In this tutorial we are going to show you how to configure your Outlook email client with an existing mail account using the IMAP incoming mail protocol. IMAP keeps your emails stored on the server and syncs messages across multiple devices. It’s perfect for users who need access to their mailbox from various locations or devices. To learn more about the protocol, head to this article where we discuss it in detail.
You can add accounts from many dedicated email providers (Gmail, Yahoo, etc.) to an Outlook application. For the purposes of this tutorial, however, we will assume you are adding the custom email address you can create with our email service. We will also be using the latest version of the Outlook client.
This post includes:
Let's begin by adding a new email account in Outlook client. The first step is to open the application and look in the top-right corner. Click on the gear icon to open the settings.
The only thing we are interested here, for this tutorial, is the Accounts section. Click Add account. That will open a new pop-up where you can begin the process.
Type in the email address you want to add to the Outlook appliaction and then click Continue. That will take you to the configuration window where you can choose your protocol and then enter all the necessary details.
After you clicked Continue you will be prompted to enter your password. However, skip that step for now and instead click on Select Provider. That will show you a list of available providers (Microsoft, Gmail, Yahoo, and iCloud). However, we are only interested in the IMAP option for this tutorial. That way you can add your custom email address.
Select IMAP and now you can enter the password for your email account. Ensure it is the correct one otherwise you will not be able to add it to the application. Afterwards click on Show More which will expand the full configuration options.
Time to fill in the server details! This is what you will need:
The hostname for the incoming mail server for our services can be mail.yourdomain.com (where the yourdomain.com is your actual domain name). However, we always recommend using the name of the server your account is on. You can easily find it by logging into your account on FastComet.com. From the homepage, click on View Details next to the hosting plan that has the email account. You can find the server name in the FTP Server box. You will also find this information in the welcome email you got when you purchased the hosting plan.
Those were the settings for incoming mail. All that is left is to repeat the process for outgoing mails. That is what the SMTP section is for. SMTP itself is an outbound email protocol, and you can read more about it here.
The best part is that the settings for SMTP will be the same as for IMAP. The only difference is the port. Here is what each field is for:
Once you all the fields are filled, you can click Continue. After a short processing period you should see a message informing you the account was successfully added to Outlook.
That is all it takes to connect an email account to an Outlook application. When you click Done you will be taken back to your inbox where you will be able to see all your messages populating. Sometimes it takes a few moments, depending on how many emails Outlook needs to add. You can view these emails from any device that has access to the account. Remember to log out of any device you do not want to have access to this email account.
