Email server not responding on Samsung phone or tablet.

Ensure that your phone is connected to either Wi-Fi or mobile data. You can do this by swiping down from the top of your phone's screen to access the Quick settings panel, then long-pressing the Wi-Fi icon to verify your connection. Additionally, you can go to the Settings menu, select "Connections," and tap on "Wi-Fi." To confirm that your internet connection is functional, attempt to load a webpage or perform a quick search.

In the event that your email provider has made changes to their server, it might be necessary to delete and subsequently re-add your account to update the configuration. Prior to doing so, ensure that you have your email account's username and password readily available. It's important to note that passwords are case-sensitive, and an incorrect entry will result in your phone being unable to establish a connection to the email server.

You can clear the app’s cache by navigating to Settings and then tapping Apps. Select the email app, and then tap Storage. Tap Clear cache.

To clear the app's data, navigate to Settings and then tap Apps. Select the email app, and then tap Storage. Tap Clear data, and then tap OK. This will completely wipe the app and reset it to the original settings.

Using Safe mode will help you figure out if the email app is causing issues with your phone. Press and hold the Power key or Side key. On phones without a dedicated Power key, you can swipe down from the top of the screen to open Quick settings, and then tap the Power icon.

Then, touch and hold the Power off icon. Tap Safe mode when it appears. Your phone will restart and “Safe mode” will be displayed in the bottom left corner of the screen. Check if your email app is still causing issues on your phone. You can also remove it if needed. Restart your phone to exit Safe mode.

If you are still encountering issues, contact your email service provider.
