How do I fix my calendar on Windows 10?
- Check if Windows Update is enabled
- Check for Calendar app updates
- Run the app Troubleshooter in Windows
- Clear the Microsoft Store Cache
- Reset the Calendar app
- Reinstall the Calendar App
- Run the SFC scan
- Update Windows
- Uninstall updates
1. Check if Windows Update is enabled
- Press the Cortana button on the taskbar, and enter services in the search box.
- Select Services to open the window shown directly below.
- Then you should double-click Windows Update to open its Properties window.
- The Startup type must be configured to either Manual or Automatic. If it isn’t, select one of those options from the Startup type drop-down menu.
- Then you should press the Apply button and click OK to confirm the settings.
Some have reported that Windows apps don’t open when Windows Update is switched off.
As such, that might be why the Calendar app isn’t working. You can check the update service is enabled as shown above.
2. Check for Calendar app updates
- Click the Start menu button and then select the Store tile to open that app.
- Now click the 3 dots next to your account profile image at the top of the Store window.
- Then click the Downloads and Updates option on that menu.
- A window will open that includes a Get updates button.
- Press that button to check for Windows app updates.
- If any updates are found, a total number will appear beside the user profile image along with a list of apps to update.
- Select to install any updates for the Mail and Calendar app.
Have you switched off the automatic app updates? If so, now might a good time to check for new Calendar updates.
3. Run the app Troubleshooter in Windows
- Go to the Settings app.
- Head over to Update & Security > Troubleshoot.
- Select Microsoft (Windows) Store Apps, and go to Run the troubleshooter.
- Wait for the process to finish, and follow further on-screen instructions along the way.
- Restart your computer.
Windows has various troubleshooters to help you fix things. One of those is the Microsoft (Windows) Store Apps troubleshooter that can fix Calendar and other apps.
4. Clear the Microsoft Store Cache
The Microsoft Store has its own cache that includes cached downloads. Clearing this cache can be an effective fix for Windows 10 apps. You can do that as follows.
- First, you should open Run by pressing the Win key + R.
- Now type wsreset.exe into Run and press OK.
A blank Command Prompt window then opens. Now Command Prompt is clearing the cache, and that window automatically closes soon after. The Store window will then open.
5. Reset the Calendar app
- Go to the Settings app.
- Head over to Apps > Apps & Features.
- Select Mail and Calendar, and go to Advanced options.
- Scroll down and click Reset.
- A small window then opens stating: This will permanently delete the app’s data on this device, including your preferences and sign-in details. Press the Reset button and confirm.
Windows 10 now includes handy Reset options for apps. The Reset option effectively restores the Calendar to its default settings. This is how you can reset Calendar in Windows 10.

6. Reinstall the Calendar App
- Go to Search, type powershell, and open PowerShell as Administrator.
- Type in the following line, and press Enter: Get-AppxPackage Microsoft.windowscommunicationsapps | Remove-AppxPackage
- Wait for the process to finish and restart your computer.
Now that you’ve uninstalled the Mail app, it’s time to install it once again. To install the Calendar package again, do the following:
- Go to Search, type powershell, and open PowerShell as Administrator.
- Type in the following line, and press Enter: dism/online/Add-Capability/CapabilityName:OneCoreUAP.OneSync~~~~0.0.1.0
- Wait for the process to finish and restart your computer.
Even though it’s a native Windows 10 app that can’t be uninstalled the same way as third-party apps, you can still reinstall Calendar to fix it.
7. Run the SFC scan
- Go to Search, type cmd, and open Command Prompt as Administrator.
- Type in the following line, and press Enter: sfc/scannow
- Wait for the process to finish and restart your computer.
This is Windows’ own built-in troubleshooter designed to deal with various kinds of problems including the app problems.
8. Update Windows
To check for updates, simply go to Settings > Update & Security, and Check for updates.
Microsoft can sometimes push the updates for Windows features through Windows Update, instead of the Store.
So, if none of the solutions presented above managed to resolve the problem, let’s see if we’ll have any luck installing the latest available update for Windows.
9. Uninstall updates
- Go to Settings > Updates & Security > Windows Update.
- Go to Update history > Uninstall updates.
- Now, find the latest update installed on your computer (you can sort updates by date), right-click it, and go to Uninstall.
- Restart your computer
Contrary to the previous solution, it’s also possible that the latest update you’ve installed actually caused the problem.
So, it makes sense to delete that update and wait for Microsoft to release a new one.
Now, hopefully, your Calendar app will be running smoothly once more. The above fixes can also repair many other Windows apps.
