Is Outlook email free for business?

Microsoft Outlook offers a free plan, but it doesn’t come with a custom domain (only an @outlook.com one), which may not be suitable for business use. It also only accommodates one user. Microsoft 365’s business plans start at $6 a month and let you use a custom email domain (e.g., [email protected]) and add multiple users to your organization. It also comes with the Microsoft Office productivity suite, including Word, Excel, and PowerPoint.

Should I use Outlook or Gmail for business email?

Use Outlook for your business email if you need a lot of email and cloud storage. Microsoft provides up to 50GB of mail storage and 1TB of cloud storage on all its Business plans. It’s also a good option for more productivity tools like a collaborative workspace or online video editor. Choose Gmail if you want an easier setup process and beginner-friendly interface or are more familiar with the Google Workspace productivity suite.

How to Create a Business Email With Outlook in 5 Easy Steps
February 19, 2025 - To create an Outlook business email, you’ll need a custom email domain, aka what comes after the “@” symbol in your email (like “@fitsmallbusiness.com” instead of “@outlook.com”). You can get that by upgrading to a Microsoft 365 Business plan, which also comes with Microsoft’s productivity tools, including Microsoft Word and Excel and its cohorts.

Hello Next Service,

Good day!

Thank you for posting to Microsoft Community. We are happy to help you.

Setting up a business email with Microsoft 365 can seem overwhelming at first, but I'm here to guide you through the process. Let's break it down into a few steps:

  1. Purchase a Microsoft 365 Subscription: If you haven't already, you'll need to sign up for a Microsoft 365 subscription. You can choose the appropriate plan based on your business needs, which includes email services along with other productivity tools. Purchase or trial an Office 365 for Business subscription via https://products.office.com/en-us/business/compare-more-office-365-for-business-plans, and some of the subscriptions.

Example: sign up for the ‘Microsoft 365 Business Premium’ subscription and follow all the steps.

  1. Choose a Domain Name: Next, you'll need to decide on a domain name for your business email. Ideally, it should reflect your company or brand name. If you already own a domain, you can use that. Otherwise, Microsoft offers domain registration services, or you can purchase one from a domain registrar.
  2. Configure DNS Settings: Once you have a domain name, you'll need to configure the DNS (Domain Name System) settings to point to Microsoft 365. This involves adding some specific DNS records, such as MX (Mail Exchanger) records, to your domain's DNS management panel. This step is crucial for routing your business emails correctly.

Reference: Add a domain to Microsoft 365 - Microsoft 365 admin | Microsoft Learn

  1. Create User Accounts: After configuring the DNS settings, you can start creating user accounts for your business. These accounts will have email addresses associated with your domain (e.g., ******@yourbusiness.com). Use the Microsoft 365 admin center or the Exchange Admin Center to add and manage user accounts.
  2. Set Up Email Clients: To access your business email, you have different options. You can use the web-based Outlook app (Outlook Web App) or configure third-party email clients like Microsoft Outlook, Apple Mail, or Thunderbird with your Microsoft 365 account. Each email client may have specific configuration steps, so it's best to follow the instructions provided by Microsoft or the client you're using.

Reference: Add an email account to Outlook - Microsoft Support

  1. Configure Email Security: It's crucial to configure proper security measures for your business email, such as enabling multi-factor authentication (MFA), setting up spam filters, and implementing email encryption if necessary. These measures help protect your account and ensure the confidentiality of your communications.

Remember, can assist you with any specific questions or issues you may encounter along the way. Please feel free to let us know if there are any questions or if we've got you wrong. We will keep assisting you based on the information you provide. We sincerely appreciate your patience and cooperation.

Dear Edmund Comber,

Good day! Thank you for posting to Microsoft Community.

I do apologize for the deleted thread, but you created a duplicate thread, and for the first thread you created our moderator provide possible answers for the query, you can refer to: How do I use my Non Microsoft email account (******@mycompany.com) as - Microsoft Community. So, since the second thread was a duplicate, our moderators deleted it to avoid confusion for other users in the community.

However, to answer your questions, when you register for Microsoft 365 business standard, you should enter your domain, then based on that domain Microsoft provide email address. Let's say you have a domain called mycompany, so Microsoft provides ******@mycompany.onmicrosoft.com email address as an initial email account. Once you completed the registration and sign in to Microsoft 365 admin center, you can add or verify your domain (mycompany.com), then you can create your email address you want to have and assign license. To do this kindly refer to the following articles.

  • Set up Microsoft 365 Business Standard with a new or existing domain - Microsoft 365 admin | Microsoft Learn
  • Add a custom domain name - Microsoft Support
  • Add users and assign licenses in Microsoft 365 - Microsoft 365 admin | Microsoft Learn

I look forward to your update. Please feel free to let me know how it goes or if I got you wrong. If you still have any concerns, please let me know so I can provide more suggestions. 

Thank you for your precious time. Have a nice day.Sincerely,Libeamlak | Microsoft Community Moderator

Hi Libeamlak,

Thank you so much, I was not aware that I had made a dual post and this was nor stated in the message I got about the post being deleted.

The answer I got from the original post that you directed me to was extremely helpful, and I would not have known it was there without your response, so thank you very much indeed.

The links you posted to me are absolutely spot on, so thank you once again.

@BAMA IT ,
It sounds like you are trying to create Microsoft accounts using your company's email addresses, but the system is rejecting them. There are a few potential reasons why this might be happening:

  • Microsoft may not allow you to use a business email address to create a personal Microsoft account. In this case, you need to use a different email address (such as a personal email address) to create the Microsoft account.
  • Your company may have policies that prevent you from using business email addresses to create personal accounts. In this case, you would need to check with your company's IT department or email administrator to see if there is a way to create Microsoft accounts using your company's email addresses.
  • There could be a technical issue preventing you from creating the Microsoft accounts. In this case, you may want to try again later or contact Microsoft support for assistance.

If you want to use your company's email addresses to log into Microsoft services, the best way to do this would be to use Azure Active Directory (AAD) to manage the accounts. With AAD, you can create and manage user accounts for your company and use these accounts to log into Microsoft services such as Office 365, Microsoft Teams, and others. This will allow you to use your company's email addresses to log into these services while still maintaining control over the accounts and ensuring that they are only used for business purposes.

Can I use personal email address also with a business account? - Microsoft Q&A
You can switch to a business account and add your personal email address as an alias or secondary email address. Correct me if I am wrong, if you want to use your personal account and business account with same user ID, that's Not possible, because of the domain name. As you know, your personal account comes with the domain of outlook or Hotmail. but if you subscribe to a business account, you will get a onmicrosoft.com domain. You can of course use your custom domain too. You can only use your personal account to create a business account, but you cannot login with the same user ID (personal) to login into business account.
