You can change the password on any of your email
accounts whenever required. It is useful to occasionally do this to maximize
your email security. You should always change your password if you
think someone else has access to your account.
Note: Make sure that you change the password
in your offline email application as well, or you will not be able to upload
or download email to this account.
To change an email accounts password:
Click on the Add / Remove accounts link in the Mail Menu area.
Click on the Change Pass button next to the required email address.
Enter the new password in the New Password field.
Click on the Change button.
Your password has now been changed for that account.
