Modern Authentication Microsoft 365 Email and Calendaring Setup
On this page:
Context
Outlook for PC and Outlook for Mac do not generally require intervention to use Modern Authentication. They will choose Modern Authentication automatically. Mobile device apps and other clients more frequently require you to delete and re-add your account. Deleting and re-adding does not affect any of the data stored on the server, no data is at risk of loss. After you re-add, you will be required to authenticate through Touchstone.
Below are steps for getting up and running on the most popular mail clients in use by the MIT community.
For more information on the switch to requiring Modern Authentication (Touchstone), see: Why can't I login to my Microsoft 365 account using just my username and password?
