To change your password in the Windows version of Outlook:
Open the File menu and click Account Settings → Manage Profiles.
Click Email Accounts.
Choose your account and click Change.
Update your password and click Next.
Click “More Settings…” and if you have a password field in the Outgoing server settings, you will need to update it there as well
Confirm the change and close the Account Settings window.
