Symptoms

When a user opens Outlook Web App in a Microsoft 365 environment, Outlook Web App opens only in the light version. Therefore, the user doesn't have access to the comprehensive set of features that are available in the standard version of Outlook Web App. This occurs even though the user has a web browser that supports the comprehensive feature set in the standard version of Outlook Web App.

Other users in your organization don't experience these symptoms. When other users open Outlook Web App, they have access to the comprehensive set of features that are available in Outlook Web App.

Cause

This scenario occurs if the user unintentionally selects the Use the blind and low vision experience option in Outlook Web App.

Resolution

To resolve this issue, follow these steps:

  1. Make sure that the user is using a supported web browser.

  2. In Outlook Web App, select Options.
