    I have used MS Outlook for likely 15+ years. I still use a Pop3 setup. Back when I used an iPhone (3.5+ years ago), I could access my e-mail on the iPhone when traveling, delete most of the mails, and still be able to access those (phone) deleted mails when I returned to my PC at home. When I switched to an Android phone, I discovered that it needed an imap account for it to work on the phone. Due to research that I do, I want to preserve certain (now a couple of thousand) e-mails on my PC. So, I do not use e-mail on my phone as deleting it on my phone would delete it everywhere....so I'm told. I want everything on my PC, where I regularly back up, and will cull it from there. So, I stay with pop3. 'Course, now that I'm old, I can wait until I return home to read my e-mails, but phone access would be convenient.
    Now, the additional issue is how to save all of those .pst e-mails on my PC to a readable format if and when I leave MS Outlook.

    Thankyou Leo for your great videos.
    My son is an IT person; me, not so much. Some years ago, he set up Thunderbird for me and it sounds like he used IMAP, because when I deleted emails on my PC, I still had copies on my other devices. I don't use Thunderbird now that I have Gmail, but at the time, I found it annoying because I needed to delete the messages twice. In hindsight, I can see not losing your original, has a lot of advantages.

      I am also interested in this response. In addition, some of my outlook accounts resend messages to the extent I wake up to 300-400 new messages each day.

    Hi Leo. A nice simple and clear explanation. But a bit too simple re IMAP itself and also re IMAP vs POP3.
    1. IMAP is a 2-way sync, unlike POP3's one-way retrieval.
    2. IMAP does a 2-way sync on an entire collection of folders and subfolders, unlike POP3's one-way retrieval of Inbox only. This would matter a lot if a user currently has a whole folder tree of e-mails on the server, which a Webmail user could easily have done over time, as part of organizing his/her e-mails.
    3. Though a POP3 mail client normally deletes the retrieved e-mails from the server, most POP3 mail clients do have the option of leaving mail on the server. Furthermore, some mail servers have an option to ignore a mail client's "delete from server" setting.

    Excellent video. If I signed into my outlook email using SMTP via a third party app as provided on my tablet, will the signed in activity show on my Microsoft / outlook account login activity?

  • @NoEgg4u

    I used to use Outlook 2007, configured with POP3.
    That version of Outlook had an option to leave the e-mail on the server (download, but do not delete).
    I do not know what current versions of Outlook have, or what other e-mail clients have. But if I had to guess, I would say that they, too, can be configured the same way (to not delete your messages from the e-mail server).
    I once heard that POP3 does its business in the clear, whereas IMAP creates an encrypted tunnel between you and the e-mail server -- making it a more secure choice for exchanging e-mail messages between you and the e-mail server. I might be mistaken, and not interested enough to search for the answer. Maybe someone else can elaborate.

    • @askleonotenboom

      Most POP3 clients support the "leave messages on server" option. Both POP3 and IMAP (and SMTP) can be configured to use (or not) an encrypted connection. It's all part of how you configure the client. Look for things like "SSL" and "TLS" options. Those are encrypted.

    Which one is best for replying to emails?
    Does replying to an email from an email address where the original email was routed to a new email address through pop3 IMAP or SMTP affect domain reputation because it's sent from a different address?

    • @askleonotenboom
      @askleonotenboom  5 месяцев назад

      SMTP is used for sending. IMAP and POP3 are all about recieving.

      If you're online this doesn't apply. If you're using a desktop email program, then it's part of the account configuration.

      You haven't told me what account this is for. In general you can either wait until you get your phone, or do some kind of password recovery (forgot password).

      Web-based email uses none of them. They have a direct connection to the email and don't need to transmit it via any protocol.

      It should work. There are times when Gmail will interfere, though. I would test sending between two different accounts. (And give it time... there are spam fighting techniques that can introduce delays.)

    That is incorrect, there is an unofficial POP4, see Wikipedia.
