What a contact group is and why you'd use one
A contact group in Outlook is a saved list of email addresses under a single name. Instead of typing five email addresses every time you want to email your team, you type the group name once and Outlook sends to everyone in it. You create the group once, add people to it, and then reuse it whenever you need to reach that same set of people.
Contact groups live in Outlook on the web, in the Outlook desktop app for Windows, and in Outlook for Mac. The steps differ slightly depending on which version you use, but the idea is the same: you pick a group, add names to it, and save it.
Key Takeaways
- A contact group is a saved list of email addresses that you can send to all at once by typing one group name.
- You can add someone to a contact group by opening the group, clicking add member, and typing their name or email address.
- Contact groups in Outlook on the web are called distribution lists and work the same way as groups in the desktop app.
- Once you add someone to a group, they stay in that group until you remove them — you do not have to add them again next time.
Adding someone to a contact group in Outlook on the web
Open Outlook in your web browser and go to the People section by clicking the grid icon in the bottom left corner and selecting People. Find the contact group you want to add someone to — it will have a people icon next to its name, not a single person icon. Click on the group name to open it.
Once the group is open, you will see a list of the people already in it. Look for a button that says "Add member" or a plus icon near the top of the member list. Click it. A box will appear asking you to type a name or email address. Start typing the person's name — Outlook will show you matching contacts as you type. Click the person you want to add. If they are not in your contacts yet, you can type their full email address instead and Outlook will add them.
After you click the person's name, they appear in the member list. The group saves automatically in Outlook on the web, so you do not need to click a save button. The person is now part of the group and will receive emails sent to that group name.
Adding someone to a contact group in Outlook for Windows
Open Outlook and go to the People view by clicking the People icon in the left sidebar. Find the contact group you want to edit and double-click it to open it. You will see a window showing the group name and the current members.
Click the "Add Members" button near the top of the window. A dialog box will open with a list of your contacts. Find the person you want to add by scrolling or typing their name in the search box. Click their name to select them, then click OK. If the person is not in your contacts, click "New Contact" at the bottom of the dialog, enter their email address, and then add them to the group.
After you add the person, click Save and Close. The group now includes the new member. The next time you address an email to this group, the new person will receive it.
Adding someone to a contact group in Outlook for Mac
Open Outlook and click the People icon in the left sidebar. Find your contact group and double-click it. The group window will show you the current members and a toolbar at the top.
Click the plus icon (+) in the toolbar to add a new member. A contact picker will appear. Type the person's name or email address. When you see them in the list, click their name to select them. Click Add. If the person does not appear in your contacts, you can type their email address directly and Outlook will add them as a new contact and add them to the group at the same time.
Close the group window when you are done. Outlook saves the change automatically. The person is now in the group and will be included the next time you send an email to the group.
What happens when you add someone who is not in your contacts yet
If you try to add someone by typing their email address and they do not already exist in your Outlook contacts, Outlook handles this differently depending on your version. In Outlook on the web and Outlook for Mac, you can type an email address directly into the add member field and Outlook will add them without creating a separate contact first. In Outlook for Windows, you may need to create them as a contact first, or you can type their email address in the add member dialog and Outlook will add them to the group.
The person does not need to be in your contacts for the group to work. Once they are added to the group, emails sent to the group name will reach them at their email address, whether or not they appear in your personal contact list.
Removing someone from a contact group
If you need to remove someone from a group later, open the group the same way you opened it to add them. Find the person's name in the member list, click on it to select it, and look for a remove button or delete icon — usually an X or a minus sign. Click it and confirm the removal. Save the group if your version of Outlook requires it.
Removing someone from a group does not delete them from your contacts. It only removes them from that specific group. They will no longer receive emails sent to the group name, but they remain in your contact list if they were there before.
Troubleshooting: person added but emails are not reaching them
If you added someone to a group but they say they are not receiving emails sent to the group, check that their email address in the group is spelled correctly. Open the group, find their name, and verify the address matches what they gave you. A single typo will cause emails to bounce.
If the address is correct, ask the person to check their spam or junk folder — sometimes group emails are filtered there by mistake. If they are still not receiving anything, try sending a test email to the group and ask them to confirm whether it arrives. If it does not, the problem may be on their email provider's end, not in Outlook.
Frequently Asked Questions
Can I add the same person to multiple contact groups?
Yes. A person can be in as many groups as you want. Adding them to one group does not remove them from another. You can have one person in a "Team" group, a "Project A" group, and a "Vendors" group all at the same time.
What is the difference between a contact group and a distribution list?
In Outlook on the web, contact groups are called distribution lists, but they work the same way. Both are saved lists of email addresses that you can send to all at once. The name is just different depending on which version of Outlook you are using.
If I add someone to a group, do they know they are in it?
No. Adding someone to a contact group does not send them a notification. They only find out they are in the group when they receive an email sent to the group name, and even then they may not realize it was sent to a group rather than to them individually.
Can I add a contact group to another contact group?
In some versions of Outlook you can nest groups — add one group inside another — but this is not supported in all versions. Check your version's documentation or try adding a group name to another group to see if Outlook accepts it. If it does not work, you will need to add individual people instead.
What happens to a group if I delete someone from my contacts?
Deleting a contact from your contact list does not automatically remove them from any groups they are in. The group still has their email address saved, and they will continue to receive emails sent to the group. If you want to remove them from the group, you must open the group and remove them separately.
