What Can I Do if Windows 10 Calendar Is Not Working?

If you use Windows 10, you might use the built-in Calendar app to plan your day and stay on top of your schedule. Unfortunately, sometimes the app can have issues, like not opening, crashing, or showing the wrong information.

It’s frustrating when this happens, but don’t worry – there are things you can do to fix the problem and get your Calendar app working again. In this article, we’ll go through some helpful steps to troubleshoot the issue and get your Windows 10 Calendar back up and running smoothly.

Restart Your Computer

Different programs run simultaneously when we use our computers, requiring various resources like memory, storage, and processing power. Sometimes, a program might stop working due to conflicts with other running programs or resource limitations. Restarting the computer can free up these resources, shut down all processes and programs, and start the system fresh. This can help fix errors that were causing the program to fail.

This can also reset any temporary data or settings causing issues. For instance, restarting the computer can fix calendar app issues like not opening, adding or viewing events, or syncing with other devices. However, if the problem persists, additional troubleshooting steps may be needed, like updating or reinstalling the app or checking for software updates.
