What a distribution group does and why you'd make one

A distribution group in Outlook is a single name you can type into an email's "To" field that sends your message to multiple people at once. Instead of typing five email addresses separately, you type one group name — like "Marketing Team" or "Project Leads" — and Outlook expands it to everyone in that group when you send.

You create a distribution group when you regularly email the same set of people. It saves typing, reduces mistakes, and makes sure nobody gets left out by accident. The group lives in your Outlook contacts, and only you can see and use it unless you share it with others.

Key Takeaways

  • A distribution group is a saved list of email addresses under one name that you can use to email multiple people at once.
  • You create a distribution group in Outlook by opening Contacts, selecting New Contact Group, naming it, and adding members one by one or by importing from your existing contacts.
  • Distribution groups work in Outlook desktop, Outlook on the web, and Outlook mobile, though the steps differ slightly between versions.
  • You can edit a group anytime to add or remove people, and you can share the group with coworkers so they can use it too.

Creating a distribution group in Outlook desktop

Open Outlook and go to the People tab at the bottom left of the window. In the ribbon at the top, click New Contact Group (in older versions of Outlook, this may say "New Distribution List"). A blank contact group window opens.

Type a name for your group in the field at the top — something clear like "Weekly Standup" or "Board Members". Then click Add Members in the ribbon. A dialog box appears with two options: Add from Outlook Contacts and New Email Contact. Choose Add from Outlook Contacts if the people are already in your contacts. A list of your contacts appears; click each person you want to add, then click Members to move them into the group. Click OK when you're done adding people.

If someone isn't in your contacts yet, click New Email Contact instead, type their name and email address, and they'll be added to the group. When all members are in the group, click Save & Close. The group now appears in your Contacts and is ready to use.

Creating a distribution group in Outlook on the web

Log into Outlook on the web and click the People icon in the left sidebar. At the top of the page, click New and select Contact group from the dropdown menu. A form appears asking for the group name.

Type the group name and then click in the Add members field. Start typing a person's name or email address; Outlook shows matching contacts from your address book. Click the person's name to add them. Repeat for each member. You can also click the + icon next to the field to browse your full contact list. When all members are added, click Create at the bottom of the form.

Creating a distribution group in Outlook mobile

Open Outlook on your phone or tablet and tap the People tab at the bottom. Tap the + icon or New button (the exact location depends on your device and Outlook version). Look for an option to create a contact group or distribution list.

Type the group name, then tap the field to add members. Your contacts list appears; tap each person you want to add. When you're done, tap Save or Done. The group is now saved and you can use it to send emails from your phone.

Adding and removing members after you create the group

You can change a distribution group anytime. In Outlook desktop, go to People, find the group in your contacts, and double-click it to open it. Click Add Members to add new people, or right-click a member's name and select Remove to take them out. Click Save & Close when you're done.

In Outlook on the web, click the group name in your contacts, then click Edit at the top. You can add members using the Add members field or remove them by clicking the X next to their name. Click Save when finished. Mobile works the same way: open the group, tap Edit, add or remove members, and tap Save.

Sharing a distribution group with coworkers

If you want coworkers to use a group you created, you can share it with them. In Outlook desktop, right-click the group in your Contacts and select Share. Choose the people you want to share it with and click Send. They'll receive an email with the group attached; when they open it, the group is added to their contacts.

In Outlook on the web, open the group and look for a Share button or option in the menu. Enter the email addresses of people you want to share with and send. Note that sharing works best within the same organization; sharing with people outside your company may have restrictions depending on your email setup.

Differences between distribution groups and contact groups

In Outlook, "distribution group" and "contact group" are often used interchangeably, but they can mean slightly different things depending on your version and setup. A contact group is what you create in Outlook for personal use — it's stored on your computer or in your online account. A distribution group in a work setting usually refers to a group created by your IT department or email administrator and shared across your entire organization.

For most people creating their own groups in Outlook, you're making a contact group. The steps are the same, and it works the same way when you send an email. The main difference is that organization-wide distribution groups are managed by IT and appear in everyone's address book, while your personal groups only appear in your own contacts unless you share them.

Frequently Asked Questions

Can I send an email to a distribution group and have it look like it went to individuals?

No. When you send to a distribution group, the email goes to the group address, and all members receive it. They can see that the email was sent to the group name, not to them individually. If you need each person to receive an individual email, you'll have to send separate messages or use your email's mail merge feature if available.

What happens if I delete someone from a distribution group?

They're removed from the group when ready. Any future emails you send to that group won't go to them. Past emails they already received are not affected. If you remove someone by mistake, you can add them back by opening the group and clicking Add Members again.

Can I create a distribution group that includes other distribution groups?

In Outlook desktop and on the web, you can add a group to another group by selecting it as a member, though this works best with organization-wide groups set up by IT. Personal contact groups have limits on nesting, so test it with your setup to see if it works the way you need.

Do distribution groups work across different email providers?

Distribution groups only work within Outlook and with people who use the same email system as you. If you use Gmail or another email service, you'll need to use that service's equivalent feature — Gmail calls it a "contact group" and the steps are different. You can't use an Outlook distribution group in Gmail or vice versa.

What's the maximum number of people I can add to a distribution group?

Outlook doesn't set a hard limit on group size for personal contact groups. However, if your organization uses Exchange Server or Microsoft 365, there may be limits on how large a distribution group can be. Check with your IT department if you're creating a very large group for work.
