Which tool allows access to Outlook information from various devices without incurring additional server costs?

The correct choice allows users to access Outlook information seamlessly across various devices without needing additional server resources. Microsoft Exchange serves as an email server and provides a collaborative platform that facilitates email, calendaring, contacts, and tasks management. It is specifically designed to work with Outlook, enabling users to sync their information on multiple devices, such as smartphones, tablets, and computers.

By utilizing Microsoft Exchange, organizations can manage email and other shared information in the cloud or on-premises without the necessity of deploying additional infrastructures or incurring extra server costs associated with maintaining individual email systems for each device. This centralized approach enhances accessibility and efficiency, ensuring that users can connect with their Outlook data anytime, anywhere, using various devices.

In contrast, other options like Microsoft Access and Microsoft PowerPoint do not serve the function of email management or provide the same level of multi-device access for Outlook information. Google Sheets, while collaborative, is focused on spreadsheet functionality and does not directly interface with Outlook for email or calendar synchronization.
