    Hi @Killingworth

    It can be quite frustrating to get stuck on a login error when you're just trying to get your email up and running.

    Based on the information provided, I understand that you are trying to set up your email via POP, but you keep receiving an error message stating that the system cannot log into the incoming POP server.

    To help me investigate this further and provide the correct settings, could you please clarify a few details?

    -Are you trying to set up a Microsoft account (like @outlook.com, @hotmail.com, or a Microsoft 365 business account) or an account from a third-party provider?

    -If you are using a Microsoft account: Standard POP login with just a password is often blocked. So, if you are using a third-party provider: I will need the specific name of your provider to give you the exact server addresses, port numbers and encryption methods (SSL/TLS) required.

    Please let me know which provider you are using, and I’ll guide you through the next steps!

    Use the following checks and steps to resolve the POP login error in Outlook for Windows (Classic):

    1. Verify email address, username, and password
      The most common cause is incorrect credentials. Ensure:
      • The full email address is used as the username (for example, ******@contoso.com).
      • The password is typed correctly (case-sensitive).
        If Outlook shows a repeated password prompt, confirm the password directly by signing in to the provider’s webmail.
    2. Confirm POP server name, port, and encryption
      POP connections require the exact incoming server, port, and encryption method provided by the email host. For Microsoft 365 work or school accounts, the documented POP settings are:
      • Incoming POP3 server: outlook.office365.com
      • Port: 995
      • Encryption: SSL
        Make sure these values are set in the account’s POP settings in Outlook if using Microsoft 365 for business.
    3. Ensure SSL is required for POP
      POP over port 995 requires SSL:
      • In the account’s advanced settings, enable Require SSL for incoming mail. If SSL is not enabled while using port 995, the server will reject the connection.
    4. Check for known POP issues in Outlook/Windows
      On some Windows versions, POP/SMTP connections can fail if certain options are not selected. For example, in older Outlook/Windows combinations, not saving the password can cause repeated prompts and prevent logging on to the POP server. Ensure the account is configured to remember the password so Outlook can send the credentials correctly.
    5. Recreate the POP account with correct settings
      If settings were changed multiple times, remove the POP account from Outlook and re-add it using the correct server name, port, encryption, and saved password. This often clears corrupted profile settings.

    If the POP server is not Microsoft 365 (for example, another provider), obtain the exact POP server name, port, and encryption from that provider and configure Outlook to match.
