Question details
The user needs to switch their Outlook Web App interface from the legacy light version back to the standard, modern view.

- Product
- Outlook Web App
- Device & OS
- not provided
- Scenario
- Accessing Outlook via a web browser and finding the interface loaded in the older, simplified layout instead of the standard layout.
- Observed behavior
- Outlook on the web unexpectedly opens in the older light version even when both the web browser and the Outlook account are current and supported.
Ensure you are using a modern, supported web browser such as the latest version of Microsoft Edge, Google Chrome, or Mozilla Firefox before changing the interface settings.
Disable the Light Version Setting in Outlook Options
This is the primary method to switch your interface back to the standard modern view by directly updating your Outlook Web App preferences.
Sometimes the 'Light Version' setting is accidentally checked in your account preferences, which forces the web app to load the legacy interface regardless of your browser's capabilities.
Log in to your Outlook Web App. Locate and select 'Options', usually found in the upper-right corner of the interface.
In the left navigation pane, scroll down and click on 'Outlook Web App version'.
Find the checkbox labeled 'Use the Light Version of Outlook Web App' and clear it.
Click 'Save' at the top of the page. Sign out of your Outlook account completely, and then sign back in to see the standard modern version.

Use Private Browsing and Clear Browser Cache
Use this solution if the light version option is unavailable in settings or if unchecking it did not resolve the problem.

Frequently Asked Questions
Why does Outlook Web App default to the light version?
Outlook may default to the light version if you are using an older or unsupported web browser, if your browser cache is corrupted, or if the 'Use the Light Version' setting was manually enabled in your account options.
What is the difference between the light version and standard version of Outlook?
The light version is a simplified interface designed for slow network connections and legacy browsers. It lacks many modern features found in the standard version, such as advanced formatting, drag-and-drop attachments, and rich calendar views.
Why can't I uncheck the light version box in settings?
If the checkbox is grayed out or unavailable, it usually means your current browser is not fully supported by the modern Outlook Web App. Updating your browser to the latest version or switching to a different modern browser like Edge or Chrome should resolve this.
