Adding a group email in Outlook
A group email (also called a distribution list) is a single email address that sends your message to multiple people at once. In Outlook, you create this by building a contact group, then adding the individual email addresses you want included. When you send to that group address, everyone in it receives the message.
The steps differ slightly depending on whether you use Outlook on the web, Outlook desktop for Windows, or Outlook for Mac. All three let you create groups, but the menu locations are different. Once you set up a group, you can use it like any other contact — type the group name in the "To" field and Outlook fills in all the member addresses automatically.
Key Takeaways
- A group email address sends one message to multiple people without typing each address separately.
- In Outlook desktop, you create a group through Contacts or the People pane, then add members by typing their email addresses.
- In Outlook on the web, you build a group in the Contacts section and can add members one at a time or paste multiple addresses.
- Once created, a group appears in your contact list and works like a regular contact when you compose a message.
- You can edit a group later to add or remove members, and changes take effect the next time you send to that group.
Creating a group in Outlook desktop (Windows)
Open Outlook and go to the People pane on the left side of the window. At the bottom of the People pane, click the three dots (more options) and select New Contact Group. A dialog box opens where you type a name for your group — something like "Marketing Team" or "Project Leads".
Click Add Members and choose Add from Outlook Contacts if the people are already in your contact list. A window appears showing your contacts; select the ones you want and click Add. If someone is not in your contacts yet, click Add Members again and choose New Email Contact, then type their name and email address.
Once you have added everyone, click Save & Close. The group now appears in your People pane and in your contact list. When you compose a new email and type the group name in the "To" field, Outlook shows the group as an option — click it to add all members at once.
Creating a group in Outlook on the web
Sign in to Outlook on the web and click the People icon in the left navigation bar. At the top of the page, click New Contact Group (or New Group, depending on your version). Type a name for the group and optionally add a description.
Click Add Members and start typing a person's name or email address. Outlook shows matching contacts as you type; click the person's name to add them. Repeat this for each member. You can also paste multiple email addresses separated by semicolons or commas if you have them in a list elsewhere.
Once all members are added, click Create at the bottom. The group is now saved and appears in your contacts. When you compose an email and type the group name in the "To" field, Outlook recognizes it and fills in all member addresses.
Creating a group in Outlook for Mac
Open Outlook and click File in the menu bar, then select New and Contact Group. A window opens where you type the group name. Click the plus sign (+) button to add members one at a time, or drag existing contacts from your address book into the group window.
If you need to add someone not in your contacts, click the plus button and type their name and email address in the fields that appear. Once you have added all members, close the window — Outlook saves the group automatically. The group now appears in your contacts and works the same way as in the Windows version: type the group name when composing an email and Outlook fills in all addresses.
Editing or removing a group
To change a group after you create it, find it in your contacts and open it. In Outlook desktop, right-click the group and select Edit Contact Group. In Outlook on the web, click the group name and then click Edit. You can now add new members, remove existing ones, or change the group name.
To remove someone from the group, find their name in the member list and click the X or delete button next to it. To add someone new, use the Add Members button again. When you finish editing, click Save or Save & Close. The next time you send an email to that group, it uses the updated member list.
When to use a group versus individual addresses
A group email works best when you send to the same set of people regularly — a team, a committee, or a recurring meeting attendee list. Instead of typing five email addresses every time, you type one group name. If the group membership changes, you update it once and all future emails use the new list.
For a one-time message to multiple people, typing individual addresses or using the "To" field to search for names is often faster than creating a group. But if you find yourself sending to the same people more than twice, creating a group saves time and reduces the chance of forgetting someone.
Frequently Asked Questions
Can I create a group that includes other groups?
Yes. When you add members to a group, you can select another group you have already created. This is useful for large organizations where you might have a "All Staff" group that includes "Sales Team" and "Support Team" groups. Changes to the smaller groups automatically update the larger one.
What happens if someone in my group changes their email address?
You need to edit the group and update their address manually. Open the group, find their name, and change the email address. Outlook does not automatically update member addresses if someone's email changes at their organization.
Can people see who else is in a group when I send an email to it?
Yes, by default. When you send to a group, all recipients can see the other member addresses in the message header. If you want to hide the member list, use the "Bcc" (blind carbon copy) field instead of "To" when sending to the group, though this requires typing the group name in Bcc rather than To.
Is there a limit to how many people can be in a group?
Outlook itself has no hard limit, but your email provider may. Most organizations allow groups with hundreds of members. If you are hitting a limit, check with your IT department or email provider about their specific rules.
Can I share a group with coworkers so they can use it too?
In Outlook desktop, groups are stored locally on your computer and cannot be shared. In Outlook on the web, you can create a shared contact group through your organization's directory if your administrator has set this up, but standard personal groups are not shared by default. Check with your IT department about shared distribution lists for your organization.
