Outlook Email Group Guide

How to Create an Email Group in Outlook

There are three ways to create an email group in Outlook: a contact group (a personal list, best for most people), a Microsoft 365 group (a shared workspace with its own address), and an admin-created list (for whole organizations). Here's how to set up each one, step by step.

Looking for the admin-managed kind specifically? Our guide to create a distribution list in Outlook covers that route in full, including the Microsoft 365 admin center.

The Three Kinds of "Group" in Outlook (Pick the Right One First)

Microsoft uses the word "group" for three different features, which is why half the guides you'll find seem to describe a different screen than the one in front of you. Two minutes here saves you twenty minutes of clicking through menus that do not exist in your version.

If you're using a personal Outlook.com account, only the first option exists - Microsoft 365 groups and admin-managed lists need a work or school account. (That's the answer to "why can't I create groups in Outlook?" - the feature isn't in personal accounts.)

Not sure which account you have? Look at the address you sign in with. Anything ending in outlook.com, hotmail.com, or live.com is a personal Microsoft account. An address at your employer's, school's, or organization's own domain is a work or school account, and that's the one that unlocks the other two options - assuming your admin hasn't restricted them.

For most people reading this - a club secretary, a committee chair, a team lead, a parent coordinating a year group - the answer is the contact group. It is the only one that works on any account, needs nobody's permission, and takes two minutes. Start there, and read the catch further down before you build a group you'll be maintaining for years.

How to Create a Contact Group in Outlook (The Way Most People Want)

A contact group is a saved set of addresses you can message with one entry. It works on any Outlook account - personal or work - and takes about two minutes. The steps differ slightly depending on which Outlook you have, so pick your version below.

New Outlook and Outlook on the web

New Outlook for Windows and Outlook in a browser share the same interface, so these steps cover both. If your Outlook has a New Outlook toggle in the top-right corner rather than a classic File / Home / Send-Receive ribbon, this is your version.

Step 1: Select the People icon in the left-hand navigation pane. This opens your contacts.

Step 2: Select the arrow next to New contact at the top of the page, then choose New contact list. (In some builds you'll find the same option under a Contact Lists folder in the sidebar.)

Step 3: Give the group a name people will recognise in a To field - "Book Club," "Committee 2026," "Under-11s Parents." Then add members: type or paste email addresses, separated by semicolons. Existing contacts autocomplete as you type.

Step 4: Select Create. The group is saved and ready to use - type the group name in the To or BCC field to send.

Classic Outlook for Windows

Classic Outlook calls the same feature a Contact Group and puts it in the ribbon.

1. Select the People icon in the bottom-left navigation bar.
2. On the Home tab, select New Contact Group. A new window opens.
3. Type a name for the group in the Name field.
4. Select Add Members, then choose from Outlook Contacts, from your Address Book, or New E-mail Contact to type an address that isn't saved yet. You can mix all three.
5. Select Save & Close. The group now appears in your contacts.

How to Create a Microsoft 365 Group in Outlook

A Microsoft 365 group is a bigger thing than a saved set of addresses: it comes with its own email address, a shared inbox, a shared calendar, a SharePoint document library, and a Teams presence if your organization uses Teams. You need a work or school account to create one.

1. In Outlook, find Groups in the folder pane on the left.
2. Select New group (in classic Outlook, it's New Group on the Home tab).
3. Enter a name and description. Outlook proposes a group email address based on the name - check it before continuing, because it's awkward to change later.
4. Choose the privacy setting: Private (members must be added or approved) or Public (anyone in your organization can join).
5. Add members, then select Create.

If New group is missing or greyed out, it's not a bug: either you're on a personal account, or your admin has restricted who can create groups. Both are common.

The honest caveat: a Microsoft 365 group gives everyone another inbox and workspace to check, and conversations sent to the group inbox are easy to miss unless members subscribe to have them delivered to their own inbox. If all you want is one email reaching everyone, this is overkill.

How to Send a Group Email in Outlook

Once the group exists, sending to it is the easy part. Compose a new message and start typing the group's name in the To field. Outlook suggests it as you type; select it and every member's address is filled in.

One decision worth making deliberately: To or BCC. Addresses in the To field are visible to every recipient. For a committee of six that's fine; for a 200-person community list it is a privacy problem, and one careless "Reply All" turns it into an inbox problem for everyone. Putting your own address in To and the group in BCC hides the member list - but replies then come back only to you, not to the group.

There's a fuller walkthrough of that trade-off in our guide to sending a group email without showing recipients.

The Catch: Your Email Group Only Works for You

A contact group lives in your contacts. Your co-organizer can't send to it, nobody can unsubscribe themselves, there's no archive, and when you email more than a handful of people you'll hit Outlook's recipient limits and spam-filter problems. Groups run this way tend to live in one volunteer's account - and leave with them.

In practice that shows up as:

• Only one person can send. Sharing means forwarding a copy of the group, which immediately drifts out of date.
• Replies don't reach the group. They go to whoever sent the message, who then forwards them by hand.
• You are the membership system. Every join, leave, and address change is an email to you and an edit by you.
• No shared history. A new member has no way to see what was discussed before they arrived.
• Sending limits. Roughly 500 recipients per message on Outlook.com, with lower daily caps on new accounts - and large sends from a personal mailbox are more likely to be filtered as spam.

A Simpler Option: A Group Address That Works for Everyone

If the group is ongoing - a club, a committee, a team, a congregation - the fix is to stop storing the list in one person's contacts and give the group its own address.

Gaggle Mail gives you one address like yourgroup@gaggle.email. Anyone you allow can send to it, and everyone in the group receives it. Members join and leave themselves, every message is kept in a shared archive, and addresses stay private. It works with Outlook and every other email app - nobody has to sign up for anything or change how they read their mail.

• One address for the group, not a list in one account
• Replies go to everyone - or just the sender, your choice
• Self-service join and leave, so you're not the membership desk
• Shared archive so new members can catch up
• Moderation and digests when a group gets busy
