What a group is and why you'd create 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 sends to all five. Groups live in your Contacts and work across Outlook on the web, Outlook desktop, and Outlook on your phone.

Groups are different from distribution lists (which only work in some workplaces) and different from creating a folder to sort incoming mail. A group is purely for sending — it's a shortcut to reach the same people repeatedly.

You create a group when you email the same cluster of people regularly: a sports team, a project team at work, family members, or friends planning something together. Once it exists, you can add or remove people from it anytime.

Key Takeaways

  • Groups are lists of email addresses saved under one name, and you create them in your Contacts, not in your inbox.
  • The steps differ slightly depending on whether you use Outlook on the web, Outlook desktop, or Outlook on your phone.
  • You can add people to a group when you create it, or add them later by editing the group.
  • Once a group exists, typing its name in the To field sends your message to everyone in it at once.

Creating a group in Outlook on the web

Open Outlook in your browser and go to your Contacts. In the left sidebar, look for "New contact group" or a plus sign next to "Groups" — the exact wording depends on your version. Click it.

A form appears asking for a group name. Type a clear name: "Book Club", "Marketing Team", "Family". Then click "Add members" or the plus icon next to "Members".

A box opens where you can search for and add people. Type a person's name or email address, click their name when it appears, and they're added to the list. Repeat until everyone is in the group. When you're done adding people, click outside the box or press Enter, then click "Create" or "Save".

The group now appears in your Contacts under Groups. To use it, open a new email, click in the To field, type the group name, and it appears as an option. Click it and all members are added to that message.

Creating a group in Outlook desktop

Open Outlook on your computer. Click the "People" icon at the bottom left (or "Contacts" depending on your version). In the Home tab at the top, click "New Contact Group".

A window opens with a blank group form. Type the group name in the field at the top. Then click "Add Members" in the ribbon, and a dropdown menu appears with two options: "From Outlook Contacts" or "From Directory" (if your workplace has one).

Click "From Outlook Contacts". A dialog box opens showing your contacts. Click each person you want to add — they highlight when selected. Click "OK" when you've chosen everyone. If someone isn't in your contacts yet, click "Add Members" again and choose "New Email Contact" to add them first.

Once all members are listed in the group window, click "Save & Close" at the top left. The group is now saved. To use it, open a new email, type the group name in the To field, and Outlook fills in all the addresses.

Creating a group on Outlook mobile

Open Outlook on your phone and tap the People icon at the bottom. Tap the plus sign or "New" button. Look for an option that says "New group" or "Create group" — this varies by phone and Outlook version.

Type the group name. Then tap "Add members" or the plus icon. Search for each person by name or email, tap their name to add them, and repeat until the group is complete. Tap "Done" or "Save".

On some phones, the group option is less visible. If you don't see it, try opening a new email, tapping the To field, and looking for a "Create group" option there instead. The process is the same — name the group and add members — but you're creating it from the email screen rather than from Contacts.

Adding or removing people from an existing group

You don't have to get the group perfect the first time. To change who's in a group, open your Contacts, find the group name, and click or tap it to open it.

In Outlook on the web, click "Edit" or the pencil icon. In Outlook desktop, right-click the group and choose "Edit". On mobile, tap "Edit" or the pencil icon. A form opens showing the current members.

To add someone, click "Add members" or the plus icon, search for their name, and click to add them. To remove someone, click the X or minus sign next to their name. When you're done, click "Save" or "Done".

Changes take effect when ready. The next email you send to that group will include the updated list.

Common mistakes and how to avoid them

The most common mistake is looking for groups in your inbox or folder list instead of in Contacts. Groups live only in Contacts — they're not folders for organizing mail you've already received. If you want to sort incoming emails from certain people, create a folder instead and set up a rule to move their messages there.

Another mistake is typing a group name in the To field and having it not appear. This usually means the group name has a typo, or you're using a version of Outlook that doesn't recognize groups created on a different device. Try opening Contacts, clicking the group, and copying its exact name to paste into the To field.

A third issue: sending a test email to a group and realizing someone's address is wrong or outdated. Before sending to a large group for the first time, open the group in Contacts and scan the member list to make sure everyone's address looks correct.

When to use a group versus other Outlook features

Use a group when you send to the same set of people regularly and want a quick way to reach them all. Use a folder when you want to sort and store emails you've already received. Use a rule (in Outlook desktop) when you want Outlook to automatically move incoming mail from certain people into a folder.

If you're in a workplace with a shared mailbox or distribution list, those are different from groups and are usually set up by your IT department. Groups are personal — only you see them and can use them. If you want to share a group with coworkers, you'd have to tell them the member list and they'd create their own group with the same people.

Frequently Asked Questions

Can I create a group with just two people?

Yes. Groups work for any number of people, from two to hundreds. There's no minimum or maximum, so create a group whenever it saves you time typing addresses, even if it's just two people you email together regularly.

What happens if I send an email to a group and then add a new person to it?

The new person doesn't receive the email you already sent. They only receive emails sent to the group after they're added. If you need them to see the old email, forward it to them separately or add them to the group before sending.

Can people see who else is in a group when I email them?

Yes, if you use the To field. Everyone in the To field can see everyone else's address. If you want to hide the list, use the Bcc (blind carbon copy) field instead — but then you can't use a group name, so you'd have to add addresses individually.

Do groups work the same way on my phone as on my computer?

Groups work the same way, but the steps to create and edit them are slightly different because phone screens are smaller. A group created on your computer appears on your phone, and vice versa, as long as you're signed into the same Outlook account.

What if someone's email address changes and they're in one of my groups?

Open the group, edit it, remove the person with the old address, and add them again with their new address. Outlook doesn't automatically update addresses, so you have to do it manually when someone changes their email.
