Microsoft Outlook allows users to easily organize their email accounts, contacts, and messages conveniently in one place. It is particularly helpful for professionals or business owners who want a centralized management area for their mailbox.
However, setting up Outlook can be tricky if you are using a custom email since you need to add various details to link the server. There are also different Outlook versions, each with a separate configuration process.
In this article, we will explain how to set up Outlook with Hostinger’s email hosting plan using different Outlook versions, including mobile.

Before setting up Outlook, you need to complete a few steps to ensure a smooth configuration process.
For Outlook, we recommend creating a professional email address with a custom domain, like yourname@businessname.com. Compared to free addresses from Google or Webmail, it offers several benefits for your business.
For instance, the custom domain makes your email appear more credible and legitimate. Such a mailbox is also better protected since the provider hosts it on a private server and typically adds extra safety features.
For example, the Hostinger business email hosting plan, starting at 0/month, has built-in antivirus software and advanced anti-spam protection. Our email service also supports IMAP and POP, which Outlook needs to establish a connection with the mailing server.
In addition to an email hosting plan, you need a domain name from a registrar. If you choose the Hostinger Business Premium plan, you don’t need to worry about that as you’ll get a domain name for free. Otherwise, we recommend buying a domain name from Hostinger to simplify the setup process since you can manage all services from hPanel.
If you use Hostinger’s web hosting plan, you will get a free email and a custom domain. This means you don’t need to buy additional services before setting up Outlook.

Pointing your domain ensures your email uses the correct server, enabling your mailbox to receive and send messages. At Hostinger, your domain should point to the right address by default. To check or change it, follow these steps:


Now, let’s change the MX records. These are DNS settings that specify your email address server destination. To do so, navigate to the same DNS/Nameservers menu of your email domain.
From the DNS record list, check if you already have two MX settings with the following values:
If the MX records’ values are incorrect, click Edit and enter the new setting. Click Update to save the changes.
Meanwhile, if you can’t find existing MX records, navigate to the Manage DNS records section. Enter your MX record settings in the respective fields and click Add Record. Remember to do so twice since you need two records.
To configure Outlook, we must add the email address IMAP, POP, and SMPT settings to the client. Here’s how to find the details on Hostinger email:


Now that you have all the required details let’s set up your email in Outlook. Skip to the respective section if you are configuring the client on a particular device.
Here are the steps to configure Microsoft Outlook 2019 using a Hostinger professional email account:


If you encounter an error, click Change Account Settings and check if all the details are listed correctly.
The general procedure to set up Hostinger email on Outlook 2016 is similar to the 2019 version, but there are additional steps. Here’s how to do so:



If you encounter an error, ensure you choose None as the SMTP encryption method and verify other settings.
Important! Microsoft will end the extended support for Outlook 2016 on October 14, 2025. If you are still using this version, we recommend upgrading immediately to avoid potential security risks.
The steps for setting up the Outlook app for iOS are similar to those of the desktop version but with a different user interface. After downloading the application from the app store, open it and follow these steps:
In this section, you will learn how to set up Outlook using a Hostinger business account on an Android device. Once you downloaded the application from the Google Play Store, open it and do the following:
If you are using Outlook on multiple devices, you can easily connect your email address via hPanel. You won’t need to add the IMAP or POP3 details whenever you set up a new app in another system. Here’s how to do so:

Wait until the new DNS propagates worldwide, which usually takes up to 24 hours. You can check the progress using a DNS Checker to see if the CNAME records point to the correct addresses.
Once finished, open any Outlook application and add a new account. Enter your business email address and password.
That’s it! The mail client might take up to 10 minutes to link with your Hostinger mailbox.
To set up an Outlook inbox for a Hostinger email address automatically, you will need an email address, proper MX records set up, and your domain pointed to Hostinger servers.
Internet Message Access Protocol (IMAP) and Post Office Protocol (POP) are two methods for accessing email messages from the server. While you can use either to connect Outlook, there are important distinctions that make them suitable for different use cases.
IMAP
IMAP stores the messages in the application server instead of locally in the device storage. It lets you access your email mailbox anywhere, using different devices, so long as there is an internet connection.
While flexible, this protocol is slower than POP since you must manually open the email client to download the message and attachments.
POP
POP downloads messages and attachments automatically from the mailing service without the user having to open them manually. Then, it stores the data locally on your device, enabling offline access.
However, you can’t access the email from another system. It makes POP suitable if you often work offline and use a single computer or mobile device.
Outlook has an auto-reply feature that lets you respond to messages when you are out of the office or offline. To set it up, open Outlook and go to File → Automatic Replies.
Select Send automatic replies, enter your message, and click OK to confirm. Optionally, you can enable this feature during a specific time and write a different message for people outside your organization.
Outlook helps you efficiently organize your business mailboxes and contacts using a single client. Before setting it up, ensure you have an email hosting plan from a provider like Hostinger and acquire the IMAP or POP details.
The general procedure to set up the client is similar regardless if you use Outlook 2019, Outlook 2016, iOS, or Android.
Here is a summary of the steps:
IMAP is suitable for multi-device users since Outlook stores your messages within the client’s server. Meanwhile, POP downloads your emails to your device, enabling offline access but limited to a single computer.
