leave it running.
- Then open Outlook and try to sign in again. Some devices block Outlook from triggering Authenticator unless Authenticator is already active.
Check Google Play Services and push notifications (for Authenticator)
- Make sure Google Play Services and Google Play Store are installed, enabled, and updated.
- In Android Settings → Apps → Microsoft Authenticator:
  - Ensure Notifications are allowed.
- If using a work profile (Android for Work), also ensure PIN/biometric is enabled for that profile and Authenticator.
Verify device security requirements (for Authenticator)
- Ensure the device requires a PIN, fingerprint, or face unlock to unlock the phone.
- Restart the device, unlock it using PIN/biometric, then open Authenticator and try again.
- Make sure hardware encryption is enabled on the device (see Encrypt your Android device if managed by Intune).
- In Authenticator → Settings → Device Registration, confirm the work/school account is registered and joined to the organization, then retry enabling passwordless or MFA.
If Outlook sign-in still fails
- For a Microsoft personal account, use the online sign-in helper to diagnose account issues: Start.
- For a work or school account, if password or MFA is the issue and self-service password reset is enabled, use: Reset password. If not, contact the organization’s IT admin.
If nothing works
- If this is a work/school device, contact the Microsoft 365 admin or technical support in the organization and share the exact error messages from Outlook and Authenticator.
- For personal accounts, contact Microsoft support and specify that Outlook and Microsoft Authenticator both fail on the Android device even after reinstalling and trying different networks.
