iCloud Calendar Problem

It looks like you're facing an issue with your iCloud Calendar in Outlook for Windows 11. The error message you've encountered indicates a problem with the MAPI (Messaging Application Programming Interface) related to Apple Internet Services. Let’s break down how to troubleshoot this situation effectively:

Possible Solutions:​

• Ensure iCloud and Outlook are Up-to-Date:
• Make sure you have the latest versions of both iCloud and Microsoft Outlook installed. Updates can fix bugs that might be causing the error.
• Repair the iCloud Installation:
• In some cases, repairing the iCloud installation can resolve issues related to syncing and connectivity.
• Go to Control Panel > Programs > Programs and Features.
• Find iCloud in the list, right-click it, and choose Repair. Follow the on-screen instructions.
• Check for Multiple iCloud Accounts:
• If you have multiple iCloud accounts configured, this might interfere with Outlook's ability to sync correctly. Make sure only one account is set up in iCloud and Outlook.
• Reinstall iCloud:
• If repairing doesn't help, consider uninstalling and reinstalling iCloud.
• Uninstall from Control Panel > Programs > Programs and Features.
• Restart your computer and then reinstall iCloud from the official Apple website: https://support.apple.com/en-us/HT204085.
• Reset the MAPI Configuration:
• Resetting the MAPI configuration might help:
• Exit Outlook, then press Windows + R, type in control panel, and hit Enter.
• Go to Mail > Show Profiles. Remove any profiles associated with old or unused accounts and create a new profile for iCloud.
• Check for iCloud Information Services:
• The specific error suggests that Outlook cannot load an information service. Check if the Apple Internet Services are correctly set up:
• In Outlook, go to File > Account Settings > Account Settings.
• Verify if the iCloud account is listed and correctly configured. If it’s not showing, you may need to add the account again.

Additional Suggestions:​

• Disable Antivirus/Firewall Temporarily: Sometimes, security software can block connections between iCloud and Outlook. Disabling it temporarily could confirm this.
• Contact Support: If these steps do not resolve the issue, reaching out to Apple Support or Microsoft Support for further assistance might be necessary.
