Hi @dale payne

To better understand your situation, may I confirm the following details?

1/ Did the issue also occur when using Outlook on the web?

You can open any browser on your device and sign in at https://outlook.office365.com/owa/ to check whether your mailbox is working properly there.

2/ What is the brand of your device?

In the meantime, you may try the steps below to see if this helps.

1/ Clear browser cache, especially if it contains saved Outlook credentials.

2 / Clear the Outlook app cache:

In my test environment, the steps are: Settings > Apps > App Management > Outlook > Storage Usage

Note: The exact path may vary slightly depending on your device, but the general steps should be similar.

3/ Reinstall the Outlook app

If I’ve misunderstood any part of your situation, or if you have further questions or updates, please don’t hesitate to reply.

Thank you for your time, and I look forward to hearing from you soon.

Yesterday my Samsung Galaxy S25 Ultra in the UK suddenly stopped receiving and sending emails on all three of my microsoft email accounts. None of which are available business or work email. I have tried everything single thing that every single person has stated "to try". And I mean everything. I cannot do a complete factory reset, due to the hundreds of personal photos amongst other things. My phone sits next to my Samsung galaxy Tab S8, where my Outlook and all other microsoft apps work fine. Its a microsoft problem and checking online I am amongst a large number having the same problem. Is there a work around please?

Hi @S Garner
Based on my research, there are currently some unexpected behaviors occurring between Outlook mobile and certain Samsung devices. You are not alone in encountering this, and several other users have reported similar observations.

Based on shared experiences from the community, you may try the following troubleshooting steps, which have helped others in similar situations.

Open Settings > search for Android System WebView.

Select App details in Store > Remove updates.

Restart your device.

After the device restarts, go back to Settings > Android System WebView.

Open App details in Store and update the app to the latest version.

If Android System WebView does not appear in the app list, navigate to Settings > Google > All services > System Services > Android System WebView.

Restart the device once more.

After the restart, launch Outlook and attempt to sign in again.

Note: The detailed steps may vary depending on the device, but the overall process remains the same.

I hope this provides helpful insight and supports you in moving forward.
