Using Outlook Web App on desktop and laptop computers

  • Best: All features will work.

  • Good: Most features will work.

  • Light: The browser will display the light version of Outlook Web App.

Note:  In previous versions, Outlook Web App had built-in spell checking. In the latest release, Outlook Web App relies on the web browser for spell checking, which Internet Explorer prior to version 10 doesn’t provide.

Note: Office 365 users will be limited to the light version of Outlook Web App when using Internet Explorer 8. Users whose mailboxes are on a locally managed Exchange server will continue to see the standard version of Outlook Web App when using Internet Explorer 8, but may experience slow or otherwise unsatisfactory performance.
