How to Create a New Group in Outlook (And When Each Method Makes Sense)

Outlook offers more than one way to group contacts or collaborators — and the method that works best depends heavily on which version of Outlook you're using, what you're trying to accomplish, and how your email account is set up. Understanding the difference before you start saves a lot of frustration.

What "Groups" Actually Means in Outlook 📋

Outlook uses the word "group" in two distinct contexts, and mixing them up is one of the most common sources of confusion:

Contact Groups (formerly Distribution Lists): A private list of email addresses you create and store in your personal contacts. When you email the group name, it sends to everyone on the list. Only you can see and use it.

Microsoft 365 Groups (Outlook Groups): A shared workspace connected to a Microsoft 365 account. Members get a shared inbox, calendar, file storage, and sometimes a Teams channel. These are visible to others and managed at the organizational level.

Knowing which one you need determines which steps to follow.

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

This method works in Outlook for Windows and Outlook for Mac with a standard Microsoft account or Exchange/Microsoft 365 account.

On Windows:

1. Open Outlook and go to the People section (the contacts icon in the bottom-left navigation bar)
2. Click New Contact Group in the ribbon
3. Give the group a name in the Name field
4. Click Add Members — you can add from your Outlook contacts, address book, or by typing email addresses manually
5. Click Save & Close

Your new contact group now appears in your contacts list. To use it, simply type the group name in the To field of a new email.

On Mac:

1. Open Outlook and select People from the left sidebar
2. Click the + button and choose New Contact List
3. Name the list and add members by typing names or email addresses
4. Save the list

Note: Mac uses the term Contact List rather than Contact Group, but the function is identical.

How to Create a Microsoft 365 Group in Outlook

This option is only available if your account is connected to a Microsoft 365 subscription (typically through a work or school account). It won't appear for personal Outlook.com accounts.

In Outlook for Windows:

1. In the left-hand navigation pane, find Groups (below your mail folders)
2. Right-click Groups and select New Group, or click the + icon next to "Groups"
3. Enter a group name — Outlook will suggest an email address automatically
4. Set the privacy level: Private (invite only) or Public (anyone in your org can join)
5. Add members by name or email
6. Click Create

The new group gets its own shared inbox, calendar, and file library accessible by all members.

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

For users accessing Outlook through a browser at outlook.office.com or outlook.com:

1. In the left sidebar, scroll down to find Groups
2. Click New group
3. Fill in the group name, description, and email address
4. Choose the privacy setting
5. Add members and click Create

If you don't see a Groups option in the sidebar, your account either doesn't support Microsoft 365 Groups, or the feature has been disabled by your organization's IT administrator.

How to Create a Contact Group in Outlook Mobile

The Outlook mobile app (iOS and Android) has limited group management features. You can view and email existing contact groups, but creating new ones directly in the app isn't supported in most versions. For full group creation, you'll need the desktop app or web version.

Key Variables That Affect Your Setup 🔧

Contact Group vs. Microsoft 365 Group: A Quick Comparison

Editing and Managing Groups After Creation

Once a group exists, you can update it without starting over:

• Add or remove members by opening the group from your People or Groups section and editing the member list
• Rename the group through the group settings or properties panel
• Delete a Contact Group by right-clicking it in your contacts and selecting Delete
• Delete a Microsoft 365 Group requires group owner permissions; deleted groups can sometimes be recovered by an admin within 30 days

Where the Variables Come In 🔍

The mechanics described above are consistent across standard installations, but real-world outcomes vary. A user on a corporate Microsoft 365 tenant may find that creating new Groups requires IT approval. Someone using a legacy Outlook license without a Microsoft 365 subscription won't see the Groups pane at all. And a Mac user familiar with Windows Outlook will notice enough interface differences to cause initial confusion.

What makes the most sense — a Contact Group for quick personal use, or a full Microsoft 365 Group with shared resources — depends on whether you're managing a mailing list for yourself or coordinating with a team that needs shared access to files, conversations, and calendars. The right approach sits at the intersection of your account type, your organization's configuration, and what you actually need the group to do.
