    If your Outlook Calendar is not saving changes to appointments or new events, this issue could be caused by several factors. Here are some troubleshooting steps you can take:

    1. Check for Updates: Ensure that your Outlook is updated to the latest version, as outdated software can lead to performance issues.
    2. Repair Office Programs: You can try repairing your Office installation. To do this, exit any running Office programs, open Control Panel, go to Programs and Features, right-click on your Microsoft Office installation, and select Repair.
    3. Use the Inbox Repair Tool: If your Outlook data files are corrupted, you can use the Inbox Repair Tool (scanpst.exe) to fix them. This tool is included with your Outlook installation.
    4. Antivirus Software Conflicts: Sometimes, antivirus software can interfere with Outlook's functionality. Ensure your antivirus software is up-to-date, and consider disabling any Outlook integration within it to see if that resolves the issue.
    5. Create a New User Profile: If the problem persists, creating a new Outlook profile may help. You can do this through Control Panel by selecting Mail, then Show Profiles, and adding a new profile.
    6. Selective Startup: If other applications are conflicting with Outlook, performing a selective startup can help identify the issue. This involves disabling non-Microsoft services and startup items to see if the problem continues.

    If none of these steps resolve the issue, you may want to consult further resources or support for more specific guidance.
