    Hello Claudio Palagano

    Thank you for reaching out to Microsoft Q&A.

    The ports and server addresses you tried are perfectly correct for a traditional POP setup! However, the reason you are getting this error is that Microsoft recently disabled "Basic Authentication" for all personal Outlook accounts. They now require a newer security standard called "Modern Authentication." 

    To connect your account, you must let the system auto-configure it as an Exchange account. Since Exchange uses an .ost(offline cache) file instead of the .pst file you want, you can let Outlook set up the modern connection, and then use a background rule to instantly funnel all your mail into a local PST file, perfectly mimicking the old POP behavior. 

    Here is how to set up the workaround: 

    Step 1: Auto-Configure the Account 

    • Go to File > Add Account
    • Type your @outlook.com email address and click Connect(Note: Do not check the "set up manually" box). 
    • A modern Microsoft login window will appear. Enter your password to successfully add the account. 

    Step 2: Create a Local PST File 

    • Return to your main Outlook screen. 
    • On the Home tab, click New Items > More Items > Outlook Data File
    • Name the file (e.g., "Claudio Outlook PST") and save it to your computer. This creates your new local PST inbox on the left sidebar. 

    Step 3: Create the Mimic Rule 

    • Click on your new @outlook.com Inbox. 
    • Go to the Home tab and click Rules > Manage Rules & Alerts
    • Click New Rule. Under "Start from a blank rule," select Apply rule on messages I receive and click Next
    • Do not check any conditions on the first screen (this ensures the rule applies to all emails). Click Next, and click Yes on the warning pop-up. 
    • On the Actions screen, check Move it to the specified folder
    • Click the underlined word Specified at the bottom, select the Inbox of your new PST file from Step 2, and click Finish then Apply

    Now, every time an email arrives at your Outlook address, Classic Outlook will instantly move it into your local PST file, exactly as if it were a POP account. 

    I hope this helps you get your inbox set up exactly how you prefer! If you have any updates regarding the issue, please feel free to share them with me.

    It seems like you are experiencing issues with importing a PST file into Outlook Classic, particularly with your Outlook email account. Here are a few troubleshooting steps you can consider:

    1. Check Account Settings: Ensure that your Outlook account settings are correctly configured for the Outlook email account you are trying to use. This includes verifying the incoming (IMAP/POP) and outgoing (SMTP) server settings.
    2. Ports and Encryption: Make sure you are using the correct ports and encryption methods:
      • For IMAP: Use port 993 with SSL/TLS for incoming mail (outlook.office365.com).
      • For SMTP: Use port 587 with STARTTLS or port 465 with SSL/TLS for outgoing mail (smtp.office365.com).
    3. Test Connectivity: You can use the Telnet Client tool to test the connection to the SMTP server. This can help determine if there are any network issues blocking the connection.
    4. Create a New Profile: If the problem persists, consider creating a new Outlook profile. This can sometimes resolve issues related to corrupted profiles.
    5. Check for Updates: Ensure that your Outlook Classic is up to date, as updates may contain fixes for known issues.

    If you continue to encounter problems, you may want to consult the official Microsoft support documentation or community forums for additional assistance.
