How to fix?

Answer 1

Hello Joe Vance, thank you for posting in the community.

To better understand the issue, could you please confirm whether you are using Classic Outlook or the New Outlook experience?

As a first step, I recommend removing the existing Google Calendar ICS subscription from Outlook. In Outlook, go to File, then Account Settings, open Account Settings again, and select Internet Calendars. Locate the Google Calendar subscription, remove it, and then restart Outlook.

After restarting, re-add ICS using the appropriate method based on the Outlook version you are using. See the steps on this article Subscribe to your Google Calendar.

 

Kind regards,

To address the issue of Outlook calendar not syncing with Gmail calendar and the slow shutdown of Outlook accompanied by the error message "Internet calendar subscription error 0x80004005," you can try the following steps:

1. Check Internet Connection: Ensure that your internet connection is stable, as a poor connection can affect syncing.
2. Remove and Re-add the Calendar Subscription: If you have subscribed to an Internet calendar, try removing it and then re-adding it. This can sometimes resolve sync issues.
3. Update Outlook: Make sure that your Outlook application is up to date. Updates often include bug fixes that can resolve syncing issues.
4. Repair Outlook: Use the built-in repair tool in Outlook to fix any potential issues with the application. You can find this option in the Control Panel under Programs and Features.
5. Check Permissions: Ensure that you have the necessary permissions to access the calendars you are trying to sync.
6. Disable Add-ins: Sometimes, add-ins can interfere with the normal operation of Outlook. Try disabling any unnecessary add-ins to see if that resolves the issue.

If the problem persists after trying these steps, consider checking the official Microsoft support documentation for more detailed troubleshooting steps related to Outlook performance and syncing issues.
