As a WordPress expert, one thing that makes me absolutely crazy, e -mail delivery problems.
This means that even well-set contact forms are failed and emails are reset for the password. The worst thing is that your well-thought-out newsletter emails can land in Spam folders.
This happened to me when I relied on the Standard Mail system from WordPress.
It is like trying to send important emails without sender address. As a result, most E -Mail providers do not trust WordPress’s standard -e mail system. In addition, it is difficult to reflect your company when e -mails do not reach customers.
I tried everything first.
I tried it with manual e -mail senders to send and change various e -mail hosting providers. Nothing worked consistently.
Then I discovered that Simple mail transfer protocol or SMTPCould help me improve my e -mail delivery.
After further research, I chose WP Mail SMTP as my solution.
It is easy to use, saves detailed e -mail protocols and reports. In this way you can pursue open prices, click rates and email errors.

As a result, I came to the conclusion that WP Mail SMTP is the perfect solution for the connection of professional e -mail services with WordPress.

As already mentioned, WordPress has an integrated email function, but is very easy. Most of the time it doesn’t work well, and unfortunately your e -mails are not delivered.
This is because WordPress sends e -mails via your web server. However, web servers are not created for the delivery of e -mails and lack the proper authentication.
And the last nail in the coffin lacks a good reputation of the senders. This means that most e -mail providers see these e -mails as suspicious.
For example, Mail Mail blocks you while Outlook sends her to the Junk folder. Apart from that, there is no way to follow whether e -mails are delivered.

SMTP uses professional e -mail servers that provide proper authentication. Below you will find further reasons how SMTPS solve delivery problems.

- SMTP services offer delivery tracking and superior spam protection.
- Password reset to users are reached immediately.

Before starting, make sure that you have your Outlook -E -Mail address and your password. You also need access to your WordPress admin dashboard.
I also recommend keeping your Outlook account and WordPress dashboard open in separate tabs in order to avoid frustration that you have to do it later.
Before this case, let the establishment of this Outlook -WordPress connection with WP Mail SMTP guide you step by step.
How to connect Outlook automatically and manually

For the tutorial we use the WP Mail SMTP Pro version Because it contains A One-click setup For Office 365/Outlook integration.

To ensure that you can set up Outlook automatically and manually, I will guide you through both processes.

Next, scroll the “General” tab and search for it Mailer Section. Here you can see several E -Mail service options such as Amazon Ses, Google, Mailjet, Zoho and more.
Then select the 365/Outlook list with the check box.

Then the SMTP plugin automatically fills out most technical settings for you. This stores you in front of it to remember server names and port numbers.

Next, scroll on the same page to the text bar “From E -Mail” Adriebelema. Enter your full e -mail address in Outlook/Live/Hotmail here.

Next, activate the “From E -Mail” field to ensure the maximum e -mail delivery and minimize conflicts with other plugins. As soon as you are finished, you can find that you cannot add “strength from the name”, as this is automatically deactivated.
This is because Outlook does not support this setting like many other e -mail providers. Instead, e -mails with the account name are used to set up the connection.

Once finished, Save settings.
Next, scroll at the end of the page and press the Register at Microsoft Button.

This redirects them to the Outlook registration side. Click on the popup screen Accept How to authorize the WP Mail SMTP app so that you connect with Microsoft Outlook.

This method gives you complete control over your e -mail settings. With the manual process you can use them Free version of WP Mail SMTP To connect Outlook to WordPress.
To generate the information required for this section, you must set up a web application in your Microsoft Azure account.
This process does not require coding and I will lead it through the next step. Keep this WP -Mail -SMTP settings open in a separate tab or a separate window because you will soon return to you.
Step 1: Configure a Microsoft Azure account
First, you need one Microsoft Azure account To get ahead with the Setup process. If you have to create a new account, you can register for a free Microsoft Azure account.

Although creating an account is free, you have to enter your credit card data if you register for a Microsoft account. This helps to prevent SPAM registrations.
Since you most likely already have a Microsoft -E -EIMAM account (via Hotmail, Live, Outlook, Microsoft 365 etc.), you can easily log in with your existing account registration information at Microsoft Azure.
I should also point out that the email you use for your Azure account must be a Microsoft-based email address with approval for sending emails.
As soon as you have created and checked your account, you must open the Azure portal if you are not automatically redirected.
Step 2: Create an application-ID
Enter “App registrations” in the search bar at the top of the page on the top of the page. Next you will see a dropdown menu with a list of services. Choose and select “App Registration”.

Then at the top of the upper end of the App registrations You have to select the “+ New Registration” option.

Note: If you see the error message “the possibility of creating applications outside of a directory”, this means that you have not yet registered for an Azure account. You have to register and check your Azure account to register an application.
In the app registration form you will find the details that you have to fill out:
- Name: This only applies to your personal organization. I therefore recommend naming you like “WP Mail SMTP: yourdomain.com”.
- Supported account types: Choose “Accounts in an organizational directory and personal Microsoft accounts”.

Next you have to add the diversion url of the page on your website, for which you are diverted with Microsoft after authentication.
To find the diversion -URI, switch back to the tab or the window where you have opened the WP -Mail -SMTP settings of your website. Then under the Outlook / 365 In section you will see a field called “forward to Uri”.

Copy this URL and then add it to your Microsoft Azure app registration form. When you’re done, click the “Register” button to continue.

As soon as this registration form is submitted, they will be redirected to the overview Page. Here you will find your application (client) -id. Go ahead and copy this value.

As soon as you have copied the application ID (client), you must insert this full value in your WP -Mail -SMTP settings in the “Application ID” field.
Step 3: Create an application pass
Next we have to generate a password for this app. To do that, go to Manage »Certificates and secrets In the left sidebar within the app that you have registered in Microsoft Azure.

On this screen, click on the “+ New Client Secret” option. Then fill out the “Add a client secret” form with the following details.
- Description: Add “
app_password
”Or something similar, you can easily remember this text bar. This name is intended for your use. I therefore recommend a logical and simple name. - Runs off: 730 days (24 months).

After you have submitted the client secret form, the application passport is generated. Copy the password from the “Value” column and then return to your WP mail -SMTP settings.

You will not be able to access them Value After you have finished this page, I therefore recommend saving the value in a safe place if you have to access it again.
As soon as you have returned to the tab or the window in which your settings are still open, insert this value into the “Application Password” field. You should find this field right below, where you have inserted “Application ID”.

As soon as you have added your application ID and your application passenger, click the “Save settings” button below.
After you have saved the settings, you have to scroll down to the authorization section. You should now allow a button with the name “Plugin to allow e -mails with your Microsoft account.” Keep on and press this button.

As soon as you have clicked the button, you should be redirected to a Microsoft registration page as with the one-click setup process.
That’s it! You can now connect Outlook to WordPress both manually and automatically with WP Mail SMTP.
Test your e -mail connection
Now comes the exciting part. You can see if everything works. I always recommend testing your SMTP setup because even a small error can cause considerable errors.
How do you test your SMTP connection?
First go to WP in your WordPress dashboard Mail -SMTP »Tools And go to the “E -Mail test” tab.
Then enter your e -mail address in the “Send” field and click on the Send e -mail Button.

Check your e -mail mailing input after completing. Your test -E email should arrive in one moment and look something like this:

When the e -mail arrives, congratulations! Your setup works perfectly. In addition, the e -mail should display your Outlook name and your e -mail as the sender.
If the test -e mail is not arriving, panic. I will show you how you can fix the most common problems in the next step.
Troubleshooting with common problems
Even with perfect setup instructions, things sometimes don’t work on the first attempt. I helped hundreds of people to fix the same problems. In addition, the solutions are usually easy if you know what you have to look for.
The most common problem is authentication failure. This occurs if WordPress cannot register in her Outlook account.
You will see an error message such as “Authentication failed” or “invalid login information”, apart from your test -e emails that are not sent.
- First, Check if you have entered your email address correctly. A false letter also causes problems.
- Another common problem is Port block. Some web hosting companies block the E -Mail ports that Outlook uses.
- If your test has an e -mail -e -e -mail time or is not connected, contact your hosting support. Ask them too Imperial connection 587 for SMTP connections.
- I have also seen problems with “E -Mail addresses. Your “from e -mail” must match Your Outlook -E email address.
- You Another e -mail address cannot be used Here, even if it is another e -mail you own. Also ensure that there are no additional spaces before or after the E -Mail address.
- When e -mails reach their inbox, but go to spam. Check your domain call. New domains are sometimes characterized as suspicious.
- Also make sure your website has Correct SPF and DKIM recordings Set up via your domain provider.
- Sometimes the plugin shows errors “connecting times”. This usually means yours The hosting provider has strict firewall rules.
Apart from that, it could be that your server has temporary connection problems. Wait 10 minutes and try again.
These options should help you fix your SMTP connection quickly and to get you up to running without expert aid.

I use Mail Mail for personal projects and small customers. It is reliable and free of charge for basic use. In addition, the Google servers have an excellent reputation for other e -mail providers.
