Calendar is one of the default Windows 10 apps. These universal apps generally work fine, but some users have found that they don’t always open and launch (now known as emerging issue 70008) or crash just after opening. So if Calendar isn’t working as it should, here are some ways you can fix that app.

Here are some more similar problems you can fix using the solutions presented below:

  • Windows 10 Calendar app won’t open
  • Windows 10 Calendar app crashing
  • Windows 10 Calendar app not responding

Fix: Calendar app doesn’t work in Windows 10

Solution 1 – Check if  Windows Update is Enabled

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 follows.

  1. Press the Cortana button on taskbar, and enter ‘services’ in the search box.
  2. Select Services to open the window shown directly below.
  3. Then you should double-click Windows Update to open its Properties window.
  4. 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.
  5. Then you should press the Apply button and click OK to confirm the settings.

Solution 2 – Check for Calendar app Updates

Have you switched off the automatic app updates? If so, now might a good time to check for new Calendar updates as follows.

  • Click the Start menu button and then select the Store tile to open that app.
  • Now click 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 Check for 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.

Solution 3 – Run the app Troubleshooter in Windows

Windows has various troubleshooters for you to fix things with. One of those is the Windows Store Apps troubleshooter that can fix Calendar and other apps. This is how you can fix Calendar with that troubleshooter:

  1. Go to the Settings app.
  2. Head over to Update & Security Troubleshoot.
  3. Select Windows Store Apps, and go to Run the troubleshooter. 
  4. Wait for the process to finish, and follow further on-screen instructions along the way.
  5. Restart your computer.

Solution 4 – Clear the Windows Store Cache

The Windows 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 hotkey.
  • 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.

Solution 5 – Reset the Calendar app

Windows 10 now includes handy Reset options for apps. The Reset option effectively restores Calendar to its default settings. This is how you can reset Calendar in Windows 10:

  1. Go to the Settings app.
  2. Head over to Apps Apps & Features. 
  3. Select Mail and Calendar, and go to Advanced options. 
  4. Scroll down and click Reset. 
  5. 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.

Solution 6 – Re-install the Calendar App

Another good way to fix Calendar is to re-install it. Even though it’s a native Windows 10 app, and can’t be uninstalled the same way as third-party apps, you can still re-install Calendar to fix it. This is how you can re-install Calendar in Windows 10:

  1. Go to Search, type powershell, and open PowerShell as Administrator.
  2. Type in the following line, and press Enter: Get-AppxPackage Microsoft.windowscommunicationsapps | Remove-AppxPackage

    3. Click “Repair All” to fix all issues with Patended Technologies (requires upgrade).

  4. 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:

  1. Go to Search, type powershell, and open PowerShell as Administrator.
  2. Type in the following line, and press Enter: dism /online /Add-Capability /CapabilityName:OneCoreUAP.OneSync~~~~0.0.1.0
  3. Wait for the process to finish and restart your computer.

Solution 7 – Run the SFC scan

The next troubleshooting tool we’re going to try is the SFC scan. This is Windows’ own built-in troubleshooter designed to deal with various kinds of problems. Including the app problems. Here’s how to run the SFC scan in Windows 10:

  1. Go to Search, type cmd, and open Command Prompt as Administrator.
  2. Type in the following line, and press Enter: sfc/scannow
  3. Wait for the process to finish and restart your computer.

Solution 8 – Update Windows

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. To check for updates, simply go to Settings > Update & Security, and check for updates.

Solution 9 – Uninstall updates

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. Here’s how to do that:

  1. Go to Settings > Updates & Security > Windows Update
  2. Go to Update history > Uninstall updates
  3. Now, find the latest update installed on your computer (you can sort updates by date), right-click it, and go to Uninstall
  4. Restart your computer

Now, hopefully, your Calendar app will be running smoothly once more. The above fixes can also repair many other Windows apps.
