Select the email account that you wish to edit and click "Change..."
Change "Outgoing mail server (SMTP):" to smtp.johnshopkins.edu. NOTE: Never check "Log on using Secure Password Authentication (SPA)" or authentication will not work.
Click "More Settings..." to configure Outlook for SMTP authentication and SSL
Click on the "Outgoing Server" tab and check "My outgoing server (SMTP) requires authentication. If your incoming mail server uses your JHED LID and JHED password, then you can select "Use same settings as my incoming mail server". Otherwise, select "Log on using" and enter your JHED LID and JHED password in the text boxes. NOTE: Never check "Log on using Secure Password Authentication (SPA)" or SMTP authentication will not work.
Click on the "Advanced" tab and check "This server requires an encrypted connection (SSL)" under the "Outgoing server (SMTP):" option. NOTE: Although in Outlook the option is advertised as SSL, the email client is really using TLS when the port being used is port 25. When using any other port than port 25, the email client uses SSL. So, when reading documentation referring to TLS, this pertains to Outlook using SSL on port 25.
Click "Ok", then "Next", and then "Finish" to complete the changes
You must then restart Outlook in order for the changes to take effect and in order to send email using the new settings
