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.
Check the application header or taskbar icon to confirm if you are using the default Windows Calendar app or Microsoft Outlook.
If using Windows Calendar, open Windows Settings, navigate to Update & Security, and check for pending updates that might patch the app.
If using Outlook, go to File > Office Account > Update Options, and click 'Update Now' to ensure you have the latest stable version installed.
Repair or Reset the Calendar App
If the application keeps crashing or discarding edits, repairing the software can fix corrupted files causing the issue.

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.
