Setting SMTP settings in Outlook can be tedious. If you do not set them correctly, your emails will not get sent and you will have a lot of frustrated customers. In this blog post, we are going to walk through the SMTP settings for Outlook 2022 so that you can make sure your email gets delivered every time!

Is it possible to find the appropriate Outlook SMTP settings?

You may use your Outlook account to send emails with an Outlook SMTP server. Alternatively, if you have a WordPress website, you may also configure WordPress to send its emails using your Outlook account to increase the site’s email delivery.

In this post, we’ll go through all of the Outlook SMTP settings you need to know about. We’ll begin by describing the actual SMTP settings, as well as the POP3 and IMAP configurations (to receive emails in addition to sending). We’ll also show how to set up WordPress to send emails using Microsoft Outlook.

Settings for Outlook SMTP

Here are all the details you’ll need to configure your email client or WordPress website to connect with the Outlook SMTP server:

  • SMTP Server:
  • Port: 587
  • Requires SSL: Yes
  • Requires TLS: Yes (if available)
  • Authentication: Yes (If different login choices are available, choose Login.)
  • Username: Your Outlook email address (e.g.
  • Password: Your Outlook password — Use your account to log in to the Exchange Server website.

Outlook’s SMTP server has certain sending restrictions that you should be aware of: you can send up to 300 emails a day to 100 recipients.

POP3 Settings for Outlook Express

While OutlookSMTP allows you to send emails using your Outlook account, POP3 and IMAP allow you to import messages that others have sent you. The next section will deal with IMAP in detail.

If you want to read your Outlook emails on another computer, make sure you add the POP3 or IMAP credentials to access them in your email program. If you want to access emails from several devices (such as a desktop and smartphone), IMAP is preferable than POP3. nPOPn, on the other hand, can be a superior

To change your settings, click on the gear symbol in the upper-right corner of the Outlook window and choose “settings.” Then search for “pop” under Settings. Select POP & IMAP from the drop-down menu (or go to this link to jump right there). nYou should be aware that by default, Outlook disables POP3

Select Yes under the Let devices and apps use POP option in the POP options area. You may then choose whether or not to allow applications and gadgets to delete emails from Outlook or keep them permanently.

  • Encryption method: TLS

Outlook IMAP Settings

As we said before, if you want to access your emails from several devices, IMAP is usually the way to go. Outlook has IMAP enabled by default, so all you have to do now is enter these settings:

  • Server:
  • Port: 993
  • Encryption method: TLS

How to Use Outlook SMTP to Send Emails to WordPress Sites

If you wish to increase the reliability of your WordPress site’s emails, consider using Outlook SMTP servers with a large message size (from 300 to 100 recipients) when sending.

The setting process is fairly simple, as it only entails importing the Outlook SMTP server settings into a WordPress SMTP plugin (see below). If you run into difficulties, you may also try out other free SMTP servers, such as Gmail’s free SMTP server.

1. Set the “From” Details for the mail server by enabling and configuring the SMTP plugin.

A WordPress SMTP plugin is required to use an SMTP service with WordPress. There are several popular choices, but the Post SMTP plugin is our favorite since it’s completely free and offers features that will help you troubleshoot any problems you may have with your site’s email operation.

Install and activate the free plugin on to get started. Then, in your WordPress dashboard’s New Post SMTP area, choose to Display All Settings:

Enabling POP access for Outlook

Then, go to the Message tab and fill in your “From” email address and name. Use Outlook’s account email, but anything you want your recipients to see is fine, like so:

When you’re finished, remember to save your changes.

2. To enable the Outlook SMTP Server plugins, go to its Settings.

Then, to reload the full settings, go back to the Show All Settings option.

In the Account page, select SMTP from the Type dropdown and make sure the Mailer Type dropdown shows PostSMTP.

You should now see an extended set of choices in the area below the Outlook SMTP server details field. Follow these instructions:

  • Outgoing Mail Server Hostname:
  • Outgoing Mail Server Port: 587
  • Simply insert your Outlook email address. You may experience problems if you use a different email address.
  • Security: STARTTLS
  • Authentication: Login
  • Username: Your full Outlook email address.
  • Password: Your Outlook password — the same one you use to log in to the Outlook website.

3. Create a test email and send it

You’ve finished configuring your WordPress site to connect to the Outlook SMTP server to send emails.

The plugin includes a capability to send a test email in order to verify that everything is in good working order.

To do this, go to the Post SMTP area and select Send a Test Email from the drop-down menu:

You should use a different, free SMTP server if you can’t figure out what’s wrong. You might consider using another free SMTP server, such as Gmail’s free service.


You may use your Outlook account to send emails by setting up the Outlook SMTP server.

The advantage for WordPress users is that it increases the dependability of your site’s emails since you’re utilizing Outlook’s optimized SMTP servers. Furthermore, most WordPress sites should be able to send 300 emails per day without issue.

The SMTP server enables you to use your client’s interface to send emails. You’ll be able to read your Outlook emails in the email software or client of your choice if you connect it with POP3 or IMAP.
