If you have changed your email password for third-party providers (such as Gmail, Yahoo, etc.), and now you need to update the new password in Outlook, you can just open and run Outlook. Outlook will then ask you for the updated password in a pop-up dialog.

However, if there are no dialog boxes popping up, you can try to update the password here:

1. Click File > Info > Account Settings > Manage Profiles to open the Mail Setup dialog box. Then click Email Accounts.

2. In the Account Settings dialog box, please click to highlight the email account whose login password you will update, and then click the Change button. See screenshot:

3. In the Change Account dialog box, please clear the old password from the Password box, type the new login password into it, and click the Next button.

Note: If you do not want to test the login password and other email account settings, please uncheck the Automatically test account settings when Next is clicked option.

4. Now the Test Account Settings dialog box comes out. After testing completes, please click the Close button.

5. Click the Finish button to save the new password, and then close the Account Settings dialog box.

Up to now, the specified email account’s login password has been updated in Outlook.

Automatically reply with the default email account in Outlook

In general, Outlook can identify the email account that the active email belongs to, and then reply with this email account automatically. However, with Kutools for Outlook's Always reply with default account option, no matter which email account the active email belongs to, it will be replied with the default email account in you Outlook.

Sometimes, you may set a password to access one email account’s Outlook Data File (.pst) in Outlook. To change this kind of accessing password in Outlook, please do as follows:

1. Click File > Info > Account Settings > Account Settings to open the Account Settings dialog box.

2. In the opening Account Settings dialog box, please shift to the Data Files tab, then select an email account that you want to change the password of, and click Settings. See screenshot below:

Note: Make sure the extension of the file listed in the Location column that you select is .pst, since you can only set and change passwords for an Outlook Data File (.pst).

3. Now please click the Change Password button in the Outlook Data File dialog box. See screenshot below:

Note: You cannot see the Change Password option if you selected an Offline Outlook Data File (.ost) file since there is no way to set a password for an .ost file.

4. In the popping up Change Password dialog box, please type the original password into the Old password box, and type the new password into both New password box and Verify password box. If you did not set a password for the selected .pst file, you can just leave the Old password box blank.

Note: It’s optional to check the Save this password in your password list option in the Change Password dialog box.

5. Click OK > OK > OK in the dialog boxes to save the new password.

So far the password for accessing Outlook data file of the specified email account has been changed.

Note: This method can only add or change accessing password to the Outlook data file (.pst) of POP3 email accounts. After you set a password on your Outlook data file, do keep the password in mind, since there is no way to retrieve the password.
