What a distribution list does and when to use it

A distribution list in Outlook is a saved group of email addresses that you can send to all at once by typing one name. Instead of typing five coworkers' addresses separately or copying and pasting the same list each time, you create the list once, give it a name like "Marketing Team" or "Monthly Reviewers", and then address an email to that name. Outlook expands it to all the addresses when you send.

Distribution lists save time if you regularly email the same group — a project team, a committee, family members, or people who need the same monthly report. They also reduce the chance you'll forget someone or accidentally include the wrong person. You control who is in the list, so you can update it whenever someone joins or leaves the group.

Outlook calls these lists by different names depending on your version: "distribution list", "distribution group", or "contact group". The steps are slightly different in Outlook on the web versus Outlook desktop, so this guide covers both.

Key Takeaways

  • A distribution list lets you send one email to multiple people by typing a single name instead of entering each address separately.
  • In Outlook desktop, you create a distribution list through Contacts by selecting multiple people and choosing "Create Group".
  • In Outlook on the web, you go to Contacts, select people, and use the "Create contact group" option from the toolbar.
  • You can add or remove people from the list anytime, and changes take effect the next time you use it to send an email.
  • Distribution lists are stored locally on your computer (desktop) or in your Outlook account (web), so they travel with you when you sign in elsewhere.

Creating a distribution list in Outlook desktop

Open Outlook and go to the Contacts folder — you'll see it in the left sidebar under your mailbox name. If you don't see Contacts, click the folder icon at the bottom left and look for it there. Once you're in Contacts, find the people you want to add to the list. You can search for them by name if your contact list is long.

Select the first person by clicking their name. Then hold Ctrl and click each additional person you want in the group. Once all are selected (they'll be highlighted), right-click on one of the selected names. A menu will appear — look for an option that says "Create Group" or "Create Contact Group" depending on your Outlook version. Click it.

A new window opens with a blank group. At the top, you'll see a field labeled "Group Name" — type the name you want to use, like "Q4 Budget Review" or "Client Feedback Team". The people you selected are already listed below. Click "Save & Close" when you're done. The group now appears in your Contacts folder and is ready to use.

Creating a distribution list in Outlook on the web

Sign into Outlook on the web and click the People icon in the left sidebar (it looks like a person's silhouette). This opens your contacts. Find the people you want to add to the list by searching or scrolling through your contacts.

Click the first person's name to select them. Then hold Ctrl (or Cmd on Mac) and click each additional person. Once all are selected, look at the toolbar above the contact list — you'll see a "Create contact group" button. Click it. A new window appears asking you to name the group. Type a clear name and click "Create". The group is now saved and ready to use.

How to use your distribution list to send an email

Once your distribution list exists, using it is straightforward. Open a new email in Outlook. In the "To" field, start typing the name of your distribution list. Outlook will suggest it as you type — click on it to select it. The list name appears in the To field, and when you send the email, it goes to everyone in that list.

If you want to see who is actually in the list before you send, click on the list name in the To field and a preview will show you all the addresses. This is useful if you haven't used the list in a while and want to confirm the membership is still correct.

Adding or removing people from an existing distribution list

You can change a distribution list anytime. In Outlook desktop, go to Contacts, find the group name, and double-click it to open it. You'll see the current members listed. To add someone, click the "Add Members" button (or similar wording depending on your version), search for the person, and click to add them. To remove someone, click their name in the list and press Delete or look for a remove button. Click "Save & Close" when done.

In Outlook on the web, go to People, find the group, and click on it to open it. Look for an "Edit" button or pencil icon. Click it to enter edit mode. You can then add new members by clicking an add button and searching for their name, or remove members by clicking an X or delete icon next to their name. Save your changes when finished.

Distribution lists versus forwarding rules and shared mailboxes

A distribution list is different from a forwarding rule. A forwarding rule automatically sends every email you receive from one person to another person — it's about redirecting your own mail. A distribution list is about sending one email you compose to many people at once. They solve different problems.

A shared mailbox is also different. In a shared mailbox, multiple people have access to the same inbox and can read and reply to the same emails. A distribution list doesn't give anyone access to anything — it's just a shortcut for addressing. Use a distribution list when you want to send the same message to a group; use a shared mailbox when a group needs to manage the same incoming mail together.

Troubleshooting: Why your distribution list might not work

If you type a distribution list name and Outlook doesn't recognize it, the list may not be saved in the right place. In Outlook desktop, make sure you created it in your Contacts folder, not in a subfolder. If you created it in a subfolder by accident, move it to the main Contacts folder and try again.

If you're using Outlook on the web and the list doesn't appear, refresh the page or sign out and back in. Sometimes the interface needs a moment to sync. If you recently added someone to the list, wait a few minutes before sending — Outlook on the web sometimes takes time to update group membership.

If you're on a work account with restrictions, your administrator may have disabled distribution lists or limited who can create them. Contact your IT department to ask whether distribution lists are available for your account.

Frequently Asked Questions

Can I create a distribution list with people who aren't in my contacts yet?

No — you need to add them to your Contacts first. Create a new contact for each person (with their email address), then create the distribution list from those contacts. Once the list exists, you can edit it to add more people later.

What happens if someone in my distribution list changes their email address?

You need to update the list manually. Open the group, remove the person with the old address, and add them again with their new address. Outlook doesn't automatically update email addresses in groups.

Can I send a distribution list to someone else so they can use it?

Not directly — distribution lists are stored in your own Outlook account and don't transfer to other people. If someone else needs the same group, they have to create their own list with the same people. In a work environment, your administrator can create organization-wide distribution lists that everyone can use.

Is there a limit to how many people can be in a distribution list?

Outlook desktop has no practical limit. Outlook on the web can handle hundreds of members, though very large lists may slow down your account slightly. If you're regularly emailing more than a few hundred people, ask your IT department about organization-wide groups instead.

Can I create a distribution list that includes other distribution lists?

Yes, in Outlook desktop you can add a group to another group. In Outlook on the web, this depends on your account type — it works with work accounts but may not work with personal Microsoft accounts. Try adding the group name to see if it works for your setup.
