Limited Functionality in Classic / Legacy Outlook

Issue/Question

When using Classic Outlook (Windows) or Legacy Outlook (macOS), I encounter errors and issues with functionality. How do I resolve this?

Environment

  • Classic/Legacy Outlook
    • Windows 10/11
    • macOS

Cause

Microsoft will end support for Legacy Outlook for Mac on October 1, 2025, and Classic Outlook for Windows on October 1, 2026. In preparation for these changes, Microsoft has begun depreciating services used by Legacy / Classic Outlook, particularly Exchange Web Services (EWS).

WKU Email accounts should be accessed from Outlook Web Access, or via the New Outlook application.
