Solution-1: Check Email Username & Password

Step 1:Open a browser on the computer and log in to your Webmail account.

Step 2:Navigate to the settings menu and open the mail server settings.

Step 3:When you enter the wrong username and password, you cannot access the emails.

Step 4:See if the CapsLock and the NumLock are enabled and then enter the correct username and password for the server authentication.
