How to Create an Outlook Email Group (Contact Group / Distribution List)

Sending the same email to a recurring set of people — your team, a project committee, a family thread — gets tedious fast when you're adding addresses one by one. Outlook solves this with Contact Groups (called Distribution Lists in older versions), which let you address a single name and reach everyone at once. Here's exactly how to set one up, across the platforms where Outlook runs.

What Is an Outlook Email Group?

A Contact Group in Outlook is a saved collection of email addresses stored under one label. When you type that label in the To field, Outlook expands it automatically to include every member. It lives in your personal contacts, which means:

• It's only visible to you unless shared separately
• It works for any recipient — colleagues, external contacts, or personal connections
• It does not require an admin or an Exchange server to create

This is different from a Microsoft 365 Group or a shared mailbox, which are organization-wide resources managed by IT. If you're looking for a personal shortcut to send to a fixed list, a Contact Group is what you want.

How to Create a Contact Group in Outlook for Windows (Desktop App)

This applies to Outlook versions included with Microsoft 365, Outlook 2021, 2019, and 2016.

1. Open Outlook and go to the People icon (bottom-left navigation bar — it looks like a silhouette)
2. In the ribbon at the top, click New Contact Group
3. Give your group a clear, recognizable Name (e.g., "Marketing Team" or "Book Club")
4. Click Add Members, then choose from:
   • From Outlook Contacts — people already in your address book
   • From Address Book — your organization's global directory
   • New Email Contact — add someone not yet saved
5. Select or enter each member, clicking Members → to add them to the list
6. Click OK, then Save & Close

Your group now appears in your contacts and is available immediately when composing email. 📋

How to Create a Contact Group in Outlook on Mac

The Mac version of Outlook (Microsoft 365 subscription) handles this slightly differently:

1. Click the People tab in the left sidebar
2. Select New Contact List from the toolbar
3. Name the list
4. Start typing names or email addresses in the Add members field — Outlook will suggest matches from your contacts and directory
5. Press Return after each entry to confirm
6. Click Save

Note: On Mac, these are called Contact Lists, not Contact Groups — same function, different label.

How to Create an Email Group in Outlook on the Web (OWA)

If you use Outlook through a browser (outlook.office.com or outlook.live.com):

1. Click the People icon in the left-side app launcher
2. Click New contact → New contact list
3. Enter a List name
4. Add members by typing names or email addresses
5. Click Create

The group syncs across devices tied to the same Microsoft account, so it's accessible from desktop Outlook and mobile as well. 🌐

How to Use Your Contact Group When Sending Email

Once created, using the group is straightforward:

1. Open a new email and click in the To field
2. Start typing the group name
3. Select it from the autocomplete suggestions
4. Outlook expands all addresses behind the scenes — recipients won't see a "group" label, just the individual addresses (or a collapsed group, depending on settings)

You can also add the group to CC or BCC the same way.

Key Variables That Affect Your Setup

Not every Outlook environment behaves identically. A few factors shape the experience:

Personal vs. Work Accounts

If you're using Outlook connected to a corporate Microsoft 365 account, your organization may already have distribution lists managed by IT — these appear in the address book and cover whole departments. Personal Contact Groups you create sit separately, in your own contacts folder.

If you're on a personal Outlook.com account, Contact Lists work the same way but sync through Microsoft's consumer infrastructure rather than a business Exchange server.

Editing or Deleting a Contact Group

Groups aren't frozen once created. To modify one:

• Add members: Open the group from People, click Add Members
• Remove members: Select the name in the list, click Remove Member
• Rename: Double-click the group and edit the name field
• Delete: Right-click the group in your contacts and select Delete

Changes take effect immediately for future emails — they don't affect messages already sent.

When a Contact Group Isn't the Right Tool

Contact Groups work well for stable, personal lists. But depending on your situation, other tools may serve better:

• Microsoft 365 Groups — for teams that need shared inboxes, calendars, and file storage
• SharePoint or Teams channels — for ongoing collaboration, not just email
• Mailing list services — for newsletters or large external audiences where tracking and unsubscribes matter

Whether a simple Contact Group covers your needs — or whether you'd benefit from a more structured solution — depends on how many people you're reaching, how often the list changes, and whether this is a personal workflow or part of a wider team setup.
