Verify Application Version and Install Updates

Determine whether you are using Windows Calendar or Microsoft Outlook, and ensure the software is fully updated to resolve known stability bugs.

Different calendar applications require different troubleshooting methods. Identifying whether the crash happens in the native Windows Calendar app or Microsoft Outlook is the first essential step.

1
Identify the application

Check the application header or taskbar icon to confirm if you are using the default Windows Calendar app or Microsoft Outlook.

2
Check for Windows updates

If using Windows Calendar, open Windows Settings, navigate to Update & Security, and check for pending updates that might patch the app.

3
Update Outlook

If using Outlook, go to File > Office Account > Update Options, and click 'Update Now' to ensure you have the latest stable version installed.

Information Gathering: If the issue persists, taking a screenshot of the editing interface (while hiding personal data) can help technical support identify specific conflicts.

Frequently Asked Questions

Why did my Outlook calendar event disappear immediately after saving?

This frequently happens if there is a synchronization conflict with the Exchange server, or if a view filter is currently applied to your calendar that hides certain categories of saved events.

How can I recover a discarded calendar edit?

If the application presented an 'Undo' option right after discarding, pressing Ctrl+Z might restore the text. However, if the app crashed entirely, the unsaved changes to the calendar event are typically lost.

Does WPS Office offer calendar templates?

Yes, WPS Office includes a vast library of free spreadsheet and document templates, including monthly, weekly, and daily planners to help you organize your schedule safely.
