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

Sending an email to the same set of people repeatedly — your team, your book club, your department — gets tedious fast. Outlook solves this with Contact Groups (previously called Distribution Lists), which let you email a defined group of people using a single name. Here's exactly how it works, what versions handle it differently, and the variables that affect your experience.

What Is an Email Group in Outlook?

An email group in Outlook is a saved collection of email addresses stored under one name. When you type that name in the To, CC, or BCC field, Outlook automatically expands it into all the individual addresses in the group. You manage the list in one place — add someone, remove someone — and every email you send using that group name reflects the update instantly.

This is different from a Microsoft 365 Group or a shared mailbox, which are admin-provisioned features with their own inboxes, shared calendars, and collaborative tools. A Contact Group is personal — it lives in your own contacts and is only visible to you unless you share it.

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

The classic Outlook desktop app (Windows) is where most people do this. The steps are consistent across Outlook 2016, 2019, 2021, and Microsoft 365:

  1. Open Outlook and go to the People section (the contacts icon in the bottom-left navigation).
  2. Click New Contact Group in the Home ribbon.
  3. Give the group a clear, recognizable name in the Name field.
  4. Click Add Members, then choose from:
    • From Outlook Contacts — people already in your contacts list
    • From Address Book — your organization's directory (if applicable)
    • New Email Contact — manually enter an address not yet saved
  5. Add all the members you need, then click OK.
  6. Click Save & Close.

Your group now appears in your contacts and is searchable from any compose window. 📋

How to Create a Contact Group in Outlook on Mac

The Mac version of Outlook follows a slightly different path:

  1. Open Outlook and click People in the sidebar or bottom navigation.
  2. Click New Contact List (the terminology differs slightly from Windows).
  3. Name the list and begin typing names or email addresses into the members field.
  4. Outlook will suggest matches from your existing contacts or directory.
  5. Save the list when complete.

If you're using the New Outlook for Mac (the redesigned version Microsoft has been rolling out), the interface is closer to Outlook on the web, so the steps may align more with the web version below.

How to Create a Contact Group in Outlook on the Web (OWA)

Outlook on the web — accessed through outlook.com or your organization's Microsoft 365 portal — handles groups through the People section:

  1. Go to People (via the app launcher or the people icon in the left nav).
  2. Click New contact list (you may see a dropdown arrow next to "New contact").
  3. Name your list and add members by typing names or addresses.
  4. Click Create.

Contact lists created in Outlook on the web sync with your Microsoft 365 account, so they'll also appear in the desktop app if you're signed in with the same account — as long as the contact list is stored in your Exchange or Microsoft 365 mailbox (not a local PST file).

Using Your Contact Group When Sending Email

Once created, using the group is simple:

  1. Start a new email.
  2. In the To, CC, or BCC field, start typing the group name.
  3. Outlook will suggest it as an autocomplete option.
  4. Select it — Outlook expands it to show all member addresses, or keeps it collapsed as a group name depending on your settings.

You can expand the group manually by clicking the + icon next to the group name in the recipient field, which lets you remove individual members from that specific send without editing the group itself. 📬

Key Variables That Affect How This Works

VariableWhat Changes
Outlook versionDesktop vs. web vs. Mac have different UI paths and feature labels
Account typeExchange/Microsoft 365 accounts sync groups across devices; POP/IMAP/local PST accounts don't
Organization IT policySome organizations restrict creating personal contact groups or enforce distribution lists through the Global Address List instead
New vs. Classic Outlook toggleMicrosoft is actively rolling out a redesigned Outlook; if you've switched to "New Outlook," the interface closely mirrors the web version
Contact storage locationGroups saved to a local PST won't sync; groups saved to your Exchange mailbox will

Managing and Editing a Contact Group

To edit an existing group, go back to People, find the group, and double-click to open it. From there you can add members, remove members, or rename the group entirely. Changes take effect immediately for future emails.

If you delete a member from Outlook Contacts entirely, they aren't automatically removed from Contact Groups that include them — you'll need to update those groups manually.

When Contact Groups Aren't the Right Tool

Contact Groups are personal and one-directional — you send to them, but there's no shared inbox, no reply-all threading tied to the group, and no collaborative features. If your team needs a shared email address, a place for threaded conversations, or a way for multiple people to manage incoming messages together, a Microsoft 365 Group or a proper distribution list set up by an IT admin would serve a different purpose.

The right choice between a personal Contact Group and an organizationally managed distribution list depends on your role, whether you're in a managed Microsoft 365 environment, and how many people need to send from — not just to — that group. 🔧

Whether a simple Contact Group covers your needs or whether your workflow calls for something more structured is a question your specific setup and communication patterns will ultimately answer.
