Changing a username will not generate an email notification. Since only subscription administrators may change this field, please make sure affected users are notified prior to the change. The change will be stored in the subscription's revision history.
Ownership of work items, custom views, notification rules, and user settings will not be affected when a username is changed. When a user owns a work item, the display name will be shown. If that user has no display name set, the first name and first initial of the last name will be shown. If these fields are also blank in the user's settings, the portion of their username before the '@' symbol will display.
