FIX: Outlook Error When Sharing Calendar in Windows 10/11

Does your Outlook calendar sharing not working in Windows 10? If you have Office 365 or any other Microsoft Exchange email service, Outlook can be used on the web to share your calendar with others in and outside of your organization.

Depending on the permissions given, others can only view your calendar, edit, or act as your delegate for meeting requests.

If you can’t share your Outlook calendar, it can happen due to configuration or permission issues. Some users have reported that removing current permissions besides the Default and Anonymous resolves the issue.

However, if you still are unable to share your calendar in Outlook, repair Office from Control Panel, and if it fails, download and run the Microsoft Office Configuration Analyzer tool 2.2, which analyzes Office programs for known configurations that can cause issues.

If you don’t have the option to share your calendar (maybe it is grayed out), it can also be because your network admin or IT support set a policy preventing calendar sharing among people in the office.

Fortunately, there are ways to fix the Outlook error when sharing calendar as listed below.
