Overview

As of July 18th 2023, the Thunderbird configuration for exchange online needs to be updated.

Procedures

1. Open Thunderbird.
   
   
2. Near the far top right corner of the Thunderbird window, click the three horizontal line icon button, and click on Account Settings in the popup dropdown menu.
   
   
   [Selecting Account Settings in popup dropdown menu.]
   
   

3. In Account Settings window, you will now see your RPI email now listed. Select Server Settings (associated with your RPI email and type in the following:

   a. Server Name: outlook.office365.com

   b. User Name: Your RPI Email Address

   c. Port: 993

   d. Connection security: SSL/TLS

   e. Authentication method: OAuth2

   
   [Typed in server name, port, and user name in associated text boxes. Changed connection security and authentication method settings.]
   
4. In Account Settings window, select Outgoing Server (SMTP) in the lefty column.
   
   

5. Verify that the Outgoing Server for your RPI Email has the following configuration:

   a. Description: RPI Email (you can type anything for the description)

   b. Server Name: smtp.office365.com

   c. Port: 587

   d. Connection security: STARTTLS

   e. Authentication method: OAuth2

   f. User Name: Your RPI Email Address
   
   

6. Go to the Inbox for your RPI email account (found on Thunderbird's home screen)
   
   
7. A popup window should now appear asking you to sign in to your RPI Microsoft Account. (This window might appear behind the main Thunderbird window, so you may need to go looking for it.)
   
   [Typed in email when prompted by the Microsoft sign in popup window.]
   
   
8. Once you've entered both of these things, you should then see a prompt from the Duo Two-Factor-Authentication system, either asking for a second password or telling you that a notification has been sent to your mobile device:
   
   
   [Popup window indicating DUO sent a notification to mobile device.]
   
   
9. Having made it through the Duo system, you'll be asked if you wish to Stay signed in? Personal preference if you want - Check the box that says Don't show this again and click on the Yes button.

Having completed the configuration and authentication steps, you should now double-check that everything is working properly. If not, please submit a service ticket at https://itssc.rpi.edu for further assistance.
