If your administrator has configured your system to notify when your password is about to expire, you will receive an email a number of days prior to the expiration date. The exact date on which the notification is sent depends on how your system is configured. You will also receive an email on every subsequent day until you reset your password or until your password has expired.
If your password is linked to other applications, the email will include a list of all the other applications that will be changed when you reset your password.
NOTE: This might include the password you use to sign in to your corporate network.
To set a new password, refer to How do I change my password if I forget it or need to reset it? The process for changing an expired password is the same as resetting a password if you've forgotten it.
