Windows 10 mail app not working? Here are the fixes

Besides keeping your emails organized, the default Windows Mail app also sends you notifications so you don’t miss urgent emails. Unfortunately, when the app stops working properly, it also means those notifications stop coming in, which can cause you to lose track of an important event.

If your app won’t sync, can’t receive any emails, or keeps crashing, you can manage your emails using a web browser instead. However, if you want to start using the app again, our guide will help you fix it.

1. Try some common fixes for Windows systems

As always, when troubleshooting a problem on your computer, you should start by restarting your system. Especially if you haven’t turned off your computer for a long time. This way, you give it a chance to close any background apps consuming its RAM resources, clear app cache, and install all available updates to keep it running smoothly.

Also, check if you are running an outdated version of Windows, especially if you have paused updates. Open Settings and head to System > About to check if your system is up to date.

If these two simple solutions do not fix the problem, move on to the next solutions.
