As of Sept 6th, 2022, Clemson's Exchange Online environment requires modern authentication in order to access your mailboxes. To continue using Evolution, you will need to make the following settings changes.

Launch the Evolution application. If this is a new installation, follow the prompts below to configure your account. Otherwise, select the menu items File -> New -> Mail Account, click Next, then follow the prompts.

• Enter your name and your primary Smtp address, uncheck Look up mail server details… and click Next.
• For Server Type, select Exchange Web Services.
• Change Authentication to OAuth2 (Office365).
• For Username, specify your username@clemson.edu
• Change Host URL to https://outlook.office365.com/EWS/Exchange.asmx .
  Click the Fetch URL button, providing your password when prompted. This will result in the OAB URL field being populated, which is the address from which the client can download a copy of the Offline Address Book.
• Make sure that Override Office365 OAuth2 settings is checked and populate the Tenant ID and Application ID fields as follows:
  • Application ID: 20460e5d-ce91-49af-a3a5-70b6be7486d1
  • Tenant ID: common

• Finish the New Mail Account Wizard, and you will then be taken to the University’s login page. Authenticate with your credentials and perform Duo multi-factor authentication.
