This question asks to identify the application that is NOT developed or owned by Microsoft from the given list. Let's analyze each option:

Microsoft Application Overview

• SharePoint: SharePoint is a web-based collaborative platform developed by Microsoft. It is often used for internal business websites, document management, and content sharing.
• OneNote: OneNote is a digital note-taking application created by Microsoft. It allows users to create notes, drawings, screen clippings, and audio commentaries. It's available across multiple platforms.
• Outlook: Microsoft Outlook is a personal information manager and email client from Microsoft. It is widely used for managing emails, calendars, contacts, and tasks.
• Gmail: Gmail is a free, advertising-supported webmail and cloud storage service developed by Google. It is a direct competitor to Microsoft's Outlook email service.

Identifying the Non-Microsoft Application

Based on the analysis above:

• SharePoint is a Microsoft product.
• OneNote is a Microsoft product.
• Outlook is a Microsoft product.
• Gmail is a Google product, not a Microsoft product.

Therefore, the application that is not a Microsoft application is Gmail.
