  • Go to the Tools menu and click User Accounts.
  • Now click on your email account and check its properties.
  • Click General and make sure your email address is set up in your account control panel. Otherwise, edit and create them.
  • Then click on “Server” and check if the checkbox next to “My server must be authenticated” is checked. If not, check the bug fix.

  • Open Outlook and click Tools.
  • From the Tools menu, select Account Settings.
  • Select your email account from the list and click “Change”. The messaging settings are displayed.
  • Click the “Advanced Settings …” button and select the “Advanced” tab.
  • Change the incoming server (POP3) to port 110.
