What a group is and why you'd make one

A group in Outlook is a saved list of email addresses under one name. Instead of typing five people's addresses every time you email your book club, you type the group name once and Outlook fills in all five addresses. Groups live in your contacts, not in your inbox, so they stay organized separately from your mail.

Groups are useful for any set of people you email together regularly — a work project team, a family chain, a volunteer committee. You create the group once, add the people, and then use it for years. If someone's email changes, you update it in one place and the group automatically uses the new address next time.

The steps differ slightly depending on whether you use Outlook on your computer, Outlook on the web, or Outlook on your phone. This guide covers the desktop version first, then the web version, because those are where most people create groups.

Key Takeaways

  • A group is a single name that holds multiple email addresses, so you can send one message to everyone at once without typing each address.
  • On desktop Outlook, you create a group through the People tab, name it, and then add contacts one at a time or paste a list.
  • On Outlook on the web, groups live under Contacts and work the same way, though the buttons are in slightly different places.
  • Once you create a group, you can use it in the To, Cc, or Bcc field just like you would a single person's address.
  • If you delete a group, the contacts inside it stay in your address book — only the grouping disappears.

Creating a group in Outlook on your computer

Open Outlook and click the People tab at the bottom of the window (or press Ctrl+3). This opens your contacts. At the top of the window, look for the New Contact Group button — it usually sits in the ribbon near the left side. Click it.

A new window opens with a blank group. In the Name field at the top, type the name you want — something like "Book Club" or "Marketing Team". This is the name that will appear in your address book and the name you'll type when you want to send mail to everyone in the group.

Below the name field, you'll see an empty box. This is where the group members go. Click the Add Members button (it's usually in the ribbon or near the member box). A small window pops up with options: you can add members from your contacts, from your address book, or from a new email address you type in.

If the person is already in your contacts, click From Outlook Contacts, find their name in the list, click it, and then click Add. Repeat this for each person. If someone isn't in your contacts yet, click New Email Address, type their name and email, and click OK. When you're done adding people, click Save & Close at the top of the group window.

Creating a group in Outlook on the web

Log into Outlook on the web and click People in the left sidebar. At the top of the page, click New and then select Group from the dropdown menu. (If you don't see a dropdown, look for a small arrow next to the New button.)

Type the group name in the field that appears. Below that, you'll see a box where you can add members. Click in the box and start typing someone's name or email address. Outlook shows you matching contacts as you type. Click the person's name to add them. Repeat for each member.

Once everyone is added, click Create at the bottom. The group is now saved and appears in your contacts list. You can go back and edit it anytime by clicking the group name and then clicking the pencil icon (Edit).

Adding or removing people from an existing group

To change who's in a group, open your contacts and find the group name. On desktop Outlook, double-click the group to open it. On Outlook on the web, click the group name and then click the pencil icon. Either way, you'll see the group window with all current members listed.

To add someone new, click Add Members (desktop) or click in the member box and type a name (web). To remove someone, click their name in the member list and then click the Remove button or press Delete. When you're done, click Save & Close (desktop) or Save (web).

Using a group to send email

Once your group exists, using it is straightforward. Open a new email and click in the To field. Type the group name — Outlook will show you the group in a dropdown list. Click it to add the whole group to the message. You can also use groups in the Cc or Bcc fields the same way.

When you send the message, everyone in the group receives it. If you later change who's in the group, the new member list takes effect the next time you use the group — past emails don't change.

What happens when you delete a group

If you delete a group, the group itself disappears from your contacts, but all the people in it stay in your address book. You're only removing the grouping, not the contacts. If you realize you deleted a group by mistake, you can recreate it and add the same people back in.

This is different from deleting a contact — if you delete a single person from your address book, they're gone entirely. Groups are just organizational containers, so deleting one is always reversible as long as you remember who was in it.

Frequently Asked Questions

Can I send an email to a group and have replies go only to me, not to everyone?

Yes. When you send to a group, recipients see only their own copy of the email — they don't automatically see replies from other group members unless you put the group in the Cc or Reply-To field. If you want replies to go to the whole group, you have to set that up separately, usually by creating a shared mailbox or distribution list through your organization's email administrator.

What's the difference between a group and a distribution list?

A group is personal — it lives in your contacts and only you can use it. A distribution list is usually created by your organization's IT department and can be used by anyone in the company. For personal use, groups are what you create yourself. For work, your administrator might set up distribution lists that work similarly but are managed centrally.

Can I create a group on my phone?

On the Outlook mobile app, you can view and use groups, but you can't create new ones. You have to create groups on your computer or on Outlook on the web, then they sync to your phone automatically. Once they're there, you can use them to send mail just like on desktop.

If I add someone to a group, do they know they're in it?

No. Adding someone to a group doesn't notify them. They only find out when they receive an email sent to the group. There's no "you've been added to a group" message — it's invisible to them unless you tell them separately.

Can I have the same person in multiple groups?

Yes. One contact can belong to as many groups as you want. If your friend is both in your "Book Club" group and your "Hiking Friends" group, they'll receive emails sent to either group. Changing their contact information updates it in all groups at once.
