How do I access the Outlook on the web for Office 365?

While your existing URL for Outlook on the web will still work, we recommend updating your bookmarks to mso.harvard.edu. From there you can launch the Outlook Web App directly from the homepage by clicking the Office 365 Email & Calendar link in the upper right-hand corner of the page.

You can also access the Outlook Web App directly at www.outlook.com/harvard.edu or www.outlook.com/hms.harvard.edu for HMS/HSDM
