Whether a contact has a new email address or they prefer to use a different one than what is currently being used, changing a contact's email is simple; however, there are two important things to keep in mind:
Changing an email address within their contact profile does not change the contact's portal username/login.
The contact will still be required to use the old email address to log into their portal.
The old email address will continue to receive email notifications for new tasks assigned to the portal (if enabled), weekly digest emails (if enabled), and new message email notifications on file request tasks.
How to change a contact's email address
Within the Speaker or People module select the open (maximize) icon to the left of the contact record that you want to change an email address for.
Navigate to the "Edit" tab at the top of the screen.
Click into the "Email" field and change the email address. Click out of the textbox to save your change.
