Can a user change their email address?
This article explains how to change a user's email address in ExpensePlus.
Email addresses are used to identify user accounts in ExpensePlus.
A user cannot change their own email address. However, another user with the correct system permissions (such as a Finance Team user) can update someone's email address on their User Profile for them, within the User Settings screen.
