We asked all staff and students to change their IT password following a serious attempt to attack our systems last weekend. IT Services have expired old passwords, so, if you haven't already changed your password, you'll need to do so straight away so that you can continue to access the network.
Your email password won't change straight away when you've reset your network password. This is due to the ongoing migration to Office 365 that's taking place. Once that work is complete, you'll be able to sign in to email with your new password, but until then you'll need to keep using your old password.
