You can deactivate a user when viewing any page that lists user accounts (active users, logged-in users, or all users, for example), provided the user to be deactivated is shown in the list. You can deactivate user, administrator, and guest accounts; however, if logged in with your account's credentials, you cannot deactivate your own account.
WHY DEACTIVATE AN ACCOUNT? If you need to reduce the number of "active users" in order to add new users (without exceeding the maximum number of active users allowed), you may choose to deactivate some users who are not currently using the application. Deactivating a user account may be preferable to deleting it, because it preserves the user's workspaces for future use.
To deactivate a user account:
HINT: To select multiple users, hold SHIFT or CTRL while clicking another row.
The account is deactivated and the icon to the left of the email address changes to show the user's new status. In the user list, the user's information is dimmed and crossed out.
NOTE: If you attempt to deactivate the administrator account you logged in with, a warning message appears. Logged-in Administrators cannot disable their own accounts.
