Email client programs such as Microsoft Outlook are a convenient alternative to access your messages through an email website. Client programs download messages from email servers and store them in local folders on your computer, allowing you to send and receive all mail in the client program itself. Client programs of the Outlook type must be configured with the email login information to work properly. Therefore, if there is a technical problem that prevents you from accessing your emails, you will often see messages indicating that Outlook can not verify the username and password that you have saved in your Outlook account.
Check the username and password settings of Outlook. Go to the Outlook account manager, open the “Tools” menu and click on “Accounts”, “Account settings” or “Email accounts”, depending on the version of Outlook you are using. In the accounts window, select the account you are trying to access by clicking on it once. Verify that the username is entered in the appropriate field, also make sure to enter only the username of your email and not the full email address (such as “JohnSmith” instead of “email@example.com”) . Also make sure that the password is entered in the password field (usually represented by a series of points). Re-enter the password just in case, and make sure the “remember password” field is checked. Try to check new messages again. If Outlook still does not accept your username and password, you need an additional solution to solve the problem.
Check if your Internet connection is working. Often Outlook will show you a pop-up window that will ask you to enter the password only because it can not detect an Internet connection for your use. Display your Internet browser and review a few web pages. If you see any kind of connection error, contact the technical support department of your Internet Service Provider (ISP) and get a representative to help you solve the connection problems. If the browser displays web pages without any connection error messages, then you already know that your Internet connection is working and, therefore, Outlook should be able to connect to it. If Outlook still asks for your email username and password, proceed to Step 3.
Contact the technical support department of your email service provider. Get a representative to verify if you are using the correct email password, or even to reconfigure a new password and enter the new password in Microsoft Outlook. If you verify that you are using the correct password for the Outlook email account and still do not accept your username and password, ask your email service provider to troubleshoot your Outlook account, or contact support Microsoft technician to check if there is a possible software malfunction with Outlook.
