If you have to change your email password, you’ll need to do that with your email provider (for example, Microsoft 365, Gmail, Yahoo, iCloud, Xfinity, or a corporate Exchange server). Then you’ll need to update the password in Outlook, the program that displays your email messages and allows you to read, reply to, and organize them.
When should I change my password with my email provider?
Change your password when:
You think someone has stolen or gained access to your email account password
Your email provider has sent you a password reset link
You forgot your email account password
Change your password with your email provider
See the following sections for instructions on changing your email account password for several major email providers. If your email account provider isn't listed, contact your admin or the email provider's help desk.

Other email accounts will require you to change your email account password on the website for the account provider. For example, to change the password for an Xfinity account, go to the Xfinity website and follow the prompts. Many email account providers have slightly different steps for changing a password.
