Is new Outlook compatible with POP email accounts? New Laptop, old email server, can't set up email account.

New Lenova website, downloaded M365 subscription which included New Outlook only. Trying to set up old POP email account, and keep getting error message. As an additional headscratcher, my year old ASUS laptop with same downloaded M365 subscription works just fine with Classic Outlook and POP email account.

    The new Outlook for Windows does support POP email accounts, but it may require manual configuration. If you are encountering errors while trying to set up your POP email account, ensure that you are entering the correct server settings and credentials. Additionally, if your account is not supported or if there are issues with the email server, you might see error messages indicating that the email server cannot be reached.

    Since your ASUS laptop is successfully using Classic Outlook with the same POP email account, you might want to double-check the settings you used there and replicate them in the new Outlook. If problems persist, consider using the Classic Outlook Profile Setup troubleshooter to help configure your email account properly.

    Hello Dwight,

    Thanks for reaching out I understand how frustrating it can be to set up your email on a new laptop only to find that something as familiar as adding a POP account suddenly becomes more difficult than expected. It’s completely reasonable to feel confused especially since the same Microsoft 365 subscription works smoothly with Classic Outlook on your ASUS laptop. Experiencing errors on a newer device can definitely feel like things are moving in the wrong direction.

    The new Outlook for Windows does support POP accounts, but it handles them differently compared to Classic Outlook. The setup process relies more on your email server’s ability to support modern authentication or secure ports which older mail servers don’t always provide. When automatic setup continues to fail a reliable workaround is to switch to Classic Outlook on your new laptop. You can do this directly from the new Outlook interface by selecting the option to switch to Classic Outlook. Once it opens you can add your POP account using the same server settings that still work on your ASUS laptop. This approach helps you bypass the more restrictive configuration requirements in the new Outlook and lets you work with the older more flexible setup path that is often necessary for legacy servers. You can continue using Classic Outlook on your Lenovo device if your mail server doesn’t meet the modern standards required by the new Outlook allowing you to access your email without further interruptions while still using your Microsoft 365 subscription.

    If you eventually want to move to the new Outlook it may help to check with your email provider to see if your account can be upgraded from POP to IMAP or another modern protocol. Many providers offer this option and it eliminates the compatibility issues that POP accounts commonly run into with the new Outlook environment.

    I hope this answer is helpful if you have further questions feel free to reply back

    Regards,

    Marcelo

    From my experience with New Outlook and POP accounts, you will be far better off if you can get Classic Outlook working on your new laptop.

    For some MS 365 subscriptions, the default installer does not include Classic Outlook. You have to download and install it separately.

    Then configure it to always use Classic Outlook.

    If none of this gets you Classic Outlook on the new laptop, come back and we'll try something else.
