Reset the Mail and Calendar App via Windows Settings

Using the Windows Advanced Options to reset the app clears the corrupted local data that is causing the Calendar to crash upon launch.

When the Windows 11 Calendar app crashes silently, it usually points to a conflict within the local cache. Performing an app reset is the most effective way to clear this cache and restore default functionality without touching the core operating system.

1
Open Windows Settings

Press the 'Win + I' keys on your keyboard to open Windows Settings, select 'Apps' from the left sidebar, and click on 'Installed apps'.

2
Locate the App

Scroll through your list of installed applications or use the search bar at the top to find 'Mail and Calendar'.

3
Access Advanced Options

Click the three-dot icon next to the Mail and Calendar app and select 'Advanced options' from the dropdown menu.

4
Reset the App

Scroll down the page to the Reset section and click the 'Reset' button. Confirm your choice when Windows warns you that the app's local data will be deleted.

5
Re-add Accounts

Relaunch the Calendar app. Since the reset clears local accounts, follow the initial setup prompts to sign back into your email and calendar providers.

Frequently Asked Questions

Why does the Windows 11 Calendar app close without an error message?

Silent crashes typically occur because the local app data or cache has become corrupted, or there is a synchronization conflict with your connected email accounts that prevents the interface from loading fully.

Will resetting the Mail and Calendar app delete my scheduled meetings?

No. Resetting the app only removes the locally cached data and account configurations from your PC. Your actual calendar events are securely stored on your email provider's servers (like Outlook or Gmail) and will sync back automatically once you sign in again.

What should I do if resetting the Calendar app does not work?

If resetting doesn't resolve the crash, try reinstalling the application entirely. You can uninstall it from the 'Installed apps' menu in Windows Settings, and then download the latest version of 'Mail and Calendar' directly from the Microsoft Store.
