I Receive an "Access Denied" Message When I Try to Access My Email.
If you have not registered your cellphone number with Mass General Brigham to allow for phone-based authentication and are attempting to access your email from outside of the Mass General Brigham network you may experience an "Access Denied" message.

Phone-based authentication provides an extra layer of security when accessing certain internet-facing Mass General Brigham applications, such as Outlook Web App (OWA) and PeopleSoft. This feature works by sending a unique confirmation code by text message when you log in. An alternative method is available by phone call.
