How to Fix Calendar Not Syncing with Exchange on macOS Ventura

Can’t figure out why the Calendar app is not syncing with Microsoft Exchange on macOS Ventura?

Mac users are complaining about a bug with the Calendar app that prevents them from viewing added events on Microsoft Exchange. 

Based on the reports, users can see all added events using the Calendar app on their iPhones but not on their Macs. 

This can be annoying since you’ll have to switch devices to check for upcoming meetings, schedules, and reminders. 

To help out, we’ve decided to make a guide for fixing the Calendar if it’s not syncing with Microsoft Exchange on macOS Ventura. 

Let’s get started!

1. Check Apple Servers. 

Whenever you encounter syncing problems on your Mac, you should always check the status of Apple’s servers. 

If there are ongoing issues on Apple’s end, online features on your Mac may act up. 

To confirm this, head to Apple’s server status page and check if there are problems with iCloud or Mail. 

Sadly, there’s nothing you can do if the problem is server-related. On the other hand, you can head to the next solution if Apple’s servers are working. 

2. Check Microsoft Servers. 

If there are no issues with Apple’s servers, there’s a good chance that Microsoft is experiencing problems on their end. 

Head to Microsoft’s system status page to confirm if there are outages. 

Similar to Apple, problems with Microsoft’s servers can only be addressed on their end. If the servers are down, the only thing you can do is wait. 

But if there are no issues with the servers, you can proceed to the next step. 

3. Restart Calendar. 

One of the simplest things you can do to address this problem is to force restart the Calendar app. 

This should prompt the app to fetch the most updated data from your account, which should reflect the events you’ve added using Microsoft Exchange. 

Check out the steps below to restart the Calendar app: 

1. On your keyboard, press Command + Space to open Spotlight Search. 
2. Look for Terminal and hit Return to open it. 

3. Inside the Terminal, copy the commands below one by one and hit Return after each command. 

launchctl stop com.apple.CalendarAgent

launchctl start com.apple.CalendarAgent

Once done, open Calendar on your Mac to check if the problem is solved.

4. Re-Add Your Exchange Account. 

Removing your Exchange account from the Calendar app and adding it back afterward can also resolve this problem. 

This should refresh your user data and force the Calendar app to update the information it currently has. 

See the steps below to guide you through the process: 

1. Open Calendar on your Mac. 
2. Now, click on the Calendar tab in the upper left corner of your screen. 
3. Choose Accounts from the drop-down menu. 
4. Click on Internet Accounts on the side menu. 
5. Next, click on your Microsoft Exchange account. 

6. Click on Delete Account. 

7. Confirm your action by clicking OK in the dialog box. 

After 2 to 3 minutes, add your Microsoft Exchange account and check if you can now view all your events. 

5. Enable Calendars Sync on Microsoft Exchange. 

If the Calendar app is not syncing with Microsoft Exchange, there’s a chance that the sync feature is disabled on your system preference. 

To verify this, follow the steps below: 

1. First, click on the Apple icon in the upper left corner of your screen. 
2. After that, click on System Settings. 
3. Access the Internet Accounts tab from the side menu. 
4. Find your Microsoft Exchange account and click on it. 

5. Click on the toggle switch beside Calendars. 

Once done, restart the Calendars app and check if the problem is solved.

6. Restart Your Mac. 

You can try restarting your Mac if you still encounter sync problems with the Calendar app and Microsoft Exchange. 

This should reload your system resources, resolving temporary errors that may have occurred during use. 

Restarting your Mac should also clear its memory, flushing corrupted data from your apps. 

Here’s how you can restart your Mac: 

1. Click on the Apple logo in the upper left corner of your screen. 
2. Now, choose Restart from the drop-down menu. 
3. Confirm your action by clicking Restart again. 

Go back to the Calendar app afterward to check if the problem is solved.

7. Update Your Mac. 

If the Calendar app is still not syncing with Microsoft Exchange, we suggest updating your Mac. 

The version of macOS you’re using might have an underlying issue that causes problems with the calendar. 

See the steps below to update your Mac: 

1. First, open the Apple Menu in the upper left corner of your screen. 
2. Go to System Settings. 
3. Navigate to General > Software Update. 
4. If a new version is available, click on Update Now or Upgrade Now. 

Go back to the Calendar app after the update to check if the problem is solved.
