Hello, I currently run XP on my home PC and intended to upgrade to a machine operating with Win 8.1. However got wind that 8x does not support POP3. I am not a tekky so don't really know what POP3 is other than my current home email uses it. Seen other discussions on this issue including how to get around this but all looks very complicated. So the question is does Win 7 support POP3 email? Regards.
I think you're using some incorrect terminology, which might add to the confusion.
From what you say, you're most likely using "Outlook Express" from Microsoft in WinXP. This is a POP3-style email client program. There are a number of other similar (but different) email software program products (not from Microsoft) that can also be configured to use the POP3 protocol like Outlook Express. Essentially your email service (commonly your ISP, but it can be a 3rd-party email service from anyone) provides incoming (POP3) and outgoing (SMTP) email servers. Any email for you is received by the POP3 server and then your email client program (e.g. Outlook Express) checks in to the POP3 server for new email, and downloads that email to your local PC. Typically the email is then deleted from the POP3 server, so that it now lives only on your local PC (typically in the INBOX initially, but you can then do whatever you want with it), but this is configurarble.
In reverse, when you want to send new outgoing email (or reply to an email you received) you compose it using your email client software (e.g. NEW MESSAGE, or REPLY, etc.) and then typically push the SEND button. This contacts the SMTP server of your mail service, and your outgoing email is sent up to the SMTP server from where it then gets sent to the ultimate recipient.
Now... starting with Win7 Microsoft removed Outlook Express from the standard operating system where it had lived seemingly forever (certainly it was in WinXP). Instead, they "encourage" you to use Windows Live Mail which is of a COMPLETEY DIFFERENT design notion. It's not that the operating system doesn't support the POP3/SMTP email protocol. It's just that Microsoft does not provide a gratis POP3-style email client like Outlook Express anymore.
So, if you want to continue using this style of email program you need to look elsewhere. A highly regarded free POP3-style email program is available from Mozilla (same people that provide Firefox), named
THUNDERBIRD. It's not the exact same as Outlook Express of course, but it looks and works very similarly. Thunderbird is an HTML-based email program (for composition and presentation), which again you'll find very similar to Outlook Express.
I myself use another POP3-style email client program named
AGENT (from Forte). I've been using it forever, and continue to use it in Win7 (where of course it still works perfectly). It's a text-based email program for composition, although it does "render incoming email which is in HTML".
Or, you can investigate Windows Live Mail as has been suggested, or anything else. But you won't find Outlook Express anymore.
