My Microsoft Apps have stopped working on my Samsung Ultra S25

Question

My Microsoft Apps have stopped working on my Samsung Ultra S25

Angela Dow 55

I have Samsung S25 ultra and this week my microsoft apps stopped working. I noticed it first on my outlook emails - they weren't updating and then they disappeared just a black page no messages. My Teams app didn't allow me to make a teams meeting on Wednesday either, it just had the spinning circle trying to connect so had to switch to my laptop. Everything is working fine on my PC and laptop its just my phone that Microsoft has stopped working on. I'm not aware of any updates on my phone this week but I do see that there are a lot of other people having the same issue this week and wondered if you could advise how we fix this please? Many thanks

I was able to get Authenticator, word, excel, ppt and Teams back, but outlook is still fried. I've uninstalled outlook, rebooted, cleared data, cleared cache. If an uninstall and re-install doesn't work, what else can I do?

Outlook wasn't syncing at all, and after resetting the account, none of the emails populated. The solution from Patrick fixed the issue for now.

This worked for 2 minutes with Teams. The only way I have been successful is putting all Microsoft apps into the secure folder it works but is inconvenient. If I need to take a photo or attach a document, I have to add it to the secured folder etc.

My authenticator won't even open a code any more on my phone. My Teams won't sync. My outlook won't sync. Deleting and reinstalling only works for about 2 hours. I tried to uninstall the android update and it worked for about 4 hours then stopped. Im on two phones- Galaxy S24 and Galaxy S24+... both are not working at all with Microsoft as of a few days ago.

I know its a Microsoft problem because ALL OTHER APPS ARE WORKING JUST FINE. Please help

I'm telling you the only real work around right now is putting your authenticator teams and outlook into the secured folder.

It will require you to sign in like a new registration, but it will work.

Go into your settings then apps and find Android System WebView and click the 3 dots and remove updates. Then open Teams or Outlook and it will have you sign back in and it should work. Had the same issue for over a week and that resolved it.

Go to your settings and search Secure Folder. Then set it up and add Outlook Authenticator Teams etc. I'm at about 18hours of the apps working perfectly in the Secure Folder. So far all of the other solutions like un-installing the Samsung update have only given me 4 hours of resolution. I'm thinking the Secure Folder is going to be the fix for now!

Hi, not using teams on my phone or company portal, the only issue I am seeing is phonelink is now not working properly, I cannot load any apps on my laptop without first unlocking my phone, rendering phone link now completely useless to me, is this part of this issue?

Answer 1

Patrick DeLine 115

This issue was due to a WebView regression from the Samsung April 2026 security update.It can be resolved by following these steps:

Settings -> Search for "Android System Webview" -> App Details In Store -> Remove Updates
Reboot
Settings -> 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.

These steps worked for me, although the steps to find Android System Webview were slightly different on my Samsung Galaxy S25 Edge (Android 16). I used Google to figure out how to find it on my phone and followed those steps. After finding the service, I was able to follow your instructions and solve the issue. Thanks!

This worked for me - but I've had to repeat the process daily to keep being able to look at emails (sometimes twice a day) and the authenticator app barely functions. Hoping there will be an update to fix this soon, as it's very frustrating.

I have a samsung galaxy s25 ultra and following Patricks instructions has worked for me since i followed them two weeks ago. I turned off and have not reactivated my microsoft defender which seems to have avoided continual issues as all my microsoft products have continued to work without fault since doing this. It looks like there is some kind of clash issue with samsung and microsoft protection that needs sorting.

Our role is limited to providing technical guidance on reported issues, requests, or ideas.

Hi @Angela Dow

I completely understand how frustrating it is when essential apps suddenly stop working, especially when you rely on them for daily emails and meetings!

From what you have shared, I understand that your Microsoft apps, specifically Outlook and Teams have stopped functioning on your Samsung S25 Ultra this week. Outlook is displaying a blank black screen, and Teams is stuck on a connecting loop, while everything continues to work perfectly fine on your PC and laptop.

Have you had a chance to try the troubleshooting steps mentioned in the previous replies on this thread?

If those did not resolve the issue, could you please provide a few more details to help us investigate further?

-App Versions: What are the exact version numbers of the Outlook and Teams apps currently installed on your device?

-Android Version: Which specific Android version is your phone running right now?

Additionally, a few other users facing this exact same issue this week have reported that simply rebooting the phone has acted as a successful workaround. Please give that a quick try and let me know if it brings your apps back to life!

Looking forward to your update so we can get this sorted out.

even better when Authenticator wont work either.

these steps as above (thanks Patrick) seem to have worked. for now at least.

Settings -> Search for "Android System Webview" -> App Details In Store -> Remove Updates

Reboot

Settings -> 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

Hi @Eckert, Lauren E & @Rebecca Jones

Thank you for your update.

At the moment, the last solution I can suggest is to use Secure Folder on your Samsung tablet:

Go to Secure Folder > Add apps, and then try adding your application there.

Please note that I have tested Teams, Outlook, and Authenticator in Secure Folder, and they worked fine. You may also try this with your Word app.

In my case, the Word app is still functioning normally, so I am not able to reproduce the issue at this time.

Additionally, if you are using Microsoft Authenticator, please make sure the app is updated to the latest version from the Play Store.

Ref: MS Authenticator app not working after Android update - Microsoft Q&A

Please try and get back to me.

Answer 4

For this scenario where Outlook and Teams have stopped working only on a Samsung Android phone while everything works on PC and laptop, the supported steps are:

Uninstall the affected Microsoft apps (Outlook and Teams) from the Samsung S25 Ultra.
Restart the phone.
Reinstall Outlook and Teams from the Google Play Store or Samsung Galaxy Store.
Open each app and sign in again with the Microsoft 365 account.

This approach matches the recommended resolution for similar mobile sign-in or app issues where an "unexpected error" occurs on Samsung devices.

If the issue persists after reinstalling, contact the organization’s Microsoft 365 admin or technical support, as advised for Microsoft 365 work or school accounts, or contact Microsoft support for Outlook.com-type accounts.

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.
