Open an item in a separate window

By default, you read and create items in Outlook Web App either in the reading pane, or in a window that overlays the main window. But that isn’t always what you need. Sometimes you need to be able to view or edit an item in a separate window.

For most items, to open them in a separate window, look for the pop out icon  in the upper corner of the item you’re working on. Click it to open that item in a separate window.

To open a message that you’re reading in a separate window, click the extended menu icon  and select open in separate window.

Working offline

Offline access lets you use Outlook Web App on your laptop or desktop computer when you’re not connected to the Internet. For information about setting up offline access, see Using Outlook Web App offline.
