How to Create a Distribution List in Outlook

If you regularly email the same group of people, like your team, a project squad, a client list, or a board of investors, typing every address each time is a waste of clicks. A distribution list in Outlook lets you bundle those contacts under one name and email them all at once. Here's how to create, edit, share, and manage one, plus where it differs from a Group or a shared mailbox.

What is a distribution list in Outlook?

A distribution list in Outlook (also called a Contact Group in modern Outlook) is a saved set of email addresses you can email under one name. Instead of typing "anna@, bob@, carla@..." every time, you type "Marketing Team" and Outlook expands the list automatically.

Members can be inside your organization, external, or a mix. Distribution lists are in your personal contacts by default, which means only you can see and use them, unless you share the list (covered further down).

Distribution list vs Group vs Shared Mailbox in Outlook

The terms get mixed up constantly. The short version:

• Distribution list (Contact Group): a personal, saved set of email addresses. You email them under one name. They can't reply to each other from the list, and the list doesn't have its own inbox.
• Microsoft 365 Group: a shared workspace with its own inbox, calendar, and OneDrive folder. Members can converse, share files, and access common tools.
• Shared mailbox: a single inbox multiple people can read and send from, e.g., a "support@" or "sales@" address. Different from a distribution list because it has its own mailbox.

If you want to email a fixed group of people, a distribution list is the right tool. If the group also needs a shared inbox or files, use a Microsoft 365 Group or shared mailbox instead.

How to create a distribution list in Outlook

To create a distribution list in Outlook (new Outlook or Outlook 365), open the People view from the left sidebar. Click New contact, then choose Contact list (or New contact list, depending on your version). Give the list a name, type or paste in the email addresses you want to include, and click Create.

Set up a list → People → New contact list → name it, add addresses, Create.

In classic Outlook (the desktop app), the steps are similar but with slightly different labels:

Home tab → New Items → More Items → Contact Group.

Name the group, click Add Members → From Address Book (or From Outlook Contacts), select the people, and Save & Close.

Tip: Outlook lets you add up to 1,000 members per distribution list, but anything over 100 starts behaving like a mailing list and may trigger spam filters when you send. For larger lists, use a Microsoft 365 Group.

If you've ever wondered how to make a distribution list in Outlook, the steps above are the answer; "make" and "create" mean the same thing here.

How to edit a distribution list in Outlook

To edit a distribution list in Outlook, open the People view, find the list, and double-click it. From there you can add new members, remove people who have left the team, or update outdated email addresses. Save when you're done.

Common mistake: edits to the list only sync to other devices if you're using Outlook with a Microsoft 365 account. If you're on a local POP3 or IMAP setup, the list lives only on the device where you created it.

How to share a distribution list in Outlook

To share a distribution list in Outlook, open the list, then click Forward Contact in the ribbon (under the Contact tab). Choose "As an Outlook Contact," address the email to the colleague who needs the list, and send. They open the attachment, click Save & Close, and the list appears in their own contacts.

If both you and the recipient are on Microsoft 365, you can also share lists by converting them into a Microsoft 365 Group, which gives everyone permanent access without each person needing to import their own copy.

Distribution list shortcuts and tips

• Type just the list name in the To field and Outlook expands it to every address.
• To preview members before sending, click the "+" icon next to the list name when it appears in the To field.
• BCC distribution lists for external sends if you don't want recipients seeing each other's addresses.
• Lists created in a personal Outlook profile won't sync to Outlook for Web automatically; you'll need to re-create them in the web version if you use both.

Key takeaways

A distribution list in Outlook is a saved set of email addresses you can email under one name. Create it from People → New contact list (modern Outlook) or Contact Group (classic Outlook), add members, save. To edit, open the list and add or remove people. To share, use Forward Contact → As an Outlook Contact. For groups that need a shared inbox or files, use a Microsoft 365 Group instead.
