Notes: 

  • Outlook on the web relies on the web browser for spell checking, which Internet Explorer prior to version 10 doesn’t provide.

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