InboxRedux — OpenFreeApps

InboxRedux gives you more control over how Outlook on the web displays messages.

Choose between two reading modes:

Preview pane — keep Outlook’s bottom reading pane and resize it to your preferred height.
Accordion Reader — double-click a message to open it inline beneath the selected message, keeping the inbox visible while you read.

In Accordion Reader mode, message text remains selectable for normal copy and paste, Outlook’s built-in message actions remain available, and scrolling continues naturally through the inbox when you reach the top or bottom of a message.

Your reading preference and preview-pane height are stored only in your browser. InboxRedux does not collect, transmit, or share your data.

InboxRedux works with Outlook on the web at Outlook.com, Microsoft 365, and Outlook Cloud.
