If you are having problems logging into Blackboard, the most common cause will be an expired account password. You can check this below by entering your username and clicking submit (a password is not required).
If you have recently reset your password via the Webmail system or from the desktop login prompt and you still get an error when trying to log into Blackboard, the problem may be due to a synchronisation problem.
In very rare cases a legitimate user may not have an account on the Blackboard system, the test below will also identify such cases.
