Note: One thing you must be aware of is that your outlook SMTP server has a total of 300 emails per day or 100 recipients per day limitation.

Outlook POP Settings

While with outlook SMTP settings you can send emails to anyone via your outlook account, outlook, as well as IMAP settings, will let you retrieve or import incoming emails. We will cover outlook IMAP settings in the next section.

In order to receive emails from Outlook in your email client, you will be required to do either POP3 or IMAP settings in your email client. But to be honest, IMAP is way better to use than POP3, it is because IMAP lets you do two-way syncing due to which it becomes possible to access email from multiple devices such as desktop PC or smartphones.

But, if you are going to use only a single device, POP3 would be better.

One thing, you must also note that by default the POP3 will be disabled in Outlook and you have to enable it manually.

To do so, open your Outlook App and click on the gear icon located at the top right corner as shown in the picture below:

Enabling Outlook POP settings

Now search “POP” in the search box, and you will get a list of the search results in which you have to click on “POP and IMAP“. A separate window will pop- up in which you have to select the “Yes” option under the pop option as shown in the picture below:

After that, you will have an option to choose whether or not to let apps or devices delete messages from Outlook. And after everything is done click on the Save button.

Now, after successfully enabling the POP3 access, you can use the POP settings as follows:

  • POP server:
  • Port: 995
  • Encryption method: TLS

Let us see what the outlook IMAP settings are:

As we have already mentioned in the above section, IMAP has an edge over POP in terms of syncing messages with multiple devices. Therefore, even outlook enables it in their system by default. So, the only thing you need to do is to use the following Outlook IMAP settings.

  • Encryption method: TLS
