I have also been having issues with outlook, Teams, and other apps on my Samsung S25. I have already tried uninstalling and reinstalling the apps but things are not working. Something is wrong.

I first noticed a problem with Microsoft Authenticator and then started noticing it on Outlook mobile and other apps. I have several problems with that standard, routine suggestion of "just uninstall and reinstall" because this is not just a time suck, it presents a potential security issue. Right now, sites that need MFA via MA to get in give an "I can't use MA right now" link on the pop-up that says "open MA and enter the code shown." Doh!

It'd be funny if it weren't so maddening...

I was having the same issue as above. First noticed it on 4/18ish. Uninstalled Outlook app, reinstalled on 4/19, issue remained. I found this thread today and it works.

I have been having the same issue. It's so frustrating. I've uninstalled and reinstalled multiple times and still the same issue

Hi @Gutierrez Joel (US Stores) and everyone,

I found a method that might help you with this issue:

Please follow the exact steps below:

Settings -> Apps -> Search for "Android System WebView" -> App Details In Store -> Remove Updates
Reboot
Settings -> Apps --> Search for "Android System WebView" -> App Details In Store -> Update
- Note: If "Android System WebView" doesn't appear in the app list, go to: Settings -> Google -> All services -> System Services -> Select "Android System WebView"
Reboot
Launch Teams/Outlook & log in.

Please try and let me know if this solution works for you all.

I look forward for your feedback.

This issue was happening to me and started last week 2026-04-16 or slightly before. First attempt was to nuke all Microsoft off my device: That worked for 2 days. I've just followed the above and that seems to have worked for now at least, without nuking outlook etc. (which is good as getting proper email signatures setup is a hassle).

I have Samsung galaxy s25 plus. I did the search but I didn't see the option for app details in store. I'm going to try the other option that you provided. Thank you

I'm having the same issue. Also on a Samsung S25 which seems to be the same for other users on this thread. I tried this workaround, and whilst it worked at first it only lasted half a day. I think it was more to do with restarting the phone than the workaround because I've found if I restart my phone it works for a while before freezing again.

The reason people cant find it is because you need to go to Apps in settings. @Jayden-P please correct this post. You left out a step, Settings -> Apps -> Search for "Android System Webview" -> App Details In Store -> Remove Updates

Reboot

After the Reboot, for me at least, outlook started working. I, so far have noticed zero affects from unintalling updates other than my outlook started working again. But im assuming not having the updates could potentially cause a security risk, Though at the moment I dont know how.

This fixed my Outlook and MS Authenticator issues on my S22U. It's been working for about 6 days now. I didn't want to say anything earlier for fear of it only working temporarily (the reboots alone were only good for a couple of hours). This worked! Many thanks!

Answer 2

Hi @Gutierrez Joel (US Stores)

Thanks for reporting this issue and I sincerely apologize for the inconvenience this may have caused to your workflow.

I have seen a several users who are in the same situation as yours. However, I have not found any official documents addressing this unexpected issue.

Can you please provide your Android version as well as your Office apps versions?

In the meantime, please use Outlook in the browser on your mobile as an alternative. For Excel, Word and PowerPoint, you need to use the web version on your computer

I know this is not a definite solution but as for now, to reduce the interruption, please use the method.

Lastly, please report the issue via Outlook · Community. (Remember to include your app versions as well)

After you finish submitting, please drop the link here so I and other people can upvote it for you. The more people upvote, the faster Microsoft will be aware of this issue.

I really apologize for this situation. Thanks for your understanding and patience.

Note: Please follow the steps in our documentation to enable e-mail notifications if you want to receive the related email notification for this thread.

Microsoft Authenticator app updated today from the Google Play Store and the update appears to have fixed the issue on my device (S25Ultra). I am now able to open/use Authenticator, Outlook, Excel, Teams, Word, etc. that were not working for the past week.

I'm having this issue the only work around that I have been able to find that works for me has been to move all of these to a secure folder and then they suddenly work

There are certainly other inconveniences to having all of these in a secure folder.

I couldn't find the webview the other instructions talked about so hopefully this helps someone. Obviously a larger issue that has started over the weekend

Hi @Scrubgrub

Thanks for your sharing. I'm sure your information will be helpful to other as well.

Answer 5

Try the following steps on the Android device to get the Microsoft 365 apps (Outlook, Word, Excel, PowerPoint) working again:

Confirm Android and app support
- Make sure the device is running one of the latest four versions of Android, as Outlook and other Microsoft 365 mobile apps are optimized for these versions.
- If possible, update Android to the latest available version, then restart the device and try the apps again.
Fully reinstall Outlook and other Office apps Since clearing cache and a basic reinstall did not help, perform a more thorough reset:
1. Uninstall Outlook, Word, Excel, and PowerPoint from the device.
2. Restart the Android phone.
3. Reinstall the apps from the Google Play Store.
4. Open Outlook first, sign in, and allow it to complete any initial “optimizing” or sync steps without interrupting the app.
5. Then open Word/Excel/PowerPoint and sign in with the same Microsoft 365 account.
Check for mobile setup or install issues
- Follow the guidance for setting up Office apps and email on Android to ensure the account is added correctly and the apps are fully configured.
- If email or documents still do not load, use the mobile troubleshooting guidance for additional checks (network connectivity, sign-in issues, etc.).
If the problem persists
- If using a work or school account, contact the Microsoft 365 admin to verify there are no device or account restrictions.
- If still stuck after the above steps, use the self-help troubleshooting for Outlook mobile issues or contact Microsoft 365 support from the admin portal if this is a business tenant.
