If you suspect your email has been hacked, change your password as soon as possible using a trusted device. Choose a strong, unique password that isn't used for any other account and avoid using easily guessed information such as your business name or date of birth.
You should also contact your IT support provider as quickly as possible. They can investigate the account, identify signs of unauthorised access and help secure your wider IT environment. Acting quickly can reduce the opportunity for attackers to access sensitive information or compromise other accounts.
