For example, you may modify your email account settings using if you have a new password, your email provider has requested that you do so, or you're experiencing trouble sending and receiving emails. For this, it's necessary to know your email account's account type, incoming and outgoing server names, and SSL and port settings. Then, follow the steps given below: Open Outlook and select file. Use the drop-down under account information to select the account you want to change. Click on account settings. Select the necessary information you wish to change, such as account settings, account name, server settings, change profile, and manage profile.
