Many users rely on SharePoint Online calendars to stay organized and coordinate team schedules. However, syncing issues with Windows 11 can disrupt this smooth workflow. These problems can be frustrating but are often fixable with a few simple steps.
This article walks you through easy and clear solutions to resolve SharePoint Online calendar sync issues on Windows 11. Each step is explained in detail, making it accessible even if you are not very technical.
By following these instructions, you can quickly restore synchronization and ensure your calendar stays up to date. Let’s get started with some quick notes before diving into the troubleshooting steps.
Understanding why syncing fails will help you avoid future problems and optimize your SharePoint experience.
Quick Note: Prerequisites and Initial Checks
Before attempting any fixes, make sure you have these basics covered:
- Reliable Internet Connection: Calendar sync requires a stable internet connection. Check your network to avoid connectivity-related issues.
- Correct Permissions: Ensure you have the necessary permissions to access and edit the SharePoint calendar.
- Latest Windows Updates: Windows 11 updates often fix bugs related to apps and syncing. Verify your system is up to date via Settings > Windows Update.
- Office 365 and Outlook Updates: Since SharePoint calendars often sync with Outlook, having the latest versions is important. Update Office apps through Microsoft 365 or Microsoft Store.
- Signed-in Account Matches: The account you use on Windows and in Office apps should be the same as your SharePoint Online account.
Step 1: Restart Your Computer and Applications
Often, simple restarts can clear temporary glitches causing sync failures. Restart your Windows 11 PC and then reopen Outlook or the application you use to view the SharePoint calendar.
This helps refresh background services and clears any stuck processes that might block syncing.
Step 2: Verify SharePoint Calendar Connection in Outlook
If you access your SharePoint calendar through Outlook, ensure it is properly connected:
- Open Outlook and go to the Calendar view.
- Look for your SharePoint calendar under Other Calendars.
- If it’s missing, add it again by visiting the SharePoint site, clicking the calendar, and selecting Connect to Outlook.
This step is important because sometimes the calendar link can break or disconnect, preventing sync.
Step 3: Clear Outlook Cache
A corrupted cache can cause syncing issues. Clearing the Outlook cache can resolve this:
- Close Outlook completely.
- Press Windows + R to open the Run dialog.
- Type
%localappdata%MicrosoftOutlookand press Enter. - Delete the files inside this folder. Don’t worry, this only clears temporary data.
- Restart Outlook and check if the calendar syncs.
Clearing the cache forces Outlook to rebuild data, often fixing corrupted sync information.
Step 4: Check and Repair Office Installation
If the problem persists, repairing your Office installation can fix any corrupted files affecting SharePoint calendar sync:
- Open Settings > Apps > Installed apps.
- Find Microsoft Office or Microsoft 365 in the list.
- Click Modify.
- Select Quick Repair first and follow the prompts.
- If that doesn’t help, repeat and choose Online Repair (this takes longer but is more thorough).
Repairing Office fixes damaged program files that may interfere with syncing.
Step 5: Use Microsoft Support and Recovery Assistant
Microsoft offers a free tool called Support and Recovery Assistant (SaRA) that can diagnose and fix Outlook and Office 365 sync issues automatically:
- Download SaRA from the official Microsoft website.
- Run the tool and select the problem related to Outlook or Office365 calendar syncing.
- Follow the on-screen instructions to allow the tool to detect and fix issues.
This automated option is helpful for users who prefer a guided troubleshooting process.
Step 6: Confirm Time and Date Settings
Incorrect system time or timezone can cause sync conflicts. To check and fix:
- Go to Settings > Time & Language > Date & Time.
- Make sure Set time automatically and Set time zone automatically are enabled.
- If not, enable them and restart your PC.
Accurate time settings are essential because SharePoint and Outlook use timestamps to sync calendar events correctly.
Alternative Method: Sync via Outlook Web App
If syncing through the desktop Outlook app fails, try using the Outlook Web App (OWA) as a temporary workaround:
- Open your browser and go to Outlook Web App.
- Log in with your Microsoft 365 credentials.
- Access your SharePoint calendar under calendars linked to your account.
This method ensures your calendar is accessible and up to date while you troubleshoot desktop syncing.
