It is possible to change the email address of a workspace user, this article describes how it is done.
Changing a users email address has to be done through the main user dashboard or the by an admin in the workspace.
Making the change in the main user dashboard will change it globally across all workspaces under the particular customer account, where as changing the email in a workspace will only apply to that specific workspace.
Changing a users email immediately logs the user out from all workspaces that the change impacts and disables all previous login links. This occurs due to security reasons to prevent the the owner of the old email to access the workspace.
In a workspace an admin user cannot change their own email, however they have the ability to change any other users email address.
To change a users email in the workspace, the admin must open the users profile from the user management:
With the profile modal open, select 'Edit profile':
Change the Email address and hit 'Save'.
Once the change is saved the user management view will display the new email address of the user.
